Sequence and organization of the complete mitochondrial genome of the Ussuri mamushi (Gloydius ussuriensis)

Abstract

The mitochondrial genome sequence of Ussuri mamushi is analyzed and presented publically for the first time. The genome is 17,208 bp in length and contains 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and 2 control regions. The overall base composition is A (32.4%), C (28.4%), T (26.3%) and G (12.9%). The base compositions clearly presented the A-C skew, which is the most obvious in the protein-coding genes. Mitochondrial genome analyses based on MP, ML, NJ and Bayesian analyses yielded identical phylogenetic trees, indicating a close phylogenetic affinity of the 13 Crotalinae species. It appeared that no less than two major phyletic lineages were present in Crotalinae. The main clades within the Crotalinae include Protobothrops. A clade (G. brevicaudus, G. ussuriensis, G. intermedius, and G. sahatilis) with the Ovophis as the sister taxon to Protobothrops was supported by bootstrap values of 88%. The four Gloydius species formed a paraphyletic group with the high bootstrap value (100%) in all examinations.
