质膜H+-ATPase在植物对环境胁迫（如盐碱胁迫）的应答中起着重要作用。我们报道了N-乙基马来酰亚胺敏感因子附着蛋白受体（SNARE）蛋白囊泡相关膜蛋白711（VAMP 711）通过直接调节质膜H+-ATP酶活性参与干旱胁迫。在这项研究中，我们报告，VAMP 7 C（VAMP 711 -14）抑制PM H+-ATP酶活性在高pH值的压力。拟南芥PM H+-ATP酶AHA 2与VAMP 7 C相互作用。VAMP 711的longin结构域与AHA 2相互作用以抑制质膜上的PM H+-ATP酶活性。vamp 711和vamp 711 vamp 712 vamp 713三重突变体的碱性表型表明，VAMP 7 C在调节PM H+-ATP酶活性响应高pH胁迫中是功能冗余的。
ABSTRACT The plasma membrane (PM) H+-ATPase plays an important role in response to environmental stress, such as salt-alkaline stress. We have reported that the N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) protein Vesicle-associated membrane protein 711 (VAMP711) is involved in drought stress by regulating PM H+-ATPase activity directly. In this study, we report that VAMP7C (VAMP711-14) represses PM H+-ATPase activity in response to high-pH stress. The Arabidopsis PM H+-ATPase AHA2 interacts with VAMP7C. The longin domain of VAMP711 interacts with AHA2 to inhibit PM H+-ATPase activity on the plasma membrane. The alkaline phenotype of vamp711 and vamp711 vamp712 vamp713 triple mutants suggested that VAMP7C was functionally redundant in regulating PM H+-ATPase activity in response to high-pH stress.
