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 of two beneficial, and neutral soil bacteria during their interactions in vitro.

Project description:Bacillus amyloliquefaciens FZB42 is a representative organism for Gram positive soil bacteria associated with plant roots and beneficial to plant growth. It is of immense importance to understand mechanisms of this class of bacteria adapting to rhizosphere. In this work employing differential RNA sequencing (RNA-seq) and Northern blot, we systematically identified transcription start sites of mRNAs as well as non-coding regulatory RNAs in FZB42. The genes regulated at different growth phases and located in polycistronic operons were also identified. A set of genes were re-annotated. In addition, a sRNA named Bas01 was identified to be involved in Bacillus sporulation and biofilm formation. The result we obtained provides valuable data for investigation of Bacillus gene expression and molecular details of rhizobacterial interaction with host plants.

Project description:Some soil bacteria promote plant growth, including Pseudomonas species. With this approach we detected significant changes in Arabidopsis genes related to primary metabolism that were induced by the bacteria.

Project description:Plant growth-promoting rhizobacteria (PGPR) are soil beneficial microorganisms that colonize plant roots for nutritional purposes and accordingly benefit plants by increasing plant growth or reducing disease. But it still remains unclear which mechanisms or pathways are involved in the interactions between PGPR and plants. To understand the complex plant-PGPR interactions, the changes in the transcriptome of typical PGPR standard Bacillus subtilis in responding to rice seedlings were analyzed. We compared and anylyzed the transcriptome changes of the bacteria Bacillus subtilis OKB105 in response to rice seedings for 2 h. Total RNA was extracted and Random priming cDNA synthesis, cDNA fragmentation and terminal labeling with biotinylated GeneChip DNA labeling reagent, and hybridization to the Affymetrix GeneChip Bacillus subtilis Genome Array.

Project description:Understanding the mechanisms underlying the establishment of invasive plants is critical in community ecology. According to a widely accepted theory, plant-soil-microbe interactions mediate the effects of invasive plants on native species, thereby affecting invasion success. However, the roles and molecular mechanisms associated with such microbes remain elusive. Using high throughput sequencing and a functional gene microarray, we found that soil taxonomic and functional microbial communities in plots dominated by Ageratina adenophora developed to benefit the invasive plant. There were increases in nitrogen-fixing bacteria and labile carbon degraders, as well as soil-borne pathogens in bulk soil, which potentially suppressed native plant growth. Meanwhile, there was an increase of microbial antagonism in the A. adenophora rhizosphere, which could inhibit pathogenicity against plant invader. These results suggest that the invasive plant A. adenophora establishes a self-reinforcing soil environment by changing the soil microbial community. It could be defined as a ‘bodyguard/mercenary army’ strategy for invasive plants, which has important insights for the mitigation of plant invasion.

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 of two beneficial, and neutral soil bacteria during their interactions in vitro. We performed nine hybridizations (macroarray) with samples derived from Laccaria bicolor cultivated alone (3 biological replicates), with P. fluorescens BBc6R8 (3 biological replicates) and with Pf29Arp (3 biological replicates)

Project description:During plant life, roots support beneficial associations with soil inhabiting microbes, mainly fungi and bacteria. Increasing evidence suggests that plant-associated microorganisms can promote plant growth and expand immune functions of the plant host. The beneficial entomopathogenic fungus Beauveria bassiana colonizes plant tissues in an asymptomatic way, triggering poorly characterized plant metabolic changes, which negatively affect both pest insects and plant pathogens. B. bassiana has an extremely broad host spectrum, including tomato (Solanum lycopersicum L.). In order to obtain a great overall snapshot of molecular events regulating tomato-B. bassiana interaction, plant proteome and hormonome changes induced over the time by the fungus have been in-depth analyzed by using a combination of high throughput profiling techniques and bioinformatics tools. The proteomics data highlighted interesting molecular pathways affected by B. bassiana related to primary and secondary metabolism and plant growth. Additionally, downregulation of a member of the endochitinase family and upregulation of calcium channel and transporter proteins suggested well-established plant-fungus symbiosis. The molecular pathways linked to protein/amino acids turn-over and to the biosynthesis of energy compounds shed some light on the strategies exploited by the plant to get the most out of the beneficial interaction in improving growth and development.
