拟南芥钙依赖蛋白激酶研究进展

Plant could sense and respond to internal and environmental stimuli through a complicated cell signaling network, and which enables them to survive the ever changing environment, as well as to accomplish their normal life cycle. The concentration alteration of cytosolic free calcium is a well known secondary messenger, and which could be triggered by perception of s followed by activation of downstream signal cascade via a serial of calcium sensors. CDPKs (calcium-dependent protein kinase) are well known calcium sensors in plant signaling, and this review focuses on their common structural characteristics, expression profile and especially on recent advances of their physiological functions in Arabidopsis.
