The Arabidopsis gene COI1 is required for jasmonic acid (JA)-induced growth inhibition, resistance to insect herbivory, and resistance to pathogens. In addition, COH is also required for transcription of several genes induced by wounding or by JA. Here, we use microarray gene transcription profiling of wild type and coil mutant plants to examine the extent of the requirement of COI1 for JA-induced and wound-induced gene transcription. We show that COI1 is required for expression of approximately 84% of 212 genes induced by JA, and for expression of approximately 44% of 153 genes induced by wounding. Surprisingly, COI1 was also required for repression of 53% of 104 genes whose expression was suppressed by JA, and for repression of approximately 46% of 83 genes whose expression was suppressed by wounding. These results indicate that COI1 plays a pivotal role in wound- and JA signalling.
