摘要:
SPL是植物中重要的转录因子,调控植物从幼年期向成年期转变,为探究DdSPL基因在德阳柿成花调控中的作用,为德阳柿实生苗的早花现象提供依据。本研究采用生物信息学方法对德阳柿SPL基因家族成员进行鉴定,并对其基本理化性质、系统进化关系、保守结构域、基因结构、共线性进行分析;通过融合蛋白瞬时表达鉴定亚细胞定位情况;利用qRT-PCR技术检测其在不同成花时期不同部位[茎、叶、顶芽(花)]的表达情况。结果表明,德阳柿中共鉴定得到38条DdSPL基因序列,通过聚类分析可分为8个亚族,同一聚类的蛋白具有相似的氨基酸结构(2个锌指结构ZN-1、ZN-2和1个核定位信号)和基因结构;保守基序分析发现,所有的DdSPL蛋白均含有SBP结构域。共线性分析结果显示,德阳柿38个SPL基因家族成员中存在49对直系同源基因对。亚细胞定位显示,DdSPL8、DdSPL13、DdSPL18均定位在细胞核中;DdSPL7、DdSPL13、DdSPL18这3个基因的表达模式相似,在幼苗期和现蕾期的茎、叶、顶芽(花)中表达量相对较少,在开花期的叶片中表达量明显提高,可能参与德阳柿成花调控。综上,本研究首次从德阳柿基因组中鉴定出38个SPL家族成员,序列高度保守,且均含有SBP结构域,DdSPL7、DdSPL13、DdSPL18在开花期叶片中高表达,可能参与德阳柿成花调控。
