How Phospholipase C Regulates Stress Tolerance and Development in Plants?
Lipid signaling pathways regulate many cellular processes in eukaryotes. PLCs are the major players in lipid signaling, triggered by numerous environmental cues in plants.
After hydrolysis, DAG remains attached to the membrane and activates protein kinase C (PKC) while IP3 moves to the cytoplasm to bind ligand gated Ca2+ channels (IP3 receptors) resulting in the release of Ca2+ from the intracellular reservoirs.
This model doesn’t hold completely true and still debatable in plant system, as the level of PI P2 in plant membrane is very low, and no IP3 receptors, and equivalents of animal PKC have not been identified till date in plants.
