In this study we determined the complete mitochondrial genome (mitogenome) of the Chinese swamp shrimp Neocaridina denticulata sinensis Kemp, 1918 (Decapoda, Atyidae). The mitogenome consists of 15,561 bp encoding 37 genes that are involved in mitochondrial protein synthesis as well as respiration chain/oxidative phosphorylation. Besides, a 672-bp putative control region was identified between the small subunit ribosomal RNA and tRNA-Ile genes, the size and AT content of which is moderate within the Decapoda. The gene arrangement of the mitogenome follows the pancrustacean ancestral pattern shared by the decapod subfamily Dendrobranchiata, pleocyematan infrafamilies Caridea and Palinura. Our results will provide important data for various levels of phylogeny and further evolution.
在本研究中,我们测定了中华沼虾(Neocaridina denticulata sinensis Kemp,1918)(十足目,匙指虾科)的完整线粒体基因组(线粒体基因组)。该线粒体基因组由15,561 bp组成,编码37个参与线粒体蛋白质合成以及呼吸链/氧化磷酸化的基因。此外,在小亚基核糖体RNA和tRNA-Ile基因之间鉴定出一个672 bp的假定控制区,其大小和AT含量在十足目内适中。该线粒体基因组的基因排列遵循十足目亚科枝鳃亚目、腹胚亚目下的虾总科和龙虾总科共有的泛甲壳动物祖先模式。我们的结果将为各级系统发育和进一步进化提供重要数据。
