Although the functions and structural roles of sterols have been subject numerous studies, reasons for diversity in different eukaryotic kingdoms remain unclear. It is thought that specificity linked to unidentified supplementary could enable organisms be better adapted their environment. Ergosterol accumulated by late branching fungi encounter oxidative perturbations interfacial habitats. Here, we investigated antioxidant properties ergosterol using vivo, vitro, silico approaches. The...
Summary The effects of different anthropic activities (vineyard: phytosanitary protection; winery: pressing and sulfiting) on the fungal populations grape berries were studied. global diversity (moulds yeasts) was performed by pyrosequencing. studied modified diversity. Thus, a decrease in biodiversity measured for three successive vintages grapes plot cultivated with Organic protection compared to plots treated Conventional Ecophyto protections. then considerably pressing‐clarification...
Diet quality is critical for animal development and survival. Fungi can provide nutrients that are essential to organisms unable synthetize them, such as ergosterol in Drosophila melanogaster. studies examining the influence of yeast diet have generally either provided over whole life span (larva adult) or during adult stage rarely focussed on juvenile diet. Here, we tested effect larval pre-adult weight, survival, reproduction food preference. The Saccharomyces cerevisiae was added three...
Different genera and/or species of yeasts present on grape berries, in musts and wines are widely described. Nevertheless, the community non-Saccharomyces cellar is still given little attention. Thus it not known if a real ecological niche for these or merely transient habitat populations brought by berries during winemaking period. This study focused three commonly encountered vinification: Starmerella bacillaris (synonymy with Candida zemplinina), Hanseniaspora guilliermondii uvarum. More...
In response to the presence of compatible rhizobium bacteria, legumes form symbiotic organs called nodules on their roots. These house nitrogen-fixing bacteroids that are a differentiated bacteria. some legumes, bacteroid differentiation comprises dramatic cell enlargement, polyploidization, and other morphological changes. Here, we demonstrate peptidoglycan-modifying enzyme in Bradyrhizobium strains, DD-carboxypeptidase contains peptidoglycan-binding SPOR domain, is essential for normal...
Although differences in yeast biodiversity have often been found between vineyards subjected to organic protection or conventional protection, little is known about the effect of copper and sulfur fungicides (the only allowed farming) on populations. The sensitivity 158 isolates seven different species (Aureobasidium pullulans, Hanseniaspora guilliermondii, H. uvarum, Metschnikowia sp., Pichia membranifaciens, Saccharomyces cerevisiae Starmerella bacillaris) was evaluated. A. pullulans St....
Blue light (400-430 nm) is known to induce lethal effects in some species of fungi by photo-oxidation caused the excitation porphyrins but mechanisms involved remain poorly understood. In this work, we exposed yeast Saccharomyces cerevisiae a high density flux with two-photon (830 nm equivalent one-photon around 415nm) and used quasi real-time visualization confocal microscopy study initiation dynamics subcellular structures. Our results show that oxidation generated treatments led...
Acacia spirorbis subsp. Labill. is a widespread tree legume endemic to New Caledonia that grows in ultramafic (UF) and volcano-sedimentary (VS) soils. The aim of this study was assess the symbiotic promiscuity A. with nodulating nitrogen-fixing rhizobia harsh edaphic conditions. Forty bacterial strains were isolated from root nodules characterized through (i) multilocus sequence analyses, (ii) efficiency (iii) tolerance metals. Notably, 32.5% belonged Paraburkholderia genus only found UF...
