The phytohormone auxin plays a central role in shaping plant growth and development. With decades of genetic and biochemical studies, numerous core molecular components and their networks, underlying auxin biosynthesis, transport, and signaling, have been identified. Notably, protein phosphorylation, catalyzed by kinases and oppositely hydrolyzed by phosphatases, has been emerging to be a crucial type of post-translational modification, regulating physiological and developmental auxin output at all levels. In this review, we comprehensively discuss earlier and recent advances in our understanding of genetics, biochemistry, and cell biology of the kinases and phosphatases participating in auxin action. We provide insights into the mechanisms by which reversible protein phosphorylation defines developmental auxin responses, discuss current challenges, and provide our perspectives on future directions involving the integration of the control of protein phosphorylation into the molecular auxin network.

生长素的照片:生长素生物合成,运输和信号转导中的可逆蛋白磷酸化

植物激素生长素在决定植物生长发育中起着核心作用。经过数十年的遗传和生物化学研究,已经确定了许多核心分子成分及其网络,基本的生长素生物合成,转运和信号传导。值得注意的是,被激酶催化而被磷酸酶相反地水解的蛋白质磷酸化已经成为翻译后修饰的关键类型,其在所有水平上调节生理和发育生长素的输出。在这篇综述中,我们全面讨论了关于生长素作用的激酶和磷酸酶的遗传学,生物化学和细胞生物学的理解的较早和最近的进展。我们提供有关可逆蛋白磷酸化定义发育性生长素反应的机制的见解,
