Abstract:
Effect of FC on aluminum tolerance of Alsensitive black soybean(SB)roots under Al stress were investigated in this research.The results showed that adding 1 μmol.L-1FC for 8 h,it could significantly release the inhibition of 50 μmol.L-1Al stress on the root growth of SB,and increase its relative root growth(RRG)by 36.4%.CoImmunoprecipitation(Co-IP)analysis showed that adding 1 μmol.L-1FC could enhance the interaction between 14-3-3 proteins and phosphorylated PM H+-ATPase,which increased PM H+-ATPase activity to approximately 1 fold,significantly increasing proton efflux and citrate secretion to approximately 2fold in SB roots under 50 μmol.L-1 Al stress.These results confirmed FC was used for enhancing interaction of the 14-3-3 protein and PM H+-ATPase and the activity of PM H+-ATPase,thereby increasing citrate secretion and Altolerance in SB roots under Al stress.
