Project description:In order to get insights into the ability of ectomycorrhizal fungi to perceive their biotic environment as well as into the mechanisms of the interactions between ectomycorrhizal fungi and soil bacteria, we analysed the transcriptomic response of the ectomycorrhizal fungus L. bicolor and the strain Pseudomonas fluorescens Pf29Arp during their interactions in vitro.
Project description:In order to get insights into the ability of ectomycorrhizal fungi to perceive their biotic environment as well as into the mechanisms of the interactions between ectomycorrhizal fungi and soil bacteria, we analysed the transcriptomic response of the ectomycorrhizal fungus L. bicolor and the strain Pseudomonas fluorescens Pf29Arp during their interactions in vitro. We performed six hybridizations (shotgun DNA microarray) with samples derived from Pseudomonas fluorescens Pf29Arp cultivated alone or with Laccaria bicolor S238N in vitro (3 control biological replicates and 3 biological replicates with L. bicolor)

Project description:This SuperSeries is composed of the following subset Series: GSE33907: Tannic acid (20 µg/ mL) treatment effect on transcriptome of Pseudomonas fluorescens Pf-5 GSE33908: Tannic acid (160 µg/ mL) treatment effect on transcriptome of Pseudomonas fluorescens Pf-5 Refer to individual Series
Project description:ra13-03_pyo - effect of pseudomonas fluorescens pyoverdine on a.thaliana defence responses and iron homeostasis - Analyse de l’effet d’un traitement par la pyoverdine sur les gènes liés à l’homéostasie du fer et à l’induction des réactions de défense. - Arabidopsis thaliana plants cultivated in hydroponic conditions were treated for 3 days by pyoverdin, a bacteriosiderophore from Pseudomonas fluorescens C7R12 in a medium supplemented or deprived of iron.
Project description:The goal of this study was to evaluate the molecular mechanisms by which Brachypodium distachyon grown with and without Pseudomonas fluorescens (P. fluorescens) strain SBW25 respond to Fe deprivation. Fe deprivation induced Brachypodium secretion of phytosiderophores and reduced biomass production while inoculation with P. fluorescens resulted in alterations of extracellular metabolite abundances. Results provide insight into the role of iron in interactions between a host plant and root associated bacteria.
