IP3, DAG, and Ca are second messengers in the phosphoinositol pathway. The pathway begins with the binding of extracellular primary messengers such as epinephrine, acetylcholine, and hormones AGT, GnRH, GHRH, oxytocin, and TRH, to their respective receptors. Epinephrine binds to the α1 GTPase Protein Coupled Receptor (GPCR) and acetylcholine binds to M1 and M2 GPCR. WebOur study confirmed the existence of a correlation between phosphoinositol signaling pathway modification, increased tolerance to stress caused by continuous light exposure, activation of ROS-scavenging enzymes, and up-regulation of molecular activators of non-enzymatic antioxidants in InsP 5-ptase expressing tomato lines.
