Description and phylogenetic implications of a de novo mitochondrial genome of Rhinichthys atratulus (Teleostei: Leuciscidae) from Connecticut.

ABSTRACT: We present a de novo mitogenome assembly from a specimen of Rhinichthys atratulus, the Eastern Blacknose Dace, collected in the Connecticut River drainage. R. atratulus is a fish species widely distributed across Atlantic slope drainages from Nova Scotia, Canada to the Roanoke River Drainage, Virginia, United States. The assembly has a total length of 16,646 bp; consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a 974 bp D-loop; and has a GC content of 45.7%. We performed two phylogenetic analyses using the de novo assembly and 28 additional cyprinoid mitochondrial genomes: with and without the D-loop. The resulting phylogenetic trees showed the same branching patterns. However, inclusion of the D-loop resulted in nodes with equal or greater support. The trees largely ma
