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: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: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.

Comparative analysis of the regualtion pathways by RavS, RavR and RavA Two-condition experiment, wild type vs. mutants. Biological replicates were independently grown and harvested. One replicate per array
Project description:To investigate the effect of the transcriptional regulator Crt1 on the transcirptome of Xanthomonas campestris pv. camp (Xcc), comparative genome-wide transcriptome analysis was conducted. For this purpose, the wild-type strain Xcc B100 and the mutant strain Xcc Δcrt1 were each cultivated in triplicates in minimal medium supplemented with glucose as sole carbon source. RNA samples from the biological replicates were obtained at an early stationary growth stage. RNA was isolated and the three replicates were combined for each strain. Furthermore, the data from two arrays (dye swap) were combined to provide statistically reliable conclusions.
