Calcium-dependent protein kinases (CPKs), the best-characterized calcium sensors in plants, regulate many aspects of plant growth and development as well adaptation to biotic abiotic stresses. However, how CPKs antioxidant defense system remains largely unknown. We previously found that impaired function OsCPK12 leads oxidative stress rice, with more H
