ABA-Dependent Regulation of Calcium-Dependent Protein Kinase Gene in Cultivated and Wild Soybeans.

Calcium-dependent protein kinases (CDPKs) regulate plant development and stress responses. However, the interaction of these protein kinases with the abscisic acid (ABA) stress hormone signalling system has not been studied in detail. In , AtCPK1 plays an important role in the acclimation of plants to environmental stresses.
