摘要:
FLC基因是MADS-box家族的重要成员,参与调控植物花芽分化和开花过程,在春化作用中起关键作用。以拟南芥(Arabidopsis thaliana)FLC基因编码蛋白序列(GenBank登录号:AAN04056.1)为探针,运用电子克隆方法获得蓝莓(Vaccinium spp.)FLC基因(VaFLC)cDNA序列,对其编码蛋白的理化性质、亲/疏水性、保守序列、二级结构和三级结构特点进行预测分析,并对该编码蛋白与其他植物中FLC基因编码蛋白的相似性和进化关系进行研究。结果表明,蓝莓FLC基因cDNA全长1 303 bp,包含1个长度为753 bp的完整开放阅读框,编码250个氨基酸,编码蛋白含有MEF2-like MADS域、I域、K域和C域4个明显的结构域,属于MADS-box基因家族中植物Ⅱ型(MIKC型)基因。在蓝莓FLC基因编码VaFLC蛋白与其他植物FLC蛋白的相似性方面,除与大豆的相似性为38%之外,与其他植物的相似性均高于40%,其中与葡萄、柑橘具有47%的相似性,与拟南芥、可可树、白桦具有46%的相似性,与梨树具有45%的相似性。蓝莓VaFLC蛋白在系统进化树上归为木本植物分支,并形成独立的小分支,推测该基因及其编码蛋白在植物FLC进化过程中保留了部分原始特征。
