Grapevine trunk diseases have devastating consequences on vineyards worldwide. European wild grapevines (Vitis vinifera subs. sylvestris) from the last viable population in Germany along the Rhine river showed variable degrees of resistance against Neofusicoccum parvum (strain Bt‐67), a fungus associated with Botryosphaeriaceae‐related dieback. - Representative genotypes from different subclades of this population were mapped with respect to their ability to induce wood necrosis, as well as their defence responses in a controlled inoculation system. - The difference in colonization patterns could be confirmed by cryo‐scanning electron microscopy, while there was no relationship between vessel diameter and infection success. Resistant lines accumulated more stilbenes, that were in addition significantly partitioned to nonglycosylated viniferin trimers. By contrast, the susceptible genotypes accumulated less stilbenes with a significantly higher proportion of glycosylated piceid. - We suggest a model in which in the resistant genotypes phenylpropanoid metabolism is channelled rapidly and specifically to the bioactive stilbenes. Our study specifies a resistant chemotype against grapevines trunk diseases and paves a way to breed for resistance against grapevine Botryosphaeriaceae‐related dieback.

Chromoblastomycosis (CBM) is a chronic fungal infection of the skin and subcutaneous tissue caused by dematiaceous fungi. CBM lesions are recalcitrant and extremely difficult to eradicate. We report three cases of CBM with difficulties in therapeutic management.Three men aged 36, 50 and 67 years, all farmers, presented for between three and ten years with hyperkeratotic, scaly plaques with black dots on the right thigh and left leg, respectively. For all patients, mycological examination showed fumagoid cells, all of which were pathognomonic for CBM. PCR identified Fonsecaeanubica in one patient and Cladophialophoracarrionii in two patients. All patients received itraconazole 200mg/day for over 18 months. Two patients required combined therapy with terbinafine for seven months, which improved lesions; however, relapse occurred in one patient during the 5th month of this combined therapy and five months after the end of this treatment in the other. The patient on monotherapy (itraconazole) also presented recurrence of lesions five months after the end of treatment.Itraconazole is the standard therapy for CBM, with cure rates ranging from 15 to 80%. Success with itraconazole after eight to twelve months was reported by several authors. Fonsecaea and Cladophialophora are the most common species found in Madagascar, and while these organisms are susceptible to triazoles in vitro, clinical response is not so clear-cut.Although unavailable in Madagascar, posaconazole and isavoconazole appear to be effective in treating chromoblastomycosis.

L'étude de la structure génétique des populations d'une espèce à partir de données génomiques permet de comprendre son évolution, l'histoire de la propagation des individus, ses modes de reproduction ou les échanges de matériel génétique entre populations. Dans le cas d'espèces de microorganismes pathogènes, caractériser la structure et en comprendre les causes peut apporter des connaissances cruciales pour la gestion des épidémies ou la prédiction de leur évolution. Le champignon ascomycète Pyricularia oryzae infecte de nombreuses espèces de poacées et est responsable à lui seul de plus de 4% de perte de rendement sur la production mondiale de riz. En 1985, un saut d'hôte a entrainé l'émergence de la pyriculariose du blé. Les épidémies sur cette céréale restaient circonscrites à l'Amérique du sud mais ont émergés très récemment en Asie. L'étude de 81 génomes de P. oryzae prélevés de différentes espèces de poacées a confirmé l'existence de lignées hôte-spécifiques. Parmi celles-ci, la lignée Oryza (pathogène du riz) au sein de laquelle des groupes génétiques différenciés ont également été mis en évidence. Cependant, les facteurs impliqués dans cette différenciation ne sont pas connus. Ce travail de thèse porte sur l'étude de la structure des populations au sein de P. oryzae et avait deux objectifs principaux : i) mettre en évidence des polymorphismes spécifiques de la lignée Triticum responsable des épidémies de pyriculariose du blé afin de développer des outils de diagnostic essentiels pour éviter l'introduction de l'agent pathogène dans des régions encore indemnes de cette maladie ; ii) Affiner nos connaissances sur les lignées existantes au sein de la lignée Oryza et déterminer les facteurs responsables de cette structure génétique. La propagation sur de longue distance de la pyriculariose du blé est rendu possible par le transport de matériel biologique contaminé, comme les semences. La mise au point de méthodes de détection fiables de l'agent pathogène est donc cruciale pour éviter son importation dans de nouvelles régions. La structure en lignée hôte spécifique précédemment établie à mis en évidence la lignée Triticum regroupant les isolats responsables des épidémies de pyriculariose du blé. Une approche de comparaison de génomes développée au cours de cette thèse a permis d'identifier de multiples allèles spécifiques de la lignée Triticum. Ces allèles ont été ciblés pour le développement de tests moléculaires de détection utilisant plusieurs techniques d'amplification. Des tests de PCR conventionnelle, de PCR en temps-réel et LAMP (amplification isothermale) ciblant plusieurs régions génomiques ont été développés et améliorent la détection de l'agent pathogène. L'application de ces tests à la détection sur des semences infectées a également été vérifiée. Afin de préciser la structure des populations au sein de la lignée infectant le riz (lignée Oryza) et d'améliorer nos connaissances sur son histoire évolutive un jeu de données de 5000 SNPs caractérisés chez 900 isolats couvrant l'aire de répartition de l'agent pathogène a été analysé. Nos analyses mettent en évidence quatre lignées majeures, dont deux lignées clonales pandémiques, une lignée clonale essentiellement Sud-Asiatique, et une lignée recombinante fréquente en Asie du Sud-Est. La lignée recombinante présente de plus une sous-structure géographique. Les barrières aux flux gènes permettant le maintien de cette structure génétique ont été recherchées. Une forte corrélation entre aire de répartition des lignées et données climatiques a été mise en évidence. Des adaptations différentielles de ces lignées à des facteurs environnementaux (température et plante hôte) ont ensuite été évaluées identifiant des différences de largeur de spectres d'hôte entre lignées. De fortes barrières à la reproduction ont également été révélées, ainsi qu'une perte de fertilité dans certaines lignées, limitant le flux de gènes entre ces lignées

Chromomycosis is a chronic fungal skin infection, mainly affecting the limbs. It is responsible for severe morbidity and its treatment remains long and disappointing. Rarely described in Morocco, we report a new observation that has evolved very well under treatment combining terbinafine and cryotherapy over a short duration.A 56-year-old patient, immunocompetent, had a pustular and crusty placard on both forearms that had evolved for a year. Mycological examination showed fumagoid bodies and cutaneous biopsy showed epithelioid granulomas and giant cells without necrosis. The PCR confirmed a chromomycosis at Fonsecaea pedrosoi. HIV serology was negative. Treatment with terbinafine 250mg/d for 6months combined to cryotherapy resulted in complete remission with initial clinical improvement after only 3 weeks.Chromomycosis occurs increasingly in non-tropical areas. If diagnostic methods become more effective, management remains difficult and poorly codified. Terbinafine-cryotherapy combination would bring a lot of benefits with a little risk to bothpractitioner and patient.This combined treatment would constitute an excellent therapeutic alternative because of its efficiency, feasibility, low cost, method of administration and aesthetic result.

The cork oak forest is an ecosystem playing a major role in Moroccan socio-economy and biodiversity conservation. However, this ecosystem is negatively impacted by extensive human- and climate-driven pressures, causing a strong decrease in its distribution and a worsening of the desertification processes. This study aims at characterising the impact of cork oak forest management on a major actor of its functioning, the ectomycorrhizal (EcM) fungal community associated with Quercus suber, and the determination of EcM bio-indicators. The EcM fungal community has been monitored during spring and winter seasons in two sites of the Moroccan Mâamora forest, corresponding to a forest site either impacted by human activities or protected. A significant impact of cork oak forest management on the EcM fungal community has been revealed, with major differences during the summer season. The results confirmed the potential ecological significance of several EcM fungi (e.g., Cenococcum) in the sustainability of the cork oak forest functioning, but also the significant association of certain EcM fungi (Pachyphloeus, Russula, Tomentella) with a perturbation or a season, and consequently to the cork oak forest status or to climatic conditions, respectively. The development of study at the Mediterranean scale may improve the robustness of ecological models to predict the impact of global changes on this emblematic ecosystem of Mediterranean basin.

Chromomycosis, or chromoblastomycosis, is caused by cutaneous inoculation of dematiaceous fungi of telluric or plant origin. It is generally seen in tropical or subtropical zones. Treatment of the condition is known to be complex. Herein we report a case of chromomycosis contracted in a temperate region of Eastern Europe/Central Asia that was effectively treated with oral itraconazole and terbinafine in combination with cryotherapy.A 44-year-old immunocompetent male subject consulted for a lesion on the buttocks that he had sustained 16 years earlier, and which, although never previously treated, had only become troublesome within the last few months. The examination revealed a large erythemato-squamous plaque containing a heterogeneous infiltrate. The diagnosis was based upon biopsy, with histological examination revealing sooty mould ; culture of a second sample showed the causative agent to be Fonsecaea pedrosoi. After 30 months of treatment combining oral terbinafine at a very high dose (1000mg/day), topical terbinafine and adjuvant cryotherapy, considerable, though incomplete, improvement was obtained. Finally, combined use of terbinafine (500mg/day) and itraconazole (200mg/day) led to clinical and histological cure.The possibility of acquiring chromomycosis other than in a tropical zone is slight but has nevertheless been described, particularly in Eastern Europe. In our patient, the exact source of contamination is unknown, although it may have been acquired through frequent horse-riding or use of saunas. This case confirms the efficacy of combined itraconazole and terbinafine against this condition, which is usually difficult to treat.

We report the case of a 13-year old female patient from rural areas presenting with papulonodular lesion of 4/3cm in the lower third of the right leg, evolving over the last two years. Skin biopsy showed papillomatous hyperplasia with neutrophilic microabscess and spores. Direct mycological examination showed fumagoid bodies and Fonsecaea pedrosoi was isolated from culture. The patient underwent medico-surgical treatment (terbinafine 250mg/day for 6 months + resection and then skin graft) with good evolution and a follow-up period of 2 years without recurrences. Chromoblastomycosis is a chronic fungal skin infection, common in tropical and subtropical areas and rare in North Africa. In Morocco, only seven cases have been reported in the literature until June 2014. It is contracted from inoculation of germ after contact with the soil or organic matters. Responsible officers are pigmented fungi belonging to the dematiated group. Given its rarity, it can mimic other dermatoses such as leishmaniasis or tuberculosis. Despite the rarity of this infection, clinicians should suspect it in patients with chronic skin lesions (verrucous, vegetative, nodular and grouped in patches), especially if they occur in areas exposed to potential plant injuries, such as the lower limbs. Mycological examination is necessary to confirm the diagnosis. Surgery or the association between surgery and systemic antifungal drugs are the treatments of choice because antifungal drugs alone may result in resistances or recurrences.

Phytopathogenic fungi are a major threat for global food security and show an extreme plasticity in pathogenicity behaviours. They often have a high adaptive potential allowing them to rapidly counteract the control methods used by men in agrosystems. In this paper, we evaluate the link between genome plasticity and adaptive potential using genomics and comparative genomics approaches. Our model is the evolutionary series Leptosphaeria maculans-Leptosphaeria biglobosa, encompassing five distinct entities, whose conspecificity or heterospecificity status is unclear, and which all are pathogens of cruciferous plants. They however differ by their host range and pathogenicity. Compared to other species of the species complex, the species best adapted to oilseed rape, L. maculans "brassicae", causing important losses in the crop, has a genome that was submitted to a recent and massive burst of transposition by a few families of transposable elements (TEs). Whether the genome invasion contributed to speciation is still unclear to-date but there is a coincidence between this burst of TEs and divergence between two species. This TE burst contributed to diversification of effector proteins and thus to generation of novel pathogenic specificities. In addition, the location of effector genes within genome regions enriched in TEs has direct consequences on adaptation to plant resistance and favours a multiplicity of mutation events allowing "breakdown" of resistance. These data are substantiated by other examples in the literature showing that fungi tend to have a "two-speed" genome, in which a plastic compartment enriched in TE host genes is involved in pathogenicity and adaptation to host.

Truffles ascocarps need carbon to grow, but it is not known whether this carbon comes directly from the tree (heterotrophy) or from soil organic matter (saprotrophy). The objective of this work was to investigate the heterotrophic side of the ascocarp nutrition by assessing the allocation of carbon by the host to Tuber melanosporum mycorrhizas and ascocarps. In 2010, a single hazel tree selected for its high truffle (Tuber melanosporum) production and situated in the west part of the Vosges, France, was labeled with (13)CO2. The transfer of (13)C from the leaves to the fine roots and T. melanosporum mycorrhizas was very slow compared with the results found in the literature for herbaceous plants or other tree species. The fine roots primarily acted as a carbon conduit; they accumulated little (13)C and transferred it slowly to the mycorrhizas. The mycorrhizas first formed a carbon sink and accumulated (13)C prior to ascocarp development. Then, the mycorrhizas transferred (13)C to the ascocarps to provide constitutive carbon (1.7 mg of (13)C per day). The ascocarps accumulated host carbon until reaching complete maturity, 200 days after the first labeling and 150 days after the second labeling event. This role of the Tuber ascocarps as a carbon sink occurred several months after the end of carbon assimilation by the host and at low temperature. This finding suggests that carbon allocated to the ascocarps during winter was provided by reserve compounds stored in the wood and hydrolyzed during a period of frost. Almost all of the constitutive carbon allocated to the truffles (1% of the total carbon assimilated by the tree during the growing season) came from the host.

A contribution to a check-list of Pezizales (Fungi, Ascomycota) in the Lyon area (France). 1st part : location, habitat, records, synopsis. - A check-list of fungi belonging to the order Pezizales (Ascomycota), commonly called Cup-fungi, is now proposed for the French department Rhône. It is based both on past data, gathered mainly by Dr Philibert Riel in the late 19th century, and on data gathered by the author who, for the past fifteen years or so, has regularly been prospecting the area around Lyon in search of Discomycetes. The author starts by describing the locations prospected, goes on to specify the historical context in which the data were gathered, then attempts to put it into perspective by using reference periods, during some of which the fungi were considered an important part of the local natural heritage., Un premier inventaire des champignons appartenant à l'ordre des Pezizales (Ascomycota), communément appelés pézizes, est proposé pour le département du Rhône. Il se base à la fois sur les données anciennes, principalement recueillies par le Dr Philibert Riel à la fin du XIXe siècle, mais aussi sur les données de l'auteur qui prospecte régulièrement le Lyonnais. depuis une quinzaine d'années, à la recherche de discomycètes. Après la présentation des localités de prospection, l'auteur précise le contexte historique des données collectées, puis les met en perspective à travers les périodes de référence, y compris sur leur intérêt patrimonial., Van Vooren Nicolas.

Les bois ont longtemps été traités avec des fongicides et "impact de ces fongicides sur les sols après lessivage constitue un vrai problème écologique. Dans cette perspective nous nous proposons d'étudier des communautés fongiques de ces bois contaminés dans un but de biorémédiation. La plupart des études précédentes se sont focalisées sur la capacité de certains Basidiomycètes et de certains champignons de la pourriture blanche à dégrader ces produits biocides. Des échantillons de bois traités et témoins ont été incubés dans des containers de sols forestiers en Guyane. Deux premiers échantillonnages de ces bois et du sol des containers ont été réalisés à S mois d'écart. Une étude culturale et moléculaire a permis l'isolement et l'identification de 40 souches d'Ascomycètes qui sont capables de se développer sur le bois et de résister à des xénobiotiques. D'autre part, une étude des communautés fongiques du bois et du sol a été effectuée par D-HPLC et CE-SSCP puis analysée par ACP. D'après ces analyses les produits biocides sont lessivés dans le sol et ont un impact sur les communautés fongiques. Celles-ci sont en effet différentes selon le temps d'échantillonnage et selon le traitement du bois. Ces résultats intéressants sont cependant à approfondir par d'autres échantillonnages et une étude culturale plus approfondie.

Thèses sur articles, soutenue le 18 novembre Diplôme : Dr. d'Université; The aim of this work was to analyze the diversity and the dispersal of composting bioaerosol emitted during the turning of compost windrows in thermophilic phase on composting platforms. The study of the microbial diversity of aerosols emitted on five composting plants was realized by 16S and 18S rDNA molecular inventories. Two bacterial phyla Firmicutes and Actinobacteria and one fungal phylum Ascomycota dominated. A common microbial signature emerged from the five composting bioaerosols: ten microbial phylotypes (seven bacterial and three fungal) were common to at least four bioaerosols. Two have been identified in five bioaerosols: NA07 belonging to the species Saccharopolyspora rectivirgula, and representing 7% of total number of bacterial sequences, and EQ05, affiliated to Thermomyces (49% of total number of fungal sequences). A second bacterial phylotype, NC38, affiliated to the Thermoactinomycetaceae family, was selected because it was identified only in the compost biotope. qPCR systems were then designed for each phylotype. Measurements performed on industrial composting sites validated the use of these microorganisms as indicators of composting bioaerosols. The dispersal of composting bioaerosols was then characterized using the three indicators developed.; Cette étude porte sur l’identification et la dispersion des bioaérosols générés sur les plates-formes de compostage et plus précisément lors du retournement des andains en cours de fermentation. L’analyse des bioaérosols émis sur cinq plates-formes, par des inventaires moléculaires (ADNr 16S et ADNr 18S), a permis de montrer la dominance de deux phyla bactériens Firmicutes et Actinobacteria et du phylum fongique Ascomycota. En comparant la structure de la population microbienne des cinq bioaérosols, une signature a été identifiée. Dix phylotypes microbiens sont communs à au moins quatre bioaérosols. Deux sont présents dans les cinq bioaérosols : NA07 appartenant à l’espèce Saccharopolyspora rectivirgula et représentant 7% des séquences bactériennes totales et EQ07 affiliée à Thermomyces (49% des séquences fongiques). Un second phylotype bactérien, NC38, affilié à la famille des Thermoactinomycetaceae a été sélectionné du fait qu’il n’ait été identifié que dans le compost. Des systèmes de PCRq ont été développés pour quantifier ces trois indicateurs potentiels. Ces derniers ont été validés expérimentalement par des mesures sur sites industriels. Lors d’une activité de retournement, la concentration des indicateurs est supérieure à leur niveau basal dans l’air (“bruit de fond”). La dispersion des bioaérosols a ensuite été caractérisée en utilisant plusieurs méthodologies, dont les trois indicateurs conçus. Les indicateurs présentent des profils de dispersion différents d’où l’intérêt de les coupler afin d’obtenir une meilleure vision de la dispersion des bioaérosols de compostage.

National audience; La résistance MDR des champignons pathogènes existe en pharmacie et en phytopharmacie. En pharmacie c'est-à-dire dans le domaine médical, elle s'observe en pratique chez divers pathogènes fongiques appartenant aux genres Candida et Aspergillus. Elle concerne particulièrement des triazoles de type IDM. En phytopharmacie - domaine agricole - de nombreux travaux menés par M. De Waard de l'Université de Wageningen aux Pays-Bas sur Botrytis cinerea et Mycosphaerella graminicola chez des mutants de laboratoire ont montré que la résistance MDR pouvait concerner les IDM mais aussi d'autres classes de fongicides (ex: phénylpyrroles, Qql). Mais les investigations au champ n'ont démontré l'existence de ce phénomène que dans un nombre limité de cas. Trois d'entre eux ont été détectés en France chez B. cinerea, M. graminicola et Oculimacula yallundae, responsables respectivement de la pourriture grise de la vigne, de la septoriose du blé et du piétin-verse des céréales ; un cas concernant Penicillium italicum a été signalé au Japon. L'objectif de cet article est de faire le point sur la résistance de type MDR rencontrée en France.
