| 摘 要： | 20世纪 80年代早期人们意识到构成细胞膜的磷脂不只是一道将细胞物质与外界隔开的屏障,而且是细胞对外界环境刺激作出应答的物质基础。磷脂酰肌醇（ｐｈｏｓｐｈｏｔｉｄｙｌｉｎｏｓｉｔｏｌ,ＰＩ）不但是构成细胞膜的重要组分（约占细胞膜组分的 10 %）,在细胞内外环境信号的传递方面也起着重要的作用［1］。磷脂酶（ｐｈｏｓｐｈｏｌｉｐａｓｅ）水解磷脂后产生的三磷酸肌醇 （ｉｎｏｓ ｉｔｏｌｔｒｉｓｐｈｏｓｐｈａｔｅ,ＩＰ3 ）／二酰基甘油（ｄｉａｃｙｌｇｌｙｃｅｒｏｌ,ＤＡＧ）、磷脂酸（ｐｈｏｓｐｈａｔｉｄｉｃａｃｉ…

Phospholipases in Signalling Transduction of Higher Plants |
| |
| Abstract: | 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. |
