摘要: 本研究通过生物信息学方法鉴定茶树ABF3基因,利用在线软件ExPASy-ProtParam分析理化性质,利用 SMART分析基因保守结构域,通过同源克隆获得CsABF3基因全长,并进行RT-PCR分析低温胁迫下基因的表 达情况。结果发现,茶树ABF3基因长度1O99bp,基因克隆显示长度几乎一致,SMART基因结构分析显示Cs- ABF3氨基酸结构高度保守,氨基酸序列显示CsABF3和拟南芥ABF3同源性44.30%,同源性较差,说明在功能 上可能与拟南芥具有较大的差异。而低温胁迫下的表达分析也表明,CsABF3受低温诱导表达显著下降,在恢复 后表达恢复正常。本研究通过实验分析初步认为该基因可能参与植物低温胁迫信号调控通路。
