从水稻中分离获得的一个新的、功能未知的MYB基因,序列分析发现是一个典型的R2R3-MYB转录因子,与拟南芥中的MYB106高度同源,因此命名为OsMYB106。亚细胞定位检测结果表明,OsMYB106蛋白定位于细胞核中。Real Time PCR结果显示OsMYB106在...从水稻中分离获得的一个新的、功能未知的MYB基因,序列分析发现是一个典型的R2R3-MYB转录因子,与拟南芥中的MYB106高度同源,因此命名为OsMYB106。亚细胞定位检测结果表明,OsMYB106蛋白定位于细胞核中。Real Time PCR结果显示OsMYB106在水稻幼穗时期表达最高,并且受干旱、盐处理和冷胁迫的显著诱导上升表达。OsMYB106RNAi抑制植株表现出矮化以及花粉败育。基因表达分析显示花粉发育相关基因OsMS2和CYP704B2在抑制植株中表达显著降低,揭示OsMYB106可能是通过调控OsMS2和CYP704B2介导花粉细胞壁的发育进而影响花粉的育性。展开更多
