Project description:Root exudates play an important role in plant-microbe interaction. The transcriptional profilings of plant growth-promoting rhizobacteria Bacillus amyloliquefaciens SQR9 in response to maize root exudates under static condition, were investigated by an Illumina RNA-seq for understanding the regulatory roles of the root exudates.

Project description:Purpose: The recent publication of the fungal mutualist R. irregularis genome facilitated transcriptomic studies. We here adress the gene regulation of R. irregularis in response to root exudates from rice wild-type and osnope1 (no perception candidate - mutant unable to host arbuscular mycorrhizal fungi) Methods: Spores of R. irregularis were treated with root exudates and collected at 1 hour, 24 hours and 7 days after addition. To monitor fungal gene regulation, control conditions were also prepared at T0, 1h, 24h and 7d. mRNA were sequenced by HiSeq Illumina. Reads were mapped on the Rhizophagus irregularis genome assembly (Gloin1 - Tisserant et al., PNAS, 2013) using CLCworkbench suite. Results: -At 1h, a set of 92 fungal genes were found up-regulated in response to wt root exudates (92), not to osnope1 root exudates, many of them being involved in cell signaling. -At 24h and 7d, numerous genes putatively involved in primary metabolism were up-regulated in response to wt root exudates, not in response to osnope1 root exudates -Several vital genes involved in cell development are repressed in response to osnope1 RE compared to wt RE. Conclusions: these results argue for a high metabolic activity induced by wt root exudates, not by osnope1 root exudates.

Project description:Root exudates play an important role in plant-microbe interaction. The transcriptional profilings of plant growth-promoting rhizobacteria Bacillus amyloliquefaciens SQR9 in response to maize root exudates under static condition, were investigated by an Illumina RNA-seq for understanding the regulatory roles of the root exudates. 4 treatments, including 2 blank control (24 h and 48 h-post inoculation, named as 5 and 15, respectively), and 2 treatments with maize root exudates (24 h and 48 h-post inoculation, named as 7 and 17, respectively)

Project description:Transcription profiling by array of Bacillus amyloliquefaciens strain FZB42 after interaction exudates (IE) treatment, at OD600=1.0 and at OD600=1.0 respectively. IE was the root exudates prepared from maize plants growing with FZB42. The reference was treated with the root exudates (RE), prepared from maize plants grown in an axenic system.

Project description:In general, the endosphere isolate EC18 showed more numbers of genes significantly altered in the presence of root exudates than the soil isolate SB8 . Some of the altered genes in the two strains showed overlap. Some of these genes were previously reported to be involved in microbe-plant interactions, such as organic substance metabolism, oxidation reduction, transmembrane transportation and a subset with putative or unknown function. It was also found some genes showed opposite trend among the two strains.

Project description:Endophytic colonization is a very complex process which is not yet completely understood. Molecules exuded by the plants may act as signals which influence the ability of the microbe to colonize the host or survive in the rhizosphere. Here we investigated whether root exudates of the host might play a role in initiating the endophyte-rice interaction. The whole genome microarray approach was used to investigate the response of the diazotrophic model endophyte, Azoarcus sp. strain BH72, to exudates of O. sativa cv. Nipponbare in order to identify differentially regulated genes. Azoarcus sp. strain BH72 was grown in the presence or absence of root exudates of Oryza sativa cv. Nipponbare for two different time points, and differences in the gene expression profile were monitored. RNA from cells grown on synthetic medium for 1 and 4 hours respectively in presence (experiment) and absence (control) of exudates was used for two color whole genome microarray approach.
