%X 摘要： 运用PCR技术对皱纹盘鲍(Haliotis discus hannai)、黑足鲍(H.iris)和黑唇鲍(H.rubra)3种鲍16S rRNA基因扩增,纯化后测序。结果表明:皱纹盘鲍、黑足鲍和黑唇鲍序列长度分别为544、546、550 bp,序列AT含量分别为58.1%、56.1%和55.9%,三者序列同源性高达94.18%,碱基变异位点分别集中在9~34 bp、248~295 bp、326~375 bp。所得结果与Genebank中22种鲍相应序列进行对比分析,25种鲍遗传距离距离在0.00~0.14之间;用NJ和ML法绘制系统发育树分析其亲缘关系,结果表明鲍科系统发育呈现出一定的区域性,并且染色体数目相同的物种容易聚为一支。<br>Abstract: PCR method was used for amplification of mitochondrial 16S rRNA gene from H.discus hannai, H.iris and H.rubra, and all of amplicons were purified and sequenced. The results showed that 16S rRNA gene sequences with length of 544, 546 and 550 bp were obtained from H.discus hannai, H.iris and H.rubra, the content of A+T were 58.1%, 56.1% and 55.9% respectively, the mutual homology among them was 94.18%, the variation of the sequences focuses on the three regions: 9-34 bp, 248-295 bp and 326-375 bp. The cluster dendrograms of the three collected abalones and 22 abalones from GenBank data based on 16s rDNA were analysed, their genetic distance ranges from 0.00 to 0.14. The phylogenetic tree was constructed with NJ and ML methods to reveal the evolutionary relationships, the results showed that the phylogeny of Haliotide was easy to cluster in one clade when distributed in same district and had same chrosome numbers
