摘要 NAC(NAM,ATAF1/2和CUC2)转录因子家族为植物所特有,该家族成员在植物生长发育及对环境胁迫的应答中有重要的调控作用.近年来,NAC家族中一类被命名为NTLs(NTM1-Like)的膜系留转录因子受到了研究人员的重视.拟南芥中ANAC089编码具有340个氨基酸的NAC蛋白,在它的C-末端有一个预测的跨膜结构域.亚细胞定位表明,全长的ANAC089蛋白定位在内质网,而截去跨膜结构域的截短蛋白ANAC089 ΔC定位在细胞核内.长日照条件下,35S::ANAC089ΔC转基因植株株型矮小、叶片小而浓绿,最为明显的是开花延迟.与此表型相应,转基因植株中CO,SOC1,FT和LFY的表达水平受到了不同程度地抑制,而FLC的表达水平被增强.本研究表明,ANAC089是一个膜系留转录因子,以截短蛋白ANAC089ΔC的形式进入细胞核内执行转录因子的功能,ANAC089在拟南芥的开花诱导过程中起负调控作用.
