Revision of nucleotide substitution rate in mtDNA control region of white sturgeon
نویسنده
چکیده
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 (μ) was 0.782–0.939 × 10 substitutions/site/year/lineage, which was 1.4 times less than the estimate given in above-mentioned publication. The use of new μ has led to an increase in estimates of long-term female effective population size (Nef) and coalescence times for mtDNA haplotypes, previously calculated for samples of Amur sturgeon A. sсhrenckii and kaluga A. dauricus, but it did not affect the conclusions on the critical state of their natural populations.

Intraspecific DNA sequence variation of the mitochondrial control region of white sturgeon (Acipenser transmontanus).
Intraspecific sequence variation in the D-loop region of mtDNA in white sturgeon (Acipenser transmontanus), a relict North American fish species, was examined in 27 individuals from populations of the Columbia and Fraser rivers. Thirty-three varied nucleotide positions were present in a 462-nucleotide D-loop sequence, amplified using the polymerase chain reaction. Bootstrapped neighbor-joining ...
متن کاملPopulation structure and variation in Persian sturgeon (Acipenser percicus ) from the Caspian Sea as determind from mitochondrial DNA sequences of the control region
Mitochondria1 DNA (mtDNA) control region sequences were analyzed to evaluate the population genetic structure of Persian sturgeon (Acipenser persicus) in Caspian Sea. A total of 45 specimens were collected from the different locations of the Caspian Sea. MtDNA control region was amplified using PCR. Direct sequencing was performed according standard method. The results showed that 12 haplotypes...
متن کاملGenetic diversity in the Persian sturgeon, Acipenser percicus, from the south Caspian Sea based on mitochondrial DNA sequences of the control region
The Persian sturgeon, Acipenser persicus (Borodin, 1897), is an economically important species, which mainly inhabits the Caspian Sea. However, little is known about its population genetic structure. In this study, variation in nucleotide sequences of the mitochondrial DNA (mtDNA) control region of wild stock Persian sturgeon was determined to assess the genetic diversity among different natura...
متن کاملStudy of mtDNA vatriation of Russian sturgeon population from the south Caspian Sea using RFLP analysis of PCR amplified ND5/6 gene regions
PCR-based mtDNA analysis (RFLP) was used for the study of population differentiation in the Russian sturgeon (Acipenser gueldenstaedti). The mtDNA ND5/6 gene regions were amplified using PCR techniques followed by RFLP analysis. 39 different composite haplotypes were detected among 62 specimens. 29 haplotypes were rare occuring only once in two regions (west and east areas of the Southern Caspi...

A partial sequence of the mtDNA ND5 gene region was used for population study in Persian sturgeon (west and east areas of southern Caspian Sea). The result showed that although this approach was informative for phylogenetic study in sturgeon, it was less informative for population study in Persian sturgeon.
