Phosphatidic acid (PA) has alone afresh been articular as an important signaling atom in both plants and animals. Nonetheless, it already promises to battling the accent of the archetypal additional messengers Ca2+ and cAMP. In plants, its accumulation is triggered in acknowledgment to assorted amoebic and abiotic accent factors, including antibiotic infection, drought, salinity, acerbic and cold. In general, PA arresting assembly is fast (minutes) and transient. Recently, our compassionate of the role of PA accumulation in accent responses as a aftereffect of phospholipases C and D action has abundantly increased. Moreover, the aboriginal protein targets of PA accept been identified. Based on this contempo work, abeyant mechanisms by which PA provokes after furnishings are emerging.
Evidence is accumulating that Phosphatidic acid is a additional messenger. Its akin increases aural account of a advanced array of accent treatments including ethylene, wounding, antibiotic elicitors, osmotic and oxidative stress, and abscisic acid. Added arresting levels are rapidly attenuated by phosphorylating Phosphatidic acid to diacylglycerol pyrophosphate. Phosphatidic acid is the artefact of two signalling pathways, those of phospholipases C and D, the above in aggregate with diacylglycerol kinase. Families of these genes are now getting cloned from plants. Several after targets of Phosphatidic acid accept been identified, including protein kinases and ion channels.
