Characterization of the complete mitogenome for the freshwater shrimp Exopalaemon modestus.

Natural resources of the freshwater shrimp Exopalaemon modestus declined sharply in China in recent years. However, available genetic information for this shrimp is quite limited presently. In this study, the complete mitochondrial genome of E. modestus was firstly determined through Illumina sequencing. The mitogenome is 15,736 bp in length containing 13 protein-coding genes, 22 tRNA genes, two rRNA genes and one control region. Twenty-three of these genes were encoded by the H-strand and the remaining 14 ones by the L-strand. Additionally, compared to gene orders of other Caridea, a novel rearrangement of translocation between tRNA^Pro and tRNA^Thr was detected in E. modestus. The mitogenomic information obtained herein will be useful for future studies on population genetic and phylogenetic analyses of this shrimp. [ABSTRACT FROM AUTHOR]
