摘要:
通过已构建的水稻Ac/Ds突变体系,研究分析新型水稻功能基因,为水稻功能基因组学提供分子遗传方面的资源。从构建的水稻Ac/Ds突变体系中,筛选得到性状稳定的矮秆突变体(mutant type,MT)和正常株高回复体(revertant type,RT)。采用热不对称交错PCR(thermal asymmetric interlaced PCR,简称TAIL-PCR)技术,克隆Ds插入的侧翼序列,对该侧翼序列进行NCBI-Blast在线比对,寻找Ds插入基因;同时利用FGENESH、GeneMark.hmm、DNAMAN、SWISS-MODEL等软件分析Ds插入基因的结构和功能。发现Ds插入在水稻第3号染色体上的OSJNBa0054H04.28基因第4外显子上,此基因编码假拟氧化还原酶蛋白(putative oxidoreductase),该蛋白含有1个保守的2OG-Fe(Ⅱ)加氧酶蛋白结构域。同时发现,RT中有Ds发生转座,并留下8个碱基的切离足迹,其转座机制属于“内切酶模式”。后续分析发现,该基因编码的假拟氧化还原酶蛋白可能在GA的合成过程中起重要作用。此基因是一个新的株高控制基因,可能通过编码假拟氧化还原酶蛋白影响GA的合成,从而对水稻株高的维持起到重要作用。
