摘要:
无色花青素还原酶(leucoanthocyantin reductase,简称LAR)基因是植物原花色素的一个关键基因。本研究根据已经报道的LAR基因的序列设计兼并引物,采用3′RACE和5′RACE方法,从芒果(Mangifera indica)果实中克隆得到1个LAR基因,其全长cDNA序列为1 221 bp。该基因开放阅读框为1 059 bp,编码352个氨基酸,等电点为578,分子质量为38.38 ku。利用生物信息学在线分析软件对该蛋白组成成分、疏水性/亲水性、二级结构、功能结构域以及三级结构进行预测和分析。通过系统发育分析发现,该基因编码的蛋白与棉花、葡萄、蓝莓、柿等具有较近的亲缘关系;对不同芒果品种的LAR基因的表达进行分析发现,绿色的桂七品种中表达量较高,而黄色的金煌品种中表达量较低。
