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.
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.

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
