摘要
本工作从抗逆性极强的啤酒糖酵母菌株 A S21416 中分离纯化总 R N A 和 m R N A ,以 A M V 逆转录酶合成了单链c D N A 。采用保守引物扩增并克隆了该酵母菌的6 - 磷酸海藻糖合成酶编码基因tps1 ,建立了该基因 D N A 片段的物理图谱,发现其酶切位点与已见报道的6 - 磷酸海藻糖合成酶编码基因相同。
Total RNA and mRNA were isolated and purified from yeast. The first strand of cDNA using oligo(dT) as primer was synthesized and a 1 5 kb DNA fragment was obtained with PCR technique. The restriction map of the DNA fragment was analysed. The results showed that the entire cDNA encoding trehalose 6 phosphate synthase had been cloned.\;
