The phytohormone abscisic acid (ABA) is a vital endogenous messenger that regulates diverse physiological processes in plants. The regulation of ABA signaling has been well studied at both the transcriptional and translational levels. Post-translational modification of key regulators in ABA signaling by the 26S ubiquitin proteasome pathway is well known. Recently, increasing evidence demonstrates that atypical turnover of key regulators by the endocytic trafficking pathway and autophagy also play vital roles in ABA perception, signaling, and action. We summarize and synthesize here recent findings in the field of ABA signaling.

ABA信号传导中的非26S蛋白酶体内膜运输途径。

植物激素脱落酸（ABA）是重要的内源信使，它调节植物的各种生理过程。ABA信号的调节已在转录和翻译水平上进行了很好的研究。通过26S泛素蛋白酶体途径对ABA信号转导中的关键调节子进行翻译后修饰是众所周知的。最近，越来越多的证据表明，内吞运输途径和自噬的关键调控因子的非典型转换在ABA的感知，信号传导和作用中也起着至关重要的作用。我们在这里总结和综合ABA信号传导领域的最新发现。
