Genetic relationships of Iranian coastline ship sturgeon (Acipenser nudiventris) samples and Ural population based on microsatellite DNA.

Genetic relationships among 96 specimens of ship sturgeon, acipensernudiventris, collected from six locations along the iranian coastline as well as 8 specimens from northern population (ural river) were analysed by the restricted maximum likelihood method, as well as two distance analysis method (nei's and cavalli-sforza's distance) of gene frequencies. we have used four ssr makers that produced three polymorphic and two monomorphic loci. overall results showed thatiranian coastline samples form a monophyletic group (clade) which was different from the northern (ural) samples. iranian coastline samples are divided into two groups (clades): anzali-kiashahr clade and sefidrud-babolsar-noushahr-gorgan clade. bootstrapping test showed monophyleticity of sefidrud, babolsar, noushahr, gorgan with high (bootstrap support=93) and anzali-kiashahr with middle (bootstrap support=65) confirmation. topology of reconstructed trees was incorrespondence with geographical distributions of samples.
