Includes bibliographical references (leaves 199-253). / This study attempted to characterize at a transcriptional level, the defence responses of Arabidopsis thaliana after infection by Botrytis cinerea, using microarrays. The first microarray experiment focused on profiling Arabidopsis genes induced by B. cinerea over time (temporal) while the second investigated spatial expression of Arabidopsis genes from the point of inoculation. A number of genes were up- and down-regulated specifically at 12 hrs, others at 24 hrs while others were up- and down-regulated at both time points. Similarly, some genes were specifically induced very close to the lesion while others in more distal tissue.
