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.

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:Plant growth promoting rhizobacteria (PGPR) of the genus Bacillus are successfully used as biofertilizers and biopesticides. They potentially can reduce the use of chemicals in agriculture as an ecologically safe alternative, but to optimize the application of PGPR, more profound knowledge on specific gene regulation and molecular mechanisms of interaction with plants is needed. Advance in sequencing technologies made it affordable to compare transcriptom profiles of relative organisms to check to which extend PGPR strains or closely related species differ in their strategies of plant colonization. This work aimed at analysis of gene regulation in a biotechnological strain Bacillus atrophaeus UCMB-5137 to compare it with the gene expression profile of a generally recognized PGPR strain B. amyloliquefaciens FZB42. It was found out that despite the close taxonomic relatedness, these two organisms developed ability to colonize plants independently and use different strategies of plant colonization. Root exudate has triggered in UCMB-5137 alteration in expression in many genes controlled by stress response transcription factors (TF) SigB and SigD, while SigF, SigH, SigW, CcpA and several other TFs regulated genes associated with quorum sensing and biofilm formation, and adjusted the carbohydrate metabolism. Counting to peculiarities of gene regulation in different PGPR strains will allow optimization of their practical application.

Project description:Plant growth-promoting rhizobacteria (PGPR) are soil microbes that can promote plant growth and/or increase plant resistance to one or multiple stress conditions. These natural resources are environmentally friendly tools for reducing the use of chemical fertilizers and pesticides and for improving the nutritional quality of plants, including pharmacological metabolites. Coriander (Coriandrum sativumL.), commonly known as cilantro or Chinese parsley, is a worldwide culinary and medicinal plant with both nutritional and medicinal properties. Little is known about how PGPR may promote plant growth or affect metabolite profiles in coriander. Here, by usingAeromonassp. H1 that is a PGPR strain, we investigate how coriander yield and quality could be affected by PGPR with transcriptome insights.

Project description:Bacillus velezensis UTB96 was isolated from soil based on its antifungal activity. Whole-genome sequencing of strain UTB96 provided further information about its secondary metabolite gene clusters. Compared to the well-known strain FZB42, UTB96 lacks an IS3 element and a type I restriction endonuclease.

Project description:pc_arcole - arcole / pgpr - What are the genes implicated in the efficiency of nitrogenous nutrition when A.thaliana is inoculated with a PGPR (Plant Growth Promoting Rhizobacteria)? - A.thaliana seeds germinated and grew during ten days until they were transfered in 6 different media: 0,5 mM nitrate with PGPR (Plant Growth Promoting Rhizobacteria), 0,5mM nitrate without PGPR, 2mM nitrate with PGPR, 2mM nitrate without PGPR, 20 mM nitrate with PGPR, 20 mM nitrate without PGPR. Young plantlets grew 7 days in these new mediums. Shoots are collected in eppendorf.

Project description:The present study aims to evaluate the response of the three Mediterranean local grapevines ‘Garnacha Blanca’, ‘Garnacha Tinta’, and ‘Macabeo’ to treatments with biocontrol products (BPs), a botanical extract (Akivi, Dittrichia viscosa extract) and a beneficial microorganism (Bacillus UdG, Bacillus velezensis). A combination of transcriptomics and metabolomics approaches were chosen in order to study grapevine gene expression and to identify gene marker candidates, as well as, to determine grapevine metabolites differentially concentrated in response to BPs treatments. Grapevine plants were cultivated in greenhouse controlled conditions and submitted to the treatments, and thereafter, leaves were sampled 24h after treatment to conduct gene expression study by RNA-sequencing for ‘Garnacha Blanca’ leaves extract and by RT-qPCR for the three cultivars. Differentially expressed genes (DEGs) were investigated for both treatments and highly influenced DEGs were selected to be tested in the three cultivars as treatment gene markers. In addition, extraction of leaf components was performed to quantify metabolites such as phytohormones, organic acids, and phenols. Considering all the upregulated and downregulated genes and enhanced metabolites concentrations, the treatments had an effect on jasmonic acid, ethylene, and phenylpropanoids defense pathways. In addition, several DEG markers were identified presenting a stable overexpression after the treatments in the three grapevine cultivars. These gene markers could be used to monitor the activity of the products in field treatments in future research. Further research will be necessary to confirm these first results under field conditions.
