THE GENERATION OF Ca2+ SIGNALS IN PLANTS | Annual …
The calcium ion is firmly established as a ubiquitous intracellular second messenger in plants. At their simplest, Ca-based signaling systems are composed of a receptor, a system for generating the increase in [Ca], downstream components that are capable of reacting to the increase in [Ca], and other cellular systems responsible for returning [Ca] to its prestimulus level. Here we review the
