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.
