Abstract
Using a black soybean(BS)cultivar and a yellow soybean(YS)cultivar as the materials,changes in physiological characteristics and function of plasma membrane(PM)H+-ATPase were analyzed in the two soybean cultivars treated with polyethylene glycol(PEG)simulation drought stress under hydroponic conditions.The results indicated that under the treatment conditions of 2%,5% and 10% PEG,with an increase in PEG concentration and treatment time,an elevation in the water loss rate,a decrease in leaf transpiration rate and stomatal conductance were observed in the two soybeans.Under all the same treatment conditions,the water loss rate in YS was lower than that of BS,whereas,the reduction in YS leaf transpiration rate and stomatal conductance was larger than those of BS,indicating that the tolerant ability of YS to drought stress was stronger than that of BS.Under the same treatment conditions,the leaf soluble protein and soluble sugar content in YS was higher than those in BS while the leaf free proline content in BS was higher than that in YS.In the antioxidant enzyme system,the decrease speed in CAT activity in YS leaves was significantly faster than that in BS,leading to a higher H2O2 content in YS leaves than that in BS leaves.As a result,under drought stress conditions,the inhibition in the PM H+-ATPase phosphorylation level and its interaction with 14-3-3 protein in YS leaves was stronger than those in BS leaves.The PM H+-ATPase and proton pump activity in YS leaves were lower than those in BS leaves.Consequently,the stomata aperture in YS leaves was less than that in BS leaves.Leaf transpiration rate and stomatal conductivity in YS were lower than those in BS leaves.This might be an important mechanism underlying the stronger drought tolerance in YS.Soybean is mainly enhance its drought resistance by the means of increasing permeability material soluble protein,soluble sugar and regulating the activity of antioxidant enzyme system.
