Genetic Analysis of Annular Sea Bream (Diplodus annularis Linnaeus, 1758) Populations Based on mtDNA Cyt b Gene in Turkey
Abstract
Considering its
importance and lack of information on its genetic structure, in this study, population genetic structure and genetic diversity of the annular seabream Diplodus
annularis (L.) in the Turkish Seas was determined using the partial sequence of mitochondrial DNA cytochrome b gene (997 bp). Localities where annular
seabream samples collected were as follows: the eastern Mediterranean Sea (Adana), the western Mediterranean Sea (Antalya), the Aegean Sea (İzmir), the
Marmara Sea (Canakkale and İstanbul), Mid-Black Sea (Sinop) and the Eastern Black Sea (Rize). The population genetic structure was estimated through
pairwise FST, analysis of molecular variance and phylogenetic analyses (NJ, MP, ML and BI). As a result the genetic variability was low among the population
based on haplotype and nucleotide diversities of cytochrome b gene. However, phylogenetic analyses of the cyt b haplotypes showed up there are two possible
genetic groups (the Aegean-Mediterranean and Marmara-Black Sea) suggesting that the presence of restricted migration at the Straits of Dardanelles, separating
the Aegean and Marmara Seas.
