摘要根据衣藻、矮牵牛花、Pisumsativum等真核生物hsp70a氨基酸高度保守序列设计两对简并引物，以热休克盐藻cDNA为模板进行巢式PCR扩增，产物经T-A克隆转化至JM109大肠杆菌中，经筛选后测序，将测序结果推导成氨基酸序列进行同源性分析，获得了盐藻热休克蛋白70a cDNA片段。在盐藻中所获得的cDNA片段，核苷酸长度为372 bp，编码126个氨基酸。推导的氨基酸序列与与下列物种的...
摘要 采用cDNA代表性差异分析 (RDA)技术 ,对盐藻在盐胁迫时差异表达的基因进行了分离鉴定 .在分离到的 10个基因中 ,有 5个与已知基因同源 (包括叶绿素a b结合蛋白基因、蛋白磷酸酶I催化亚基基因和 3个核糖体蛋白基因 ) ,还有 5个未知功能基因则是首次在盐藻中被分离 .值得注意的是 ,所有这 5个已知基因的功能都与细胞分裂或盐胁迫有关 .结果表明 :取样时盐藻细胞仍处于恢复阶段 ,...
