利用PeR方法扩增香蕉红素氧还蛋白基因的保守结构域序列CdRD和开放性阅读框序列FRD,并在其上下游分别引入Nde Ⅰ和Sal Ⅰ酶切位点,双酶切后与同样经Nde Ⅰ和Sal Ⅰ双酶切的诱饵质粒载体pGBKT7连接,构建重组诱饵质粒pGBKT7-CdRD和pGBKT7-FRD,并将此两重组诱饵质粒转入酵母菌株AH109中进行营养缺陷型分析检测毒性及自激活.结果表明,成功构建了重组诱饵质粒pGBKT7-CdRD和pGBKT7-FRD,并且其无自激活报告基因作用,对酵母菌株也无毒性作用.这说明此两个重组诱饵质粒可用于酵母双杂交系统,为从香蕉叶片cDNA文库中筛选获得与香蕉红素氧还蛋白基因的保守结构域序列CdRD和开放性阅读框序列FRD相互作用的受体蛋白基因奠定了基础.
利用PeR方法擴增香蕉紅素氧還蛋白基因的保守結構域序列CdRD和開放性閱讀框序列FRD,併在其上下遊分彆引入Nde Ⅰ和Sal Ⅰ酶切位點,雙酶切後與同樣經Nde Ⅰ和Sal Ⅰ雙酶切的誘餌質粒載體pGBKT7連接,構建重組誘餌質粒pGBKT7-CdRD和pGBKT7-FRD,併將此兩重組誘餌質粒轉入酵母菌株AH109中進行營養缺陷型分析檢測毒性及自激活.結果錶明,成功構建瞭重組誘餌質粒pGBKT7-CdRD和pGBKT7-FRD,併且其無自激活報告基因作用,對酵母菌株也無毒性作用.這說明此兩箇重組誘餌質粒可用于酵母雙雜交繫統,為從香蕉葉片cDNA文庫中篩選穫得與香蕉紅素氧還蛋白基因的保守結構域序列CdRD和開放性閱讀框序列FRD相互作用的受體蛋白基因奠定瞭基礎.

The conserved domain and open reading frame of Musa acuminata rubredoxin (MaRD) was amplified by PCR with the Nde Ⅰ and Sal Ⅰ restriction sites incorporated into the primers,digested by restriction enzymes and ligated with the vector pGBKT7 which also digested by the same restriction enzymes to construct recombinant bait plasmid pGBKT7-CdRD and pGBKT7-FRD.After the transform of recombinant plasmid into yeast strain AH109,the autonomous reporter gene activation was then observed with attxotrophic plate assay.The results suggested that the recombinant plasmids pGBKT7-CdRD and pGBKT7-FRD were constructed,which neither had the abihty of self-activation,nor yeast cell toxicity.Therefore,the recombinant plasmid can be used in yeast two-hybrid system to screen a banana cDNA library for proteins interacted with the bait protein pGBKT7-CdRD and pGBKT7-FRD.
