摘要:
为了探讨中国境内红毛菜的物种关系及亲缘关系,对红毛菜核糖体基因的28S rDNA、IGS序列进行了研究。28S rDNA序列分析结果显示:江苏(LYG、NT)、福建(NRD1、NRD2)、广东(NA1、NA2、NA3)的7个海水红毛菜遗传距离为0~0.004;而威海(WH)的海水红毛菜与其他海水红毛菜的遗传距离为0.144~0.147;山西娘子关(NZG)、甘肃兴隆山(XLS)的2个淡水红毛菜之间的关系极近,遗传距离为0.001;淡水红毛菜与威海的海水红毛菜的遗传距离(0.125)小于淡水红毛菜与其他7个海水红毛菜的遗传距离(0.210~0.213)。对江苏、福建、广东的7个海水红毛菜的IGS序列进行分析显示,7个海水红毛菜亲缘关系极近。基于28S rDNA序列的系统进化树显示,中国境内采集到的红毛菜分为3个进化分支:2个淡水红毛菜形成独立1支,而海水红毛菜则分为2个进化分支,其中威海的海水红毛菜单独为1个分支,其他7个海水红毛菜归为另1个分支。由此推测,目前为止中国境内至少存在3种红毛菜。
