烟草茉莉素信号途径相关基因
摘 要:茉莉素途径是植物重要的信号途径,对植物的生长发育过程和抗逆过程起重要的调控作用。有生物活性的茉莉酸衍生物JA-Ile(jasmonoyl-isoleucine)与茉莉素受体复合体SCFCOI1结合后,导致茉莉素途径负调控因子JAZ蛋白由26S蛋白酶体(即蛋白泛素化降解途径)降解,并释放出茉莉素途径转录激活因子MYC2,从而激活茉莉素信号途径下游与植物生长发育相关和抗逆相关的功能基因表达和生理变化。对该信号途径中3个重要基因COI1、JAZ、MYC2在烟草中的研究情况进行了综述。

Abstract: Jasmonate signaling pathway plays an important role in the regulation of plant development and stress response. At the presence of Jasmonate, its biological active derivative JA-Ile (jasmonoyl-isoleucine) is perceived by the receptor complex SCFCOI1, which leads to the degradation negative regulator JAZ protein via 26S proteasome and then releases the transcriptional activator MYC2 to activate the expression of downstream genes and to activate physiological responses. This article will summarize the research progresses on the genes of the key Jasmonate pathway regulators COI1, JAZ and MYC2 in tobacco.
