摘要: 为了发掘小麦育性基因,采用同源克隆的方法,从小麦花药中克隆了3个与拟南芥 AtMS2 和水稻 OsMS2 基因同源的cDNA序列。 TaMSR-1TaMSR-2TaMSR-3 分别具有1 842,1 824,1 830 bp 的开放阅读框,各自编码613,607,609个氨基酸。推导的蛋白质序列中包含2个保守区:NAD_binding 和Sterile保守功能域。氨基酸序列分析发现,TaMSR与水稻OsMSR2和拟南芥AtMSR2具有较高的相似性。采用基因特异定位引物PCR技术对中国春缺失系材料进行扩增,将 TaMSR-1TaMSR-2TaMSR-3 基因分别定位于4AS、4DL和4BL染色体上。半定量RT-PCR分析表明,TaMSR基因是花药组织特异表达的基因。这些结果说明,TaMSR基因可能在小麦花药发育过程中起重要作用。

Abstract: In search for fertility gene in wheat,three cDNAs that homologous to AtMS2 and putative OsMS2,designated as TaMSR-1, TaMSR-2 and TaMSR-3 were cloned from wheat anther by homologogy-based cloning approach. TaMSR-1, TaMSR-2 and TaMSR-3 contain open reading frames of 1 842,1 824,1 830 bp encoding proteins of 613,607,609 amino acid residues including two male sterile conserved domains:NAD-binding domain and male sterile C-terminal domain,respectively.The deduced amino acid sequence of TaMSR had high similarities with OsMSR2 and AtMSR2.Using Chinese_Spring_Deletion line, TaMSR-1, TaMSR-2 and TaMSR-3 genes were located on chromosome 4AS,4DL and 4BL,respectively.Semi-quantitative RT-PCR analysis revealed that TaMSR gene was anther specific expressed gene.These results suggested that TaMSR may plays an important role in wheat anther development.
