Complete mitochondrial genome and phylogenetic analysis of Uca Borealis

Abstract

In this study, the complete 15,662 bp mitochondrial genome was determined from Uca borealis using next-generation sequencing technology. It consists of 13 protein-coding genes, 22 tRNAs, 2 ribosomal RNAs, and a control region. Among the 37 genes, 23 genes (9 PCGs and 14 tRNA genes) are encoded on the heavy (+) strand while the remaining 14 genes (four PCGs, eight tRNA genes and two rRNA genes) are located on the light (−) strand. The AT-skew (0.01) for the whole mitogenome is slightly positive while GC-skew (−0.25) is negative, indicating a higher occurrence of As than Ts and Cs than Gs. The phylogenetic tree was constructed using MrBayes method based on the PCGs showed the present species clustered within the Brachyura. The complete mitogenome data would be useful for further study of U. borealis.
