摘要利用全基因组序列数据测定了海洋食木等足类甲壳动物四点浮萍的线粒体全基因组。该基因组全长16,503个碱基，包含39个基因：13个蛋白质编码基因，2个核糖体RNA基因，22个tRNA基因，其中两个重复序列和一个控制区。粘虫蛋白编码基因最常用的起始密码子是ATN，在另外两个可用的完整等足目有丝分裂基因组中也是如此。这些完整的等足目有丝分裂基因组之间的基因排列不同，H链蛋白编码基因的AT-含量也不同。后者的观察结果，加上在等足目有丝分裂体间观察到的相当大的核苷酸多样性，支持了这样的观点，即每个等足类物种都属于不同的谱系，正如它们目前位于不同的亚目中所暗示的那样。
Abstract The complete mitochondrial genome of Limnoria quadripunctata, a marine wood-eating isopod crustacean, was determined from whole genome sequence data. The mitogenome is 16,503 bp in length and contains 39 genes: 13 protein-coding, 2 ribosomal RNA, 22 tRNA, two of which are repeated and a control region. The start codon most commonly used by the Limnoria protein-coding genes is ATN, as is the case in the two other available complete isopod mitogenomes. The gene arrangement differs among these complete isopod mitogenomes, as does the AT-content of H-strand protein-coding genes. The latter observations, coupled with the considerable nucleotide diversity observed between the isopod mitogenomes, support the idea that each isopod species belongs to a distinct lineage as implied by their current placement in separate suborders.
