摘要:
以甘蓝型油菜冬性品种中双11的基因组为模板,克隆了BnaC05g31880D基因起始密码子上游-1 525 bp的启动子序列。顺式调控元件的预测分析表明,该启动子含有真核生物启动子必需的核心调控元件TATA box和CAAT box,同时还存在较多的其他功能元件,如光信号响应调控元件ATCT-motif、Box 4、ACE、I-box、LAMP-element、TCT-motif,厌氧感应必需的顺式作用元件ARE,茉莉酸甲酯响应顺式作用元件CGTCA-motif和TGACG-motif,玉米醇溶蛋白代谢调控元件O2-site,赤霉素响应元件P-box等。为了验证该启动子的表达模式,构建了由其驱动GUS报告基因的植物融合表达载体DX2181G-pBnaC05g31880D,并采用农杆菌介导的花序浸染法转化野生型拟南芥(Col-0)。对筛选和鉴定的阳性转基因株系进行GUS组织化学法染色,结果表明,GUS活性在拟南芥的各个组织中均有较强表达水平,这表明pBnaC05g31880D具有驱动GUS报告基因在拟南芥各个组织中组成型表达的特性。这为该启动子在油菜转基因提高作物品质和人工创建种质资源等方面的应用提供了较好的基础。
