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.

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) 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:In the present investigation, the genetic diversity architecture of 96 deep-water rice genotypes of Assam and association mapping strategy was, for the first time, applied to determine the significant SNPsand genes for deep-water rice. These genotypes are known for their unique elongation ability under deep-water condition.The internode elongation under water related genes will be identified here can provide affluent resources for rice breeding especially in flood-prone areas. We investigated the genome-wide association studies (GWAS) using 50 K rice genic SNPchip across 96 deep-water rice genotypes collected from different flood-prone districts/villages of Assam.

Project description:Sorghum (Sorghum bicolor) is one of the world's most important cereal crops. S. propinquum is a perennial wild relative of S. bicolor with well-developed rhizomes. Functional genomics analysis of S. propinquum, especially with respect to molecular mechanisms related to rhizome growth and development, can contribute to the development of more sustainable grain, forage, and bioenergy cropping systems. In this study, we used a whole rice genome oligonucleotide microarray to obtain tissue-specific gene expression profiles of S. propinquum with special emphasis on rhizome development. A total of 548 tissue-enriched genes were detected, including 31 and 114 unique genes that were predominantly expressed in the rhizome tips (RT) and internodes (RI), respectively. Further GO analysis indicated that the functions of these tissue-enriched genes corresponded to their characteristic biological processes. A few distinct cis-elements, including ABA-responsive RY repeat CATGCA, sugar-repressive TTATCC, and GA-responsive TAACAA, were found to be prevalent in RT-enriched genes, implying an important role in rhizome growth and development. Comprehensive comparative analysis of these rhizome-enriched genes and rhizome-specific genes previously identified in S. propinquum indicated that phytohormones, including ABA, GA, and SA, are key regulators of gene expression during rhizome development. Co-localization of rhizome-enriched genes with rhizome-related QTLs in rice and sorghum generated functional candidates for future cloning of genes associated with rhizome growth and development. In conclusion, a whole rice genome oligonucleotide microarray was used to profile gene expression across five tissues of the perennial wild sorghum S. propinquum. Expression patterns of the five tissues were consistent with the different functions of each organ, and RT- and RI-enriched genes revealed clues regarding molecular mechanisms of rhizome development. Plant hormones, including ABA, GA, and SA, function as key regulators of rhizome gene expression and development. To shed further light on the identities of rhizome-specific genes, rhizome-enriched candidates were identified using QTL co-localization and comparative analysis. In this study, the specific gene expression patterns across five tissues, including rhizome tip (RT, distal 1 cm of the young rhizome), rhizome internodes (RI), shoot tip (ST, distal 5 mm of the tiller after removing all leaves), shoot internodes (SI) and young leaf (YL) in Sorghum propinquum, especially in the rhizome, were characterized by using a rice genome array. Three independent biological replicates for each tissue from individual plants were performed. The reference was equivalent to a mix of the 5 tissues.

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.
