Cluxtalx analysis indicated that the v - h + - atpase b , h and c subunits from halophyte s . salsa had high amino acid sequence identity with subunits from mesembryanthemum crystallinum , which is an inducible cam species as its growth rate is maximal at moderate salt concentrations . sequence alignment results suggested that the evolutions of v - h + - atpase subunits b , h and c were involved in environmental adaptation and these subunits of v - h + - atpase might have an important role in responses of plants to salt stress Clustalx分析表明盐地碱蓬液泡膜h ~ + - atpaseb 、 h 、 c亚基氨基酸序列与来源于兼性cam植物冰叶日中花液泡膜h ~ + - atpase的相应亚基具有最高的序列一致性,表明植物液泡膜h ~ + - atpaseb 、 h 、 c亚基的进化可能与环境刺激有关并且可能参与了植物对盐胁迫的响应。
