玉米蔗糖磷酸合成酶(SPS)基因的克隆及表达载体的构建
Gene cloning of maize sucrose phosphate synthetase and construction of plant expression vector
【摘要】 利用RT-PCR方法从玉米幼苗叶片总RNA中克隆出玉米的蔗糖磷酸合成酶(SPS)基因的全长cDNA片段。该片段与文献报道的序列具有99%的同源性。并分别构建了以双CaMV35S为启动子,以Tnos为终止子的植物双元表达载体PBISPS和以Pcab为启动子,以T35S为终止子的植物表达载体PBSPS,其中PBISPS含有NPTⅡ选择标记基因,PBSPS不含选择标记基因。
【Abstract】 By means of RT-PCR methods,we have cloned the all cDNA fragment of maize SPS gene from the total RNA in maize seedling leaf.These fragments have 99% expressing vector(PBISPS),respectively,using CaMV35S as primer,Tnos as plant binary expression vector of terminater;using pcab as primer,T35s as plant expression vector of terminater(PBSPS).Among them PBISPS contains NPT selective mark gene,PBSPS don’t have.
