BACKGROUND
Caridina pseudogracilirostris is a highly adaptive estuarine species found in brackish waters and marshes along the southwestern and southern coastal regions of India.
METHODS AND RESULTS
The whole mitochondrial genome of C. pseudogracilirostris is 15,451 bp in length with 59.3% AT content and encodes 37 genes, including 22 tRNAs, 13 protein-coding genes, and two rRNAs, which are arranged in a distinctive pattern similar to most crustaceans. ML and BI methods were used for phylogenetic analysis of C. pseudogracilirostris clustered with other Caridina species, supporting the monophyly of the Caridina genus within the Atyidae family. The fully annotated mitochondrial genome of C. pseudogracilirostris was submitted to GenBank under accession number OQ534868.1.
CONCLUSIONS
We are the first to report on the C. pseudogracilirostris whole mitochondrial genome, which provides a valuable resource for future research on genetics, evolution, phylogenetics, etc., among Caridina species and other species. The phylogenetic investigation supports the monophyly of the Caridina genus within the Atyidae family and emphasizes the value of mitochondrial genome data in determining the evolutionary relationships among crustaceans.
背景
Caridina pseudogracilirostris 是一种高度适应咸淡水和红树林沼泽环境的河口物种，分布于印度西南和南部沿海地区。
方法和结果
C. pseudogracilirostris 的整条线粒体基因组长 15451bp，A+T 含量为 59.3%，编码 37 个基因，包括 22 个 tRNA、13 个蛋白质编码基因和 2 个 rRNA，其排列方式与大多数甲壳类动物相似。基于 ML 和 BI 方法的系统发育分析表明，C. pseudogracilirostris 与其他 Caridina 物种聚类，支持 Caridina 属在 Atyidae 科内的单系性。C. pseudogracilirostris 的全注释线粒体基因组已提交给 GenBank，登录号为 OQ534868.1。
结论
我们首次报道了 C. pseudogracilirostris 的整条线粒体基因组，为 Caridina 属和其他甲壳类动物的遗传、进化、系统发育等方面的后续研究提供了有价值的资源。系统发育研究支持 Caridina 属在 Atyidae 科内的单系性，并强调了线粒体基因组数据在确定甲壳类动物进化关系方面的重要价值。
