Abstract excerpt
Previous studies have demonstrated that methyl jasmonate (MeJA) induces stomatal closure dependent on change of cytosolic free calcium concentration in guard cells. However, these molecular mechanisms of intracellular Ca(2+) signal perception remain unknown. Calcium-dependent protein kinases (CDPKs) function as Ca(2+) signal transducers in various plant physiological processes. It has been reported that four...
