中文摘要：
髓细胞组织增生蛋白（Myelocytomatosis proteins，MYC）类转录因子，是植物激素茉莉酸（JA）响应途径中的激活转录因子，广泛存在于动植物中，MYC2转录因子属于bHLH类转录因子家族，含有bHLH保守结构域，是当前MYC类转录因子中研究最透彻的一个。随着对植物抗生物逆境不断深入研究，对MYC2的研究亦逐渐清晰。本文综述了转录因子MYC2通过与下游靶基因形成一个层级转录级联，放大转录输出，参与调控植物抗生物逆境，着重阐述了水稻OsMYC2转录因子在抗生物逆境中的作用；茉莉酸ZIM结构域蛋白（Jasmonate ZIM-domain，JAZ）作为JA信号的转录抑制因子，抑制MYC2的活性并参与介导JA信号途径，为MYC2功能机制研究提供了参考，并对今后的研究热点与方向进行了展望。
英文摘要：
The transcription factor myelocytomatosis proteins (MYCs) are activating transcription factors in the response pathway of jasmonic acid (JA) in plants. They are widely found in animals and plants. MYC2 belongs to the family of bHLH and contains the conserved domain of bHLH. It is the most thoroughly studied of the current MYC transcription factors. With the deep study of plant resistance to biotic stress, the research on MYC2, which mediates JA signaling pathway, has gradually become clear. This review summarized the role of transcription factor MYC2 in amplifies transcriptional output, participates in the regulation of plant target genes, cascade with regulating plant resistance to biotic stress by forming a hierarchical transcription downstream antibiotic stress, and highlights the role of rice transcription factor OsMYC2 in antibiotic stress. JAZ is the transcriptional inhibition of JA signaling factor, which participates in mediating JA signaling pathway by inhibiting the activity of MYC2, provides information for the study of MYC2 functional mechanism, and prospects for future research hot spot and directions.
