Transcription profiling of Arabidopsis plants mis-expressing AtMYB30 AFTER Xanthomonas inoculation AT early timepoints

ABSTRACT: Plant immune responses to pathogen attack involve various defense mechanisms and among them, the Hypersensitive Response (HR), a form of programmed cell death occurring at invasion sites. AtMYB30, a transcription factor acts as a positive regulator of a cell death pathway conditioning the HR. We show by microarray analyses of Arabidopsis plants misexpressing AtMYB30 that the genes encoding the four enzymes forming the acyl-coA elongase complex, responsible for very long chain fatty acids (VLCFA) biosynthesis, are putative targets. Experiment Overall Design: 18 samples are analyzed : Leaves of 4 week-old plants syringe-infiltrated with the Xcc147 strain (or not) were harvested. In experiment 1, we selected 4 timepoints : T0 (not inoculated), 90-105 min, 2-4 h and 6 h post inoculation in t
