The complete mitochondrial genomes of two imperiled species endemic to the Southwestern United States: Peppered Chub (Macrhybopsis tetranema) and Gila Trout (Oncorhynchus gilae)

Abstract

Macrhybopsis tetranema and Oncorhynchus gilae are fish species endemic to the Southwestern United States. We present the complete mitochondrial genomes for these species. Each genome consisted of 13 protein-coding genes, two ribosomal (rRNA) genes, 22 transfer RNA (tRNA) genes, and the control region (D-loop). Mitogenome lengths were 16,916 base pairs (bp) for M. tetranema , and 16,976 bp for O. gilae. The GC content was 41% for M. tetranema and 46% for O. gilae . The relationships of M. tetranema and O. gilae were consistent with previous phylogenetic analyses.
