摘要:
为研究油菜ASL基因(BnALS)启动子的功能,根据油菜基因组信息,提取得到BnASL基因上游区域的碱基序列,通过设计特异性引物对,利用PCR扩增克隆得到大小为1 048个碱基的片段。序列分析结果显示,该序列富含TATA box和CAAT box等启动子核心调控序列,并有多个与逆境、激素、光响应等表达相关的顺式作用元件,如MBS元件、ABRE元件、HSE元件 CGTCA-motif、TGA-motif等。为了进一步研究其启动子功能,将其与β-葡萄糖苷酸酶(GUS)基因融合,构建了植物表达载体p1304-P,通过根癌农杆菌介导法转化烟草(Nicotiana benthamiana),对PCR阳性的再生烟草苗进行GUS组化分析,检测GUS基因在转基因烟草中的瞬时表达情况。结果表明,克隆的BnASL基因上游序列能够驱动GUS基因在烟草根、茎、叶等组织中的表达,推测油菜ALS基因上游的1 048 bp片段具有组成型表达的启动子功能。
