摘要: Evidence is accumulating that phosphatidic acid a second messenger. Its level increases within minutes of wide variety stress treatments including ethylene, wounding, pathogen elicitors, osmotic and oxidative stress, abscisic acid. Enhanced signal levels are rapidly attenuated by phosphorylating to diacylglycerol pyrophosphate. Phosphatidic the product two signalling pathways, those phospholipases C D, former in combination with kinase. Families these genes now being cloned from plants. Several downstream targets have been identified, protein kinases ion channels.
