Abscisic acid (ABA) is a major phytohormone mediating important stress-related processes. We recently unveiled an ABA-activated MAPK signaling module constituted of MAP3K17/18-MKK3-MPK1/2/7/14. Unlike classical rapid MAPK activation, we showed that the activation of the new MAPK module is delayed and relies on the MAP3K protein synthesis. In this addendum, we discuss the role of this original and unexpected activation mechanism of MAPK cascades which suggests that MAPKs can regulate both early and long-term plant stress responses.
脱落酸(ABA)是一种介导重要的胁迫相关过程的主要植物激素。我们最近揭示了一个由MAP3K17/18-MKK3-MPK1/2/7/14组成的ABA激活的MAPK信号模块。与经典的快速MAPK激活不同,我们表明新的MAPK模块的激活是延迟的,并且依赖于MAP3K蛋白质的合成。在本附录中,我们讨论了MAPK级联这种原始且意想不到的激活机制的作用,这表明MAPK可以调节植物早期和长期的胁迫反应。
