【摘要】:[目的]本文旨在克隆菊花‘神马’Cm14-3-3υ基因,并初步分析其表达特征,为其功能研究奠定基础。[方法]从菊花‘优香’转录组库中获得编码拟南芥同源基因14-3-3υ序列信息,根据NCBI比对确定基因的cDNA全长并进行克隆,再利用生物信息学方法对该蛋白的功能和活性位点进行预测,同时利用实时定量PCR分析了在非生物胁迫条件下该基因的表达变化。[结果]Cm14-3-3υ的ORF序列长774 bp,编码257个氨基酸;亚细胞定位表明Cm14-3-3υ定位在细胞质和细胞核;生物信息学分析表明该蛋白有19个Ser、7个Thr和7个Tyr潜在的磷酸化位点,在N-端有5个蛋白结合区;表达模式分析显示,Cm14-3-3υ基因在根、茎、叶、花中均有表达,且受脱落酸(ABA)、茉莉酸甲酯(Me JA)、盐和冷胁迫的诱导表达。[结论]本文克隆得到菊花Cm14-3-3υ基因,表达模式分析表明其受ABA、Me JA、盐和冷胁迫诱导表达。
