Project description:Transcriptional profiling of Xanthomonas campestris pv. campestris 8004 comparing control wild type strain with ravA (or ravS or ravR) mutant The effects of mutating ravS, ravR and ravA on EPS synthesis, biofilm production and motility were very different , the factors responsible for these differences are not clear. With comparative analysis of the regualtion pathways by RavS, RavR and RavA, we can indentify different genes regulated by these three genes and maybe explain the different phenotypes caused by these genes mutations.

Project description:Xylem sap of young cabbage plantlets was recovered from root pressure exudation and used as a growth medium for the vascular pathogen Xanthomonas campestris pv campestris, the causative agent of the black rot of Brassicaceae.
Project description:Black rot, caused by Xanthomonas campestris pv. campestris (Xcc) is one of the most devastating diseases of cruciferous crops worldwide. The pathogen infects and multiplies in plant vascular tissues and, as the disease progresses, the veins of infected tissues turn black and characteristic V-shaped lesions appear along the margins of leaves.The aim of this work is to identify differentially expressed genes from Brassica oleracea during early infection by Xcc, in an attempt to identify proteins related to resistance. Cabbge seedlings were inoculated with Xanthomonas campestris pv campestris (Xcc) suspension and cabbage gene expression at 6h., 24h. And 48h. After inoculation was assessed with help of Brassica 95k EST microarray chip.
Project description:We performed a transcriptomic analysis of the necrotrophic bacteria Xanthomonas campestris pv. campestris exposed to two different isothiocyanates (allyl-isothiocyanate and indol-3-carbinol), searching for mechanisms of adaptation and detoxification of these chemicals.
Project description:Gene expression profiling of upland cotton line Im216 to inoculation with Xanthomonas campestris pv. malvacearum race 1. Fifth or sixth leaves of the bacterial blight-resistant cotton line Im216, which had been grown in a plant growth chamber, were infiltrated with a suspension of about 5x10^6 colony-forming units ml^-1 of Xanthomonas campestris pv. malvacearum race 1 in sterile saturated CaCO3 solution or were not inoculated (control). Keywords: Time-course
