As an important metabolic pathway, phosphatidylinositol metabolism generates both constitutive and signalling molecules that are crucial for plant growth and development. Recent studies using genetic and molecular approaches reveal the important roles of phospholipid molecules and signalling in multiple processes of higher plants, including root growth, pollen and vascular development, hormone effects and cell responses to environmental stimuli plants. The present review summarizes the current progress in our understanding of the functional mechanism of phospholipid signalling, with an emphasis on the regulation of Ins(1,4,5)P3-Ca2+ oscillation, the second messenger molecule phosphatidic acid and the cytoskeleton.
作为一条重要的代谢途径，磷脂酰肌醇代谢产生对于植物生长和发育至关重要的组成分子和信号分子。最近利用遗传学和分子生物学方法开展的研究揭示了磷脂分子及其信号传导在高等植物多个过程中的重要作用，包括根系生长、花粉和维管发育、激素效应以及植物细胞对环境刺激的响应。本综述总结了我们目前在理解磷脂信号传导功能机制方面取得的进展，重点关注肌醇-1,4,5-三磷酸（Ins(1,4,5)P3）-钙离子（Ca2+）振荡、第二信使分子磷脂酸以及细胞骨架的调控。
