Jasmonates (JAs) are a class of plant hormones, essential in plant development and defense. JA induces the interaction of the JA receptor Coronatine Insensitive 1 with jasmonate ZIM-domain (JAZ) proteins, and promotes subsequent JAZs degradation, leading to the release of downstream factors and activation of diverse plant development and defense processes. We recently revealed that the IIIe bHLH transcription factors MYC2, MYC3, MYC4 and MYC5 interact with the MYB transcription factors MYB21 and MYB24 to form the bHLH-MYB complex, and JAZs repress the bHLH-MYB complex to regulate JA-mediated stamen development. Here, we further discuss the different properties of the components of the bHLH-MYB complex in expression pattern and stamen regulation.
茉莉酸（JAs）是一类植物激素，对植物发育和防御至关重要。茉莉酸诱导茉莉酸受体冠菌素不敏感蛋白1（Coronatine Insensitive 1）与茉莉酸ZIM结构域（JAZ）蛋白相互作用，并促进随后JAZ蛋白的降解，导致下游因子的释放以及多种植物发育和防御过程的激活。我们最近发现，IIIe类bHLH转录因子MYC2、MYC3、MYC4和MYC5与MYB转录因子MYB21和MYB24相互作用形成bHLH-MYB复合物，并且JAZ蛋白抑制bHLH-MYB复合物以调控茉莉酸介导的雄蕊发育。在此，我们进一步讨论bHLH-MYB复合物各组分在表达模式和雄蕊调控方面的不同特性。
