Abstract: V-ATPase is a muti-subunits protein complex, the c subunit is mainly responsible for V-ATPase assembly and proton channel formation. We measured the expression profiles of V-ATPase subunits in exogenous overexpression ThVHAc1 Arabidopsis under salt by using real time RT-PCR. Twenty-eight V-ATPase subunits were all effected by exogenous ThVHAc1, and five Arabidopsis c subunits were down-regulated expression, indicating that ThVHAc1 affected the V-ATPase activity by altered the expression of V-ATPase all subunits. Between the expression of V-ATPase subunit and V-ATPase activity showed non-monolithic relationship, they were functioned together coordinately on V-ATPase to response to slat stress.
