Activation of plant respiratory burst oxidase homologs (RBOHs) to generate reactive oxygen species (ROS) is a crucial defense signaling event. RBOH activation occurs predominantly through N-terminal phosphorylation and the binding of a small GTPase. Two recent papers reported that C-terminal phosphorylation and ubiquitination modulates AtRBOHD activity, which extends our understanding of the fine-tuning of RBOH signaling in plant immunity.
植物呼吸爆发氧化酶同源物(RBOHs)的激活以产生活性氧物种(ROS)是一个关键的防御信号事件。RBOH 的激活主要通过 N 端磷酸化和小 GTP 结合发生。最近的两篇论文报道 C 端磷酸化和泛素化调节 AtRBOHD 的活性,这扩展了我们对植物免疫中 RBOH 信号精细调控的理解。
