Abstract

The complete nucleotide sequence of the mitochondrial genome for the Senegal sole Solea senegalensis Kaup was determined. The mitochondrial DNA was 16,659 base pairs (bp) in length. Sequence features of the 13 protein-coding genes, two ribosomal RNAs and 22 transfer RNAs are described. The non-coding control region (1017 bp) was compared with those of the closely related soles Solea solea and Solea lascaris. The typical conservative blocks were identified. A cluster of 42 and 22 tandemly arrayed repeats was detected near the 3' end of control region in S. solea and S. lascaris, respectively. On the contrary, only two (93.8% of haplotypes) or three copies (6.2%) of an 8-bp repeated sequence motif was found in S. senegalensis. Phylogenetic analysis showed that 7 out of 9 of haplotypes bearing three copies grouped in a separate cluster. Possible mechanisms influencing the evolution of control region among soles are discussed.

塞内加尔鳎(Solea senegalensis Kaup)完整的线粒体基因组。鞋底控制区串联重复序列的比较分析。

测定了塞内加尔鳎(Solea senegalensis Kaup)线粒体基因组的全核苷酸序列。线粒体DNA长度为16,659碱基对(bp)。描述了13个蛋白质编码基因、2个核糖体rna和22个转移rna的序列特征。非编码控制区(1017 bp)与亲缘关系较近的Solea Solea sole和lascaris Solea sole进行了比较。确定了典型的保守街区。在单蜱和蛔虫的对照区3′端附近分别检测到42个和22个串联重复序列。相反，senegalensis只发现2个(93.8%)或3个(6.2%)8-bp重复序列基序。系统发育分析表明，9个携带3个拷贝的单倍型中有7个在一个单独的集群中。讨论了影响鞋底控制区演化的可能机制。
