摘要(Abstract)：

通过ITS基因特异扩增测序,对大鹏半岛海域46种石珊瑚ITS基因片段序列进行了比较分析。结果表明,该片段序列长度在674~806碱基对(bp)之间,A、T含量在40%~55.5%之间,大部分物种的序列碱基A、T含量小于G、C含量。46种造礁珊瑚的平均遗传距离为0.261。采用邻位连接(NJ)和最小进化(ME)法分别构建15种复合型珊瑚的5.8S r DNA系统发育树和28种坚实型珊瑚的ITS2系统发育树,结果显示15种复合型珊瑚的5.8S r RNA序列系统进化聚类结果较符合传统形态学分类结果,而28种坚实型珊瑚的ITS2序列系统进化聚类结果与传统形态学存在较大的差异,提示石珊瑚表型的变异性可能对传统分类存在影响。
