摘要
Phosphotidylinositol (PI) can be hydrolyzed into inositol 1,4,5_ trisphosphate/diacylglycerol (IP 3/DAG), the second signalling messengers which can be further phosphorylated by phospholipases to other signalling molecules, and phosphatidic acid (PA) and lysophosphoglyceride (lysoPI) involved in many signalling cascades. It has been shown that PI signalling pathway and the involved enzymes are critical for plant development and response to environmental factors. Three classes of phospholipases, named PLA 2, PLC and PLD, were classified based on their cleavage sites, and the presence of variants of isoforms indicating their different functions in plant growth/development. The update information of phospholipases with focus on the interaction of plant hormone and environmental factors has been provided.
