摘要:
以盐生植物互花米草(Spartina alterniflora)为试验材料,利用RACE技术克隆到编码Na+/H+逆向转运蛋白的NHX1基因的cDNA全长序列。利用生物信息学软件及网站对获得的基因核苷酸序列及编码的蛋白质序列进行分析,结果发现该核苷酸序列长度为2 277 bp,开放阅读框为1 623 bp,编码540个氨基酸残基,且该基因所编码的蛋白质与植物的Na+/H+逆向转运蛋白NHX1 同源,所以命名为SaNHX1基因。同时氨基酸序列比对显示,其与芦苇(Phragmites australis NHX,BAD95562.1)、玉米(Zea mays NHX,XP_008653443.1)、水稻(Oryza sativa NHX,BAA83337.1)等的NHX亲缘关系相近,同源相似性依次为94%、92%、91%。利用Qiagene Rotor Gene Q荧光实时定量PCR仪对不同时间盐处理及ABA处理的互花米草材料进行荧光定量PCR检测。结果发现,在盐处理及ABA处理的不同处理时期,该基因的相对表达量都发生了明显的变化,这表明该基因受到了盐胁迫及ABA胁迫的诱导,由此可以看出SaNHX1基因与植物的耐盐性有着密切的关系。
