拟南芥COI1基因是茉莉酸（JA）诱导的生长抑制、抗昆虫植食性和抗病原体所必需的。此外，COH也是创伤或JA诱导的几个基因转录所必需的。在这里，我们使用微阵列基因转录谱的野生型和线圈突变体植物，以检查的程度，要求的COI1的JA诱导和伤口诱导的基因转录。我们表明，COI1是所需的约84%的212个基因的表达诱导JA，约44%的153个基因的表达诱导创伤。令人惊讶的是，COI1也需要抑制53%的104个基因的表达被JA抑制，并抑制约46%的83个基因的表达被抑制的创伤。这些结果表明，COI1在伤口和JA信号传导中起着关键作用。
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.
