Project description:Transcriptional profiling of Oryza sativa japonica Nipponbare roots after 14 days post infection with Xanthomonas oryzae pv. oryzae strain PXO99 , the goal is to understand the transcriptomic response of rice roots to colonization by bacterial pathogen
Project description:In previous work in our group, shotgun genome sequencing of Arthrobacter sp. revealed potential new P450 monooxygenases and many other oxidoreductases with putative hydroxylation activity. A targeted approach to identify enzymes involved in the degradation of certain molecules is proteomic analysis. In the case of growth on certain substances, enzymes like P450s, which are responsible for the observed organism’s capabilities, might be overexpressed or initially induced.
Project description:Arthrobacter chlorophenolicus A6 is a 4-chlorophenol degrading soil bacterium with high phyllosphere colonization capacity. Till now the genetic basis for the phyllosphere competency of Arthrobacter or other pollutant-degrading bacteria is uncertain. We investigated global gene expression profile of A. chlorophenolicus grown in the phyllosphere of common bean (Phaseolus vulgaris) compared to growth on agar surfaces.
Project description:Transcription profiling of the DSF regulon in Xanthomonas oryzae pv. oryzae (Xoo) using wild type and the rpfF mutant. Cell-cell signaling mediated by the quorum sensing molecule known as Diffusible Signaling factor (DSF) is required for virulence of Xanthomonas group of plant pathogens. DSF in different Xanthomonas and the closely related plant pathogen Xylella fastidiosa regulates diverse traits in a strain specific manner. The transcriptional profiling performed in this study is to elucidate the traits regulated by DSF from the Indian isolate of Xanthomonas oryzae pv. oryzae, which exhibits traits very different from other Xanthomonas group of plant pathogen. In this study, transcription analysis was done between a wild type Xanthomonas oryzae pv. oryzae strain and an isogenic strain that has a mutation in the DSF biosynthetic gene rpfF.
