Abstract

The article focuses on the research conducted by the Lehr- und Versuchsanstalt für Gartenbau (LVG) Bad Zwischenahn on whether dew-colored pots are more translucent than the black pots that have been used up to now and thus could possibly have a negative effect on root and plant growth. It mentions temperature differences between the northeast and southwest sides of root. INSET: FAZIT: EFFEKTE SIND ZU VERNACHLÄSSIGEN..

21. Funktionale Analyse des PhytosulfokinRezeptors 1 aus Arabidopsis thaliana

Abstract

In Arabidopsis thaliana, the peptide growth factor phytosulfokine (PSK) is perceived by two plasma membrane-localized receptors termed PSKR1 and PSKR2 that belong to the leucine-rich repeat class of receptor kinases. In this study functional analysis in particular of PSKR1 from Arabidopsis was performed. Overexpression of PSKR1 and PSKR2 in the wild type resulted in promotion of root and hypocotyl growth showing that abundance of PSK receptors limits growth. Epidermis-specific expression of PSKR1 in the pskr1-3 pskr2-1 (r1r2) background driven by the CER6 promoter showed that perception of PSK in the epidermis is sufficient to stimulate growth not only of the outer but also of the inner cell layers. Furthermore, expression of PSKR1 driven by the atrichoblast-specific promoter GL2 in r1r2 promoted growth not only of atrichoblast cells but also of root hair-forming trichoblasts. Hence, expression of PSKR1 in one cell type of the epidermis is sufficient to stimulate whole-organ growth indicating that PSK acts as a non-cell autonomous growth factor in planta. Bioinformatic analysis identified a calmodulin (CaM)-binding site in PSKR1. Replacement of the conserved tryptophan W831 in the CaM binding site by a hydrophilic serine resulted in loss of CaM binding. Expression of the CaM binding site mutated receptor variant in r1r2 enhanced the r1r2 phenotype with reduced root and shoot growth.Expression of the kinase-inactive PSKR1(K762E) in r1r2 resulted in reduced root and shoot growth. Hence, both, PSKR1 kinase activity and CaM binding to the receptor are essential for the growth promoting effect of PSK in planta. To study the regulation of the receptor by phosphorylation, a phosphosite mapping of PSKR1 was performed in collaboration. Subsequent functional analysis of identified phosphorylation sites by site-directed mutagenesis demonstrated that three conserved threonines and one serine (T890, S893, T894 and T899) located in the activation loop of PSKR1 are required for in vitro PSKR1 kinase activity and for receptor function in planta.

Abstract

Das Wurzelwachstum von Winterweizen wurde erfasst und modelliert, um teilflächenspezifisches Boden- und Düngemanagement zu verbessern. Die Variation von Wurzellängendichten im Feld wurde über zwei Vegetationsperioden hinweg an zwei unterschiedlichen Standorten in Ostdeutschland untersucht. Zur Auswertungserleichterung der hohen Anzahl an Wurzelproben, wurde eine halbautomatische Methode zur Bildanalyse von Wurzeln entwickelt. Der Einfluss von Änderungen bezüglich Bodenwasserstatus und Bodendichte bzw. Durchdringungswiderstand auf das Wurzelwachstum wurde untersucht. Die erhobenen Felddaten dienten gleichzeitig dazu, die Bodenwasser- und Wurzelwachstumsberechnung des Modells CERES-Wheat zu validieren. Das Modell simulierte die unterschiedlichen Bodeneigenschaften sowie die Wurzellängendichten und Bodenwassergehalte nur unzureichend. Der Effekt von Änderungen der Niederschlagsmengen auf die Simulationen von Wurzellängendichten und Bodenwassergehalten wurde anhand einer Unsicherheitsanalyse getestet und war extrem gering. Des Weiteren wurde eine Methode für praktische Zwecke entwickelt, mit der die Generierung von räumlich hoch aufgelösten Bodeninformationen unter Verwendung limitierter Eingangsdaten möglich ist. Die Modellkalkulationen basieren auf der Dempster-Shafer-Theorie. Anhand von multitemporal und multimodal erfassten Bodenleitfähigkeitsdaten, die Eingangsdaten für den Modellansatz sind, wurden Bodentypen und Texturklassen bestimmt. Das Modell generiert eine digitale Bodenkarte, die flächenhafte Informationen über Bodentypen und Bodeneigenschaften enthält. Die Validation der Bodenkarte mit zusätzlich erhobenen Bodeninformationen ergab gute bis sehr gute Ergebnisse. Winter wheat root growth was measured and modelled to improve site-specific soil and fertilizer management in commercial wheat fields. Field variations in root length densities were analysed at two contrasting sites in East-Germany during two vegetation seasons. A semi-automated root analysing method was developed to facilitate analyses of large numbers of samples. Influences of variations in soil water states, bulk densities and penetration resistances on spatial distributions of roots were quantified. Differences in soil characteristics were large between the two sites and affected root growth considerably. The same field data was used for validating the soil moisture and root growth calculations of the widely applied growth model CERES-Wheat. Simulations of root length densities, soil physical properties and soil water contents were inadequate. The effects of changes of rainfall variabilities on simulated root length densities and soil water contents were tested by uncertainty analysis but were negligible low. A methodology for generating soil information for practical management purposes at a high degree of spatial resolution using limited input information was developed. The corresponding model calculations were carried out based on the Dempster and Shafer theorem. Soil types and texture classes were determined with multimodally and multitemporally captured data of soil electrical conductivities which are required input data of the new model approach. The model generates a digital map with extensive information of spatial variations in soil properties. The validation of the generated soil map with soil data from independent measurements yielded close correlation between measured and calculated values.

Abstract

Phytosulfokin-alpha (PSK-alpha) ist ein bisulfatiertes Pentapetid, welches als Wachstumsfaktor die Proliferation von Zellen in Zellkultur niedriger Dichte stimuliert. In der vorliegenden Arbeit wurden physiologische und genetische Ansätze verfolgt, um Funktionen von PSK-alpha in Arabidopsis thaliana aufzuklären. Promotor-GUS Expressionsanalysen der PSK-Präproproteingene und des PSK-Rezeptorgens AtPSKR1 in Wurzeln und Blüten deuteten auf mögliche Funktionen von PSK-alpha in diesen Geweben hin. Exogen appliziertes PSK-alpha förderte das Wurzelwachstum von Arabidopsiskeimlingen. Das Wurzelwachstum der PSK-Rezeptor T-DNA Insertionsmutante Atpskr1-T war inhibiert. Diese Ergebnisse zeigten, dass PSK-alpha in die Regulation von Wurzelwachstum involviert ist. Charakteristisch für die Atpskr1-T Mutante war eine verringerte Samenbildung im Vergleich zu Wildtyppflanzen. Genetische Analysen zeigten, dass sowohl ein paternaler als auch maternale Effekte und asynchrones Wachstum der inneren Blütenorgane zur Ausbildung des Mutantenphänotyps führen. Phytosulfokine-alpha (PSK-alpha) is a disulfated pentapeptide that was shown previously to act as growth factor in in vitro cultured plant cells kept at low density. The aim of this work was to analyse functions of PSK-alpha in planta. Arabidopsis was chosen as a model plant to perform functional analysis using both, physiological and genetic approaches. Promoter:GUS analysis revealed expression of PSK precursor genes and of the PSK receptor gene AtPSKR1 in roots and flowers. Application of PSK-alpha to growing seedlings resulted in increased root mass. On the other hand, the PSK receptor knock out mutant Atpskr1-T showed reduced growth rates confirming a role of PSK-alpha signaling in root growth regulation. The receptor knock out mutant was not only impaired in root growth but also in reproductive success. Genetic analysis indicated that paternal as well as maternal effects and asynchronous growth of the inner flower organs strongly effects seed formation in Atpskr1-T plants.
