Mitochondrial DNA B Resour. 2017 Sep 4;2(2):613-614. doi: 10.1080/23802359.2017.1372727.
The complete mitochondrial genomes are sequenced in two individuals representing two morphological forms, 'usual' (U) and 'gray' (G), of the short-spined sea urchin . The genome sequences are 15,705 bp in size, and the gene arrangement, composition, and size are very similar to the other sea urchin mitochondrial genomes published previously. A low level of sequence divergence ( = 0.0083 ± 0.0007) is detected between the forms. The GenBank (KC490912) mt genome of is much closer to the U form ( = 0.0013 ± 0.0003) than to the G form ( = 0.0085 ± 0.0006), demonstrating unique evolutionary trajectories for each form, which we previously suggested based on the gene and symbiont analyses.
对代表短棘海胆两种形态类型“普通型”(U)和“灰色型”(G)的两个个体的线粒体全基因组进行了测序。基因组序列大小为15,705 bp,其基因排列、组成和大小与先前发表的其他海胆线粒体基因组非常相似。在这两种形态类型之间检测到低水平的序列差异(= 0.0083 ± 0.0007)。GenBank(KC490912)的线粒体基因组与U型(= 0.0013 ± 0.0003)的亲缘关系比与G型(= 0.0085 ± 0.0006)更近,这表明每种形态类型都有独特的进化轨迹,这是我们之前基于基因和共生体分析所提出的。
