Low and High Temperatures Enhance Guanylyl Cyclase Activity in Arabidopsis Seedlings

Guanylyl cyclase system plays a crucial role in intracellular signaling in animals and plants involving cyclic guanosine 3’,5’-monophosphate (cGMP) as a signaling intermediate. cGMP is a well-established intracellular molecule that takes part in diverse physiological processes, biotic and abiotic stress responses in higher plants. We have focused here on participation of cGMP as a secondary messenger in temperature stress-induced pathways and the mechanism of cGMP-mediated signal transduction in Arabidopsis seedlings.
