Abstract

The complete mitochondrial genome was sequenced from the marine water flea Diaphanosoma celebensis. The sequenced mitochondrial genome size was 17,060 bp, possessing identical gene order of 13 protein-coding genes (PGCs) to those of the congeneric freshwater species Diaphanosoma dubium in the genus Diaphanosoma. The mitochondrial genome of D. celebensis had 13 PGCs, two rRNAs, and 22 tRNAs. Of 13 PGCs, three genes (CO3, ND3, and ND4) had incomplete stop codons. Furthermore, the stop codons of the remaining ten PGCs were TAA (for CO1, ATP8, ATP6, ND5, ND6, and ND1) and TAG (for NL4L, Cytb, and ND2). The second and third base composition of codon on 9 PCGs on the L strand in D. celebensis mitogenome showed an anti-G bias (11.0% and 15.0%), respectively.

摘要

完整的线粒体基因组测序的海水蚤Diaphanosoma celebensis。测序的线粒体基因组大小是17060个碱基，具有13个蛋白质编码基因（的PGC）的那些同类淡水物种的相同基因顺序秀体柱木属中的秀体。Celeb.ensis的线粒体基因组具有13个PGC，2个rRNA和22个tRNA。在13个PGC中，三个基因（CO3，ND3和ND4）具有不完整的终止密码子。此外，其余十个PGC的终止密码子为TAA（对于CO1，ATP8，ATP6，ND5，ND6和ND1）和TAG（对于NL4L，Cytb和ND2）。celebensis丝分裂基因组L链上9个PCG的密码子的第二和第三碱基组成分别显示出抗G偏向（11.0％和15.0％）。
