Abstract
The effect of acid rain(AR) on plasma membrane H+-ATPase activity of rice leaves was investigated under hydroponic conditions in order to explore the relationship between change of H+-ATPase activity and adaptation of plants to AR stress.The results show that AR(pH 2.5) led to a decrease in plasma membrane H+-ATPase activity,intracellular pH and POD activity,while AR(pH 3.0) led to an increase in plasma membrane H+-ATPase activity and POD activity and a decrease in intracellular pH Both groups led to an increase in membrane permeability and MDA content,and reduced Fv/Fm and fresh weight of leaves.AR(3.0pH≤5.5) caused an increase in the plasma membrane H+-ATPase activity and POD activity,and a decrease in intracellular pH.However,no obvious change was observed for membrane permeability and MDA content,indicating that low intensity of AR did not obviously damage cell membrane.Inhibition of low intensity AR on growth was less than that caused by high intensity AR.Under AR stress,H+-ATPase in plasma membrane can regulate intracellular pH within a certain range,and alleviate the damage caused by excess H+ on plasma membrane,thereby showing that crop stress resistance and adaptability to AR were enhanced.
