Abstract
Serine/threonine protein phosphatases are ubiquitous enzymes in all eukaryotes but many of their physiological roles in plants remain unknown. The available results have demonstrated critical functions for these enzymes in the regulation of adaptive stress responses, and recent studies have directed attention to the functional roles of Ser/Thr phosphatases type 2A (PP2A) as components of stress signaling pathways. This review is focused primarily on plant PP2As and their participation in the control of biotic and abiotic stress responses.
摘要
丝氨酸/苏氨酸蛋白磷酸酶是所有真核生物中普遍存在的酶，但它们在植物中的许多生理作用仍然未知。现有结果表明，这些酶在调节适应性应激反应中具有关键功能，最近的研究还将注意力集中在丝氨酸/苏氨酸磷酸酶 2A（PP2A）作为应激信号通路组成部分的功能作用上。本文主要综述了植物 PP2A 及其参与调控生物和非生物胁迫反应的功能。
