The complete mitochondrial genome of the black-tailed brush lizard Urosaurus nigricaudus (Reptilia, Squamata, Phrynosomatidae)

Abstract

Previous studies using mitochondrial DNA (mtDNA) genes suggest the black-tailed brush lizard, Urosaurus nigricaudus, which is a small-sized lizard from the peninsula of Baja California, Mexico, has 4 deeply isolated mtDNA lineages with sequence divergence ranging from 4% to 11.2%. We present its complete mitochondrial genome. This genome is 17,298 bp long and comprises 2 rRNAs, 22 tRNAs, 13 protein-coding genes, 1 L-strand origin of replication and 1 control region. The overall nucleotide content is A = 34.2%; C = 26.8%; G = 13.5%; T = 25.5%. The gene organization and features agree with the general vertebrate organization and that found in other lizards. The control region is 1909 bp long and is located between tRNA^Pro and tRNA^Phe.
