Abstract:

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.

Key words: transcription factor MYC2, jasmonic acid (JA), biologic stress, transcription factor JAZ, research progress
