Age-related cognitive decline has become an increasingly relevant public health issue. However, risk and protective factors of cognitive decline have yet to be investigated prospectively taking into account genetic, lifestyle, physical and mental health factors. Population-based data from middle-aged (40 to 59 years; N = 2,764) and older individuals (60 to 80 years; N = 1,254) were drawn from a prospective community cohort study using the Tower of London (TOL) planning task. Assessments were repeated at a 5-year interval to investigate age-related changes in planning performance and to determine the impact of risk and protective factors. Planning performance improved in middle-aged, but declined in older participants over 5 years. SNPs affecting the dopamine system (COMT, DRD2) and APOE polymorphisms differentially predicted cognitive performance in older vs. middle-aged individuals. For older individuals, high alcohol consumption, antidepressant medication and living without a partner had additional negative predictive power on cognition. In contrast, undiagnosed hypertension, no obstructive lung disease, and fewer years of education predicted cognitive decline in the middle-aged group. The results inform screening for individuals particularly vulnerable to cognitive decline and interventions (e.g., focusing on lifestyle factors) to help maintain cognitive performance into old age.

Diphthamide, a post-translationally modified histidine residue of eukaryotic TRANSLATION ELONGATION FACTOR2 (eEF2), is the human host cell-sensitizing target of diphtheria toxin. Diphthamide biosynthesis depends on the 4Fe-4S-cluster protein Dph1 catalyzing the first committed step, as well as Dph2 to Dph7, in yeast and mammals. Here we show that diphthamide modification of eEF2 is conserved in Arabidopsis thaliana and requires AtDPH1. Ribosomal −1 frameshifting-error rates are increased in Arabidopsis dph1 mutants, similar to yeast and mice. Compared to the wild type, shorter roots and smaller rosettes of dph1 mutants result from fewer formed cells. TARGET OF RAPAMYCIN (TOR) kinase activity is attenuated, and autophagy is activated, in dph1 mutants. Under abiotic stress diphthamide-unmodified eEF2 accumulates in wild-type seedlings, most strongly upon heavy metal excess, which is conserved in human cells. In summary, our results suggest that diphthamide contributes to the functionality of the translational machinery monitored by plants to regulate growth. Diphthamide is a post-translationally modified histidine residue present in animal and yeast TRANSLATION ELONGATION FACTOR2. Here the authors show that diphthamide modification of eEF2 is conserved in Arabidopsis thaliana and contributes to translational fidelity and growth via cell proliferation.

N-terminal protein acetylation (NTA) is a prevalent protein modification essential for viability in animals and plants. The dominant executor of NTA is the ribosome tethered Nαript>-acetyltransferase A (NatA) complex. However, the impact of NatA on protein fate is still enigmatic. Here, we demonstrate that depletion of NatA activity leads to a 4-fold increase in global protein turnover via the ubiquitin-proteasome system in Arabidopsis. Surprisingly, a concomitant increase in translation, actioned via enhanced Target-of-Rapamycin activity, is also observed, implying that defective NTA triggers feedback mechanisms to maintain steady-state protein abundance. Quantitative analysis of the proteome, the translatome, and the ubiquitome reveals that NatA substrates account for the bulk of this enhanced turnover. A targeted analysis of NatA substrate stability uncovers that NTA absence triggers protein destabilization via a previously undescribed and widely conserved nonAc/N-degron in plants. Hence, the imprinting of the proteome with acetylation marks is essential for coordinating proteome stability. N-terminal protein acetylation is required for plant viability. Here the authors show that reducing N-terminal acetylation by NatA leads to an increase in global protein turnover that is facilitated by absent masking of a novel N-degron [ABSTRACT FROM AUTHOR] more...

Rice grains typically contain high levels of toxic arsenic but low levels of the essential micronutrient selenium. Anthropogenic arsenic contamination of paddy soils exacerbates arsenic toxicity in rice crops resulting in substantial yield losses. Here, we report the identification of the gain-of-function arsenite tolerant 1 (astol1) mutant of rice that benefits from enhanced sulfur and selenium assimilation, arsenic tolerance, and decreased arsenic accumulation in grains. The astol1 mutation promotes the physical interaction of the chloroplast-localized O-acetylserine (thiol) lyase protein with its interaction partner serine-acetyltransferase in the cysteine synthase complex. Activation of the serine-acetyltransferase in this complex promotes the uptake of sulfate and selenium and enhances the production of cysteine, glutathione, and phytochelatins, resulting in increased tolerance and decreased translocation of arsenic to grains. Our findings uncover the pivotal sensing-function of the cysteine synthase complex in plastids for optimizing stress resilience and grain quality by regulating a fundamental macronutrient assimilation pathway. Contamination of paddy soils can lead to toxic arsenic accumulation in rice grains and low levels of the micronutrient selenium. Here the authors show that a gain of function mutant affecting an O-acetylserine (thiol) lyase enhances sulfur and selenium assimilation while reducing arsenic accumulation in grains.

Protein acetylation is a highly frequent protein modification. However, comparatively little is known about its enzymatic machinery. N‐α‐acetylation (NTA) and ε‐lysine acetylation (KA) are known to be catalyzed by distinct families of enzymes (NATs and KATs, respectively), although the possibility that the same GCN5‐related N‐acetyltransferase (GNAT) can perform both functions has been debated. Here, we discovered a new family of plastid‐localized GNATs, which possess a dual specificity. All characterized GNAT family members display a number of unique features. Quantitative mass spectrometry analyses revealed that these enzymes exhibit both distinct KA and relaxed NTA specificities. Furthermore, inactivation of GNAT2 leads to significant NTA or KA decreases of several plastid proteins, while proteins of other compartments were unaffected. The data indicate that these enzymes have specific protein targets and likely display partly redundant selectivity, increasing the robustness of the acetylation process in vivo. In summary, this study revealed a new layer of complexity in the machinery controlling this prevalent modification and suggests that other eukaryotic GNATs may also possess these previously underappreciated broader enzymatic activities. Synopsis: A novel protein acetyltransferase family localized or associated to plant plastids is identified and characterised. These GCN5‐related N‐acetyltransferases (GNATs) have unique amino acid sequence characteristics and unambiguously possess dual N‐α‐ and ε‐lysine acetylation activities. An in silico search for putative plastidial N‐terminal and lysine acetyltransferases reveals 10 putative GNAT candidates, showing unique features both at the level of the conserved motifs and key residues.Localization to chloroplasts is confirmed for seven of them, while another one is either associated to chloroplasts or localized within the nucleus.All plastid‐associated GNATs display distinct lysine acetyltransferase and relaxed N‐ terminal acetyltransferase substrate specificities.Inactivation of GNAT2, the plastid GNAT involved in photosynthetic state transitions, results in NTA decreases confined to chloroplast proteins, next to the known decreases on photosynthetic KA target proteins.

Purpose: The aim of the study was to evaluate an outpatient psychoeducational group program for breast cancer patients aimed to improve various psychosocial parameters, enhancing the patients' competence and reducing fear of recurrence. Methods: The study is based on a multi-center, non-randomized control group design with three measurement time points (T1 baseline, T2 end of the intervention, T3 6-week follow-up). Breast cancer patients were assessed with various standardized questionnaires including fear of progression, self-efficacy, depression, and quality of life. Results: A total of 50 breast cancer patients participated (intervention group n = 27, control group n = 23). The results show a significant reduction in the fear of progression/recurrence (FoPR) (p = 0.003) and a significant increase in self-efficacy (SE) (p = 0.007) for the intervention group with a large (FoPR, Eta2 =.178) and medium (SE, Eta2 =.113) effect size, respectively. For all other outcome criteria such as depressive symptoms, social support, or quality of life, no significant changes over time or differences between both groups were found. Conclusions: The psychoeducational program has been proven to be effective for breast cancer survivors, but further investigation based on a randomized trial is necessary. Practice implications: To improve participation rate assessment of patient's needs and close cooperation with rehabilitation centers, psychosocial counseling services, and medical oncologists are recommended.

Growth of eukaryotic cells is regulated by the target of rapamycin (TOR). The strongest activator of TOR in metazoa is amino acid availability. The established transducers of amino acid sensing to TOR in metazoa are absent in plants. Hence, a fundamental question is how amino acid sensing is achieved in photo-autotrophic organisms. Here we demonstrate that the plant Arabidopsis does not sense the sulfur-containing amino acid cysteine itself, but its biosynthetic precursors. We identify the kinase GCN2 as a sensor of the carbon/nitrogen precursor availability, whereas limitation of the sulfur precursor is transduced to TOR by downregulation of glucose metabolism. The downregulated TOR activity caused decreased translation, lowered meristematic activity, and elevated autophagy. Our results uncover a plant-specific adaptation of TOR function. In concert with GCN2, TOR allows photo-autotrophic eukaryotes to coordinate the fluxes of carbon, nitrogen, and sulfur for efficient cysteine biosynthesis under varying external nutrient supply.

In cancer care, where patients and their families experience significant emotional distress and patients have to deal with complex medical information, patient centeredness is an important aspect of quality of care. The aim of this study is to examine the impact of patients' trust in their oncologists and patients' enablement on changes in health-related quality of life of colon cancer patients during follow-up care. We conducted a prospective study in a representative sample of private practices of German oncologists (N = 44). Patients (N = 131) filled out a standardized questionnaire prior to their first consultation (T0), directly after the first consultation (T1) and after two months (T2). Data were analyzed by structural equation modeling. Significant associations were found between trust in physician and changes in physical functioning between T1 and T2, and between trust in physician and patient enablement. Patient enablement is significantly associated with changes in physical functioning between T1 and T2. The results underline the importance of building a close and trustful patient-physician relationship in the oncology encounter. A central mechanism of the association between the quality of the relationship and health outcomes seems to be patient enablement. To enable patients to cope with their situation by making them understand their diagnosis, treatments, and side effects can impact health-related quality of life in physical domains.

Purpose: After a short hospital stay of just some days follows long-term outpatient care for breast cancer patients. The aim of the study is to describe the information needs of breast cancer outpatients and to get in touch with aspects of health literacy, as well as contact various health care workers.Methods: In a multicenter study, patients were asked about their information needs 10 weeks after surgery. The analysis on hand includes data about 1248 female patients. In addition to descriptive analyses identifying the most prevalent information needs, logistic regression analyses were calculated to identify factors associated with these.Results: The results show that information needs of breast cancer outpatients are mainly in "follow-up after acute treatment", "coping with long-term side effects", and "heredity of breast cancer". In addition to sociodemographic patient characteristics, perceived helpful contacts with various health care workers as well as a satisfactory patient's level of health literacy reduced the probability of unmet information needs.Conclusions: Breast cancer outpatients have numerous information needs. In addition to provide information at the right time regarding a specific disease phase, it is important that health professionals' support affected breast cancer patients in coping with the new situation.

In the subject matter of functional relationships, a student's ability to translate from one form of representation to another is seen as a central competence. In the course of the HEUREKO project (heuristic work with representations of functional relationships and the diagnosis of mathematical competencies of students), a theoretical competence structure model comprising five competence dimensions was developed. These are based on four types of representation (graph, numerical table, algebraic equation and situational description) and correspond to the skill to translate from one type of representation to another. The following study was aimed to examine the facets of the model. The 5-dimensional model was empirically tested with a sample of N = 645 students of grades 9 and 10. This was accomplished by comparing competing item response models with regard to model fit using information criteria measures. In comparison with other possible model structures, our postulated 5-dimensional model showed the best model fit, suggesting that all translations are relevant for competence assessment and development. Furthermore, in order to allow for the identification of structural components of cognitive actions, the employed tasks used in the empirical testing were divided into categories with regard to the different demands of cognitive action. Our results suggest that cognitive actions may have a specific dimensional structure. These findings can contribute to a better diagnostic approach concerning specific strengths and weaknesses and can therefore foster students' competencies. [ABSTRACT FROM AUTHOR] more...

Purpose: A common phenomenon among cancer patients is a fear of cancer recurrence or cancer progression (FOP). The aim of the present study was to analyze whether the oncologist is able to reduce patients' FOP at the initial clinical interview.Method: A prospective, longitudinal study included patients who were consulting private-practice oncologists in Germany for the first time. Recruitment was carried out by 44 members of the Professional Organization of Office-Based Hematologists and Oncologists. In the patient surveys, data on colon cancer patients' perceptions of communications with their oncologist and on patient-reported outcomes were collected over a period of 6 months. The present study analyzed the patients' data before their first consultation (T 0) and within 3 days after the first consultation (T 1).Results: A total of 169 patients agreed to participate in the study. Backwards multiple regression analysis was conducted to determine whether the change (T 0-T 1) in FOP is associated with demographic, medical, or psychosocial determinants, or with the physician-patient communication. A significant association was found between the change in FOP and interruptions to the conversation, the comprehensibility of the information provided, the extent of perceived empathy from the physician, and the patient's social support and family status.Conclusion: Private social support and the initial medical encounter can help reduce FOP. Particularly, oncologists should ensure that they facilitate the presentation of information in a comprehensible way while avoiding interruptions and that they take particular care of patients with poor social support.

Purpose This study aimed to develop a self-description assessment instrument to measure work performance in patients with musculoskeletal diseases. In terms of the International Classification of Functioning, Disability and Health (ICF), work performance is defined as the degree of meeting the work demands (activities) at the actual workplace (environment). To account for the fact that work performance depends on the work demands of the job, we strived to develop item banks that allow a flexible use of item subgroups depending on the specific work demands of the patients' jobs. Methods Item development included the collection of work tasks from literature and content validation through expert surveys and patient interviews. The resulting 122 items were answered by 621 patients with musculoskeletal diseases. Exploratory factor analysis to ascertain dimensionality and Rasch analysis (partial credit model) for each of the resulting dimensions were performed. Results Exploratory factor analysis resulted in four dimensions, and subsequent Rasch analysis led to the following item banks: 'impaired productivity' (15 items), 'impaired cognitive performance' (18), 'impaired coping with stress' (13) and 'impaired physical performance' (low physical workload 20 items, high physical workload 10 items). The item banks exhibited person separation indices (reliability) between 0.89 and 0.96. Conclusions The assessment of work performance adds the activities component to the more commonly employed participation component of the ICF-model. The four item banks can be adapted to specific jobs where necessary without losing comparability of person measures, as the item banks are based on Rasch analysis. [ABSTRACT FROM AUTHOR] more...

Background: Depression in cardiac patients has gained importance due to increased mortality. Although sleep disturbances are a core symptom of depression, the prevalence and patterns of sleep disturbances in heart disease have hardly been examined regarding depression. Purpose: This cross-sectional study aims to examine sleep disturbances and depressive symptoms in consecutively admitted cardiac patients and depressed patients. Methods: Two hundred four inpatients (113 male, 91 female) were examined: 94 cardiac inpatients (mean age 49.3 ± 14.3 years) with different heart diseases and 110 psychiatric inpatients (mean age 41.6 ± 13.0 years) with depressive disorders (DP). A depressive episode according to International Classification of Diseases (ICD)-10 was also diagnosed in 14 of the cardiac patients (DCP). The Pittsburgh Sleep Quality Index (PSQI) and the Beck Depression Inventory (BDI) were used to assess subjective sleep quality and severity of depressive symptoms. Results: Poor sleep quality (PSQI > 5) was reported in all comorbid DCP (PSQI 12.00 ± 3.53, BDI 17.86 ± 4.28), in 60% of the 80 non-DCP (PSQI 5.59 ± 3.73, BDI 4.47 ± 3.07), and in 86.4% of the DP (PSQI 11.76 ± 4.77, BDI 27.11 ± 10.54). The cardiac inpatients showed a significant correlation between increased depressive symptoms and the PSQI components subjective sleep quality ( r = 0.40) and daytime dysfunction ( r = 0.34). Both sleep components were significant predictors of self-rated depression ( R² = 0.404). Conclusions: Most cardiac patients experience poor sleep quality. Self-reported sleep disturbances in heart disease could serve as predictors of clinical or subclinical comorbid depression outside of a psychiatric setting in cardiology and other fields, and such patients should be referred to consultation-liaison psychiatry or polysomnography where sleep disorders like sleep apnea are suspected.

In the vascular plant Arabidopsis thaliana, synthesis of cysteine and its precursors O-acetylserine and sulfide is distributed between the cytosol, chloroplasts, and mitochondria. This compartmentation contributes to regulation of cysteine synthesis. In contrast to Arabidopsis, cysteine synthesis is exclusively restricted to chloroplasts in the unicellular green alga Chlamydomonas reinhardtii. Thus, the question arises, whether specification of compartmentation was driven by multicellularity and specified organs and tissues. The moss Physcomitrella patens colonizes land but is still characterized by a simple morphology compared to vascular plants. It was therefore used as model organism to study evolution of compartmented cysteine synthesis. The presence of O-acetylserine(thiol)lyase (OAS-TL) proteins, which catalyze the final step of cysteine synthesis, in different compartments was applied as criterion. Purification and characterization of native OAS-TL proteins demonstrated the presence of five OAS-TL protein species encoded by two genes in Physcomitrella. At least one of the gene products is dual targeted to plastids and cytosol, as shown by combination of GFP fusion localization studies, purification of chloroplasts, and identification of N termini from native proteins. The bulk of OAS-TL protein is targeted to plastids, whereas there is no evidence for a mitochondrial OAS-TL isoform and only a minor part of OAS-TL protein is localized in the cytosol. This demonstrates that subcellular diversification of cysteine synthesis is already initialized in Physcomitrella but appears to gain relevance later during evolution of vascular plants.

Purpose: Understanding how the information needs of cancer patients (CaPts) vary is important because met information needs affect health outcomes and CaPts' satisfaction. The goals of the study were to identify subgroups of CaPts based on self-reported cancer- and treatment-related information needs and to determine whether subgroups could be predicted on the basis of selected sociodemographic, clinical and clinician-patient relationship variables.Methods: Three hundred twenty-three CaPts participated in a survey using the "Cancer Patients Information Needs" scale, which is a new tool for measuring cancer-related information needs. The number of information need subgroups and need profiles within each subgroup was identified using latent class analysis (LCA). Multinomial logistic regression was applied to predict class membership.Results: LCA identified a model of five subgroups exhibiting differences in type and extent of CaPts' unmet information needs: a subgroup with "no unmet needs" (31.4% of the sample), two subgroups with "high level of psychosocial unmet information needs" (27.0% and 12.0%), a subgroup with "high level of purely medical unmet information needs" (16.0%) and a subgroup with "high level of medical and psychosocial unmet information needs" (13.6%). An assessment of sociodemographic and clinical characteristics revealed that younger CaPts and CaPts' requiring psychological support seem to belong to subgroups with a higher level of unmet information needs. However, the most significant predictor for the subgroups with unmet information needs is a good clinician-patient relationship, i.e. subjective perception of high level of trust in and caring attention from nurses together with high degree of physician empathy seems to be predictive for inclusion in the subgroup with no unmet information needs.Conclusions: The results of our study can be used by oncology nurses and physicians to increase their awareness of the complexity and heterogeneity of information needs among CaPts and of clinically significant subgroups of CaPts. Moreover, regression analyses indicate the following association: Nurses and physicians seem to be able to reduce CaPts' unmet information needs by establishing a relationship with the patient, which is trusting, caring and empathic.

Biosynthesis of cysteine is a two-step process in higher plants subsequently catalyzed by serine acetyltransferase (SAT) and O-acetylserine (thiol) lyase (OAS-TL) which are present in cytosol, plastids and mitochondria. Recently, the distribution of SAT and OAS-TL in these subcellular compartments was shown to be crucial for efficient cysteine synthesis in Arabidopsis thaliana. In this study, the abundances of OAS-TLs were quantified independently by immunological detection in crude protein extracts and by SAT affinity purification (SAP) of OAS-TL. OAS-TL A and B were evidenced to be the most abundant isoforms in all analyzed tissues, which is consistent with micro array-based transcript analyses. Application of SAP to Arabidopsis revealed significant modification of the major OAS-TL isoforms present in cytosol, plastids and mitochondria into up to seven subspecies. Specific OAS-TL isoforms were found to be differentially modified in the leaves, roots, stem and cell culture. Sulphur deficiency did not alter modification of OAS-TL proteins purified from cell culture that showed the highest complexity of OAS-TL modifications. However, the pattern of OAS-TL modification was found to be stable within an analyzed tissue, pointing not only to a high reproducibility of SAP but likely biological significance of each subspecies. The most abundant OAS-TL subspecies in cytosol and plastids were subject of N-terminal processing followed by acetylation of the newly originated N-terminus. The mode of N-terminal acetylation of OAS-TL and its possible biological function are discussed. [ABSTRACT FROM AUTHOR] more...

Purpose: The present explorative study was designed as a qualitative evaluation of the psycho-oncology services (POS) available at a psycho-oncology institution (POI) in Germany. The study focused on barriers to using these services.Methods: Seven focus groups and five complementary individual interviews were conducted with POS users, their relatives, and POS non-users from a German POI, as well as with oncology physicians and nurses from an affiliated hospital. The focus groups and individual interviews were audiotaped and fully transcribed. Data were analyzed using the documentary method.Results: Four utilization barriers were identified: (1) patients' and physicians' information deficits about POI and POS, (2) patients' and physicians' subjective norms regarding POS, (3) lack of organizational and therapeutic integration of POI and POS into routine oncology care on the ward, and (4) specific characteristics of cancer patients. The most important finding was that lack of organizational and therapeutic integration of POS in routine oncology care on the ward might have a lasting, negative effect on patients' and physicians' information deficits and subjective norms. Furthermore, the identified utilization barriers seem to be a multi-causal problem with complex interdependencies.Conclusion: Based on these results, the organizational and therapeutic integration of POS in routine oncology care on the POI ward appears to be a useful tool in offering widely accessible therapies and providing patients with concise, straightforward information via different channels, such as personnel, brochures, and the Internet. Nevertheless, the results should be interpreted tentatively, due to the explorative character of this study. [ABSTRACT FROM AUTHOR] more...

Aim: Research on life circumstances, quality of life (QOL) and coping behavior in mothers with multiple sclerosis (MS).Method: Anonymous standardised questionnaire sent to 7,050 members of a section of the German MS Association (response rate 44.8%). Comparison of 482 mothers with MS (children aged < 18 years) with 607 childless women with MS.Results: No statistically significant differences concerning age, MS course, complaints or number of exacerbations. Mothers with MS more frequently had a relationship, a higher monthly net income, were less employed, EDSS-score was lower and disease duration shorter. In QOL mothers with MS showed better social aspects even after multivariate adjustment for sociodemographic and disease-related variables. Influencing parameters on the social area of QOL were employment status, age, monthly household net income and disability. In their coping behavior mothers tended more to "religiosity/search for sense in life".Conclusion: There were several differences in sociodemographic data, QOL and coping behavior factors between mothers and childless women with MS. However, if motherhood itself has an influence on QOL and coping can not be derived from our data but there are some hints that motherhood seems to be no potential problem for living with the disease. Further research upon this topic is needed. [ABSTRACT FROM AUTHOR] more...

A growing interest has been focusing on the relationship between religious coping and psychosocial adjustment among cancer patients. However, previous research mostly has not differentiated between positive and negative components of religious coping. The current cross-sectional study investigated the role of both positive religious coping, i.e., a confident and constructive turning to religion, and negative religious coping, i.e., religious struggle and doubt, in a sample of 156 German breast cancer patients. Participants were assessed upon admission to an inpatient rehabilitation program. In addition to religious coping, two basic nonreligious coping styles (depressive coping and active problem-focused coping) and psychosocial adjustment (anxiety and depression) were measured. Major research questions concerning the mediating role of nonreligious coping and the relative predictive power of positive and negative religious coping were primarily addressed using structural equation modeling. Results indicated that the relationship between religious coping and psychosocial outcomes was completely mediated by nonreligious coping, whereby only depressive coping and not active problem-focused coping proved to be a mediating variable. Positive and negative religious coping were somewhat positively related to each other; their (indirect) predictive power on psychosocial adjustment was identical though in an opposite direction. All in all, the results correspond to previous Anglo-American research. There are, however, some discrepancies which may be due to the specific religious-cultural background in Germany.

The treatment of Arabidopsis thaliana with methyl jasmonate was used to investigate the reaction of 2467 selected genes of primary and secondary metabolism by macroarray hybridization. Hierarchical cluster analysis allowed distinctions to be made between diurnally and methyl jasmonate regulated genes in a time course from 30 min to 24 h. 97 and 64 genes were identified that were up- or down-regulated more than 2-fold by methyl jasmonate, respectively. These genes belong to 18 functional categories of which sulfur-related genes were by far strongest affected. Gene expression and metabolite patterns of sulfur metabolism were analysed in detail, since numerous defense compounds contain oxidized or reduced sulfur. Genes encoding key reactions of sulfate reduction as well as of cysteine, methionine and glutathione synthesis were rapidly up-regulated, but none of the known sulfur-deficiency induced sulfate transporter genes. In addition, increased expression of genes of sulfur-rich defense proteins and of enzymes involved in glucosinolate metabolism was observed. In contrast, profiling of primary and secondary sulfur metabolites revealed only an increase in the indole glucosinolate glucobrassicin upon methyl jasmonate treatment. The observed rapid mRNA changes were thus regulated by a signal independent of the known sulfur deficiency response. These results document for the first time how comprehensively the regulation of sulfur-related genes and plant defense are connected. This interaction is discussed as a new approach to differentiate between supply- and demand-driven regulation of the sulfate assimilation pathway. [ABSTRACT FROM AUTHOR] more...

This review will assess new features reported for the molecular and biochemical aspects of cysteine and methionine biosynthesis in Arabidopsis thaliana with regards to early published data from other taxa including crop plants and bacteria ( Escherichia coli as a model). By contrast to bacteria and fungi, plant cells present a complex organization, in which the sulfur network takes place in multiple sites. Particularly, the impact of sulfur amino-acid biosynthesis compartmentalization will be addressed in respect to localization of sulfur reduction. To this end, the review will focus on regulation of sulfate reduction by synthesis of cysteine through the cysteine synthase complex and the synthesis of methionine and its derivatives. Finally, regulatory aspects of sulfur amino-acid biosynthesis will be explored with regards to interlacing processes such as photosynthesis, carbon and nitrogen assimilation.
