Revision of nucleotide substitution rate in mtDNA control region of white sturgeon Acipenser transmontanus (Acipenseridae) [PDF]

open access: greenarXiv, 2017
The raw data from study of variation of D-loop mtDNA of white sturgeon Acipenser transmontanus (Mol. Biol. Evol. 1993. 10: 326-341) was re-analyzed. Re-calculated nucleotide substitution rate ({\mu}) was 0.782-0.939 x 10-7 substitutions/site/year/lineage, which was 1.4 times less than the estimate given in above-mentioned publication.
