Intraspecific mitochondrial variations between Rhinogobio typus from the Yellow River and Yangtze River

Abstract

The complete mitochondrial genome of the first individual Rhinogobio typus collected from the Yellow River were sequenced and compared with the previously reported complete mitochondrial sequence of Rhinogobio typus from the Yangtze River. The length of their circular mitochondrial genome was determined to be 16 599 and 16 608 bp respectively. The comparison of two mitochondrial genomes revealed 237 base pair substitutions and 17 insertions or deletions (indels), including 182 base pair substitutions and 2 indels in protein-coding region. Phylogenetic tree was constructed based on complete mitogenomes of the two populations and closely related 13 teleost species to assess their phylogenic relationship and evolution.
