Regulation of Exogenous Salicylic Acid, Calcium and Nitric Oxide to D1 Protein and Function of Photosystem Ⅱ in Wheat (Triticum Asetinum L.) Leaves Under Heat and High Irradiance Stress
In China's Huanghuai winter wheat zone, cross-stress of heat and high irradiance occurs frequently, which results in damage to photosynthetic apparatus, decline of photosynthesis in leaves, retard of seed growth and decrease in grain yield. In this paper, we studied the regulating effects of exogenous salicylic acid(SA), calcium ion (Ca2+)and nitric oxide (NO) on chloroplast protein kinase(PK), phosphorylation of D1 protein, performance of photosystemⅡ(PSⅡ), resistance to oxidative damage induced by ...
