Özet
Türk deniz sularından beş tirsi türünün (Alosa caspia, A. fallax nilotica, Alosa maeotica, Alosa immaculata, Alosa tanaica) filogenetik ilişkisi mitokondriyal DNA polimeraz zincir reaksyionu-restriksiyon parça uzunluk polimorfizmi ile araştırılmıştır. PCR ile uygulamaya tabi tutulmuş altı gen bölgesi; NADH 5/6, NADH 3/4 cytochrom b, COX, 16 S rRNA ve D-Loop, yedi restriksiyon enzimi ile (BsurI, AluI, EheI, Hin6I, RsaI, XhoI Bsh1236I) sırasıyla kesilmiştir. Filogenetik analiz için bir araya getirilmiş altı genden toplam 45 haplotip beş tirsi türünden tespit edilmiş ve ortalama haplotip çeşitliliği ile türler içerisindeki nükleotit çeşitliliği sırasıyla 0,8809 ve 0,0022 olarak bulunmuştur. En yüksek genetik farklılık A. caspia ve A. maeotica (0,013727) arasında, en düşük A. immaculata ve A. tanaica (0,003073) arasında gözlenmiştir. Monte Carlo (X 2 ) ikili genetik karşılaştırma sonucunda tüm türler arasında yüksek derecede önemli farklılıklar ortaya çıkmıştır (P<0,001). Komşu katılımlı ağaçta oluşan iki ana grupta; birinci grup A. caspia ve A. f. nilotica genetik benzerlik olarak birbirine çok yakın görülürken, A. immaculata.bu gruba kardeş grup olmuştur. A. tanaica ise bu grubun içerisinde bir hayli farklı görünmektedir. Alosa cinsi arasında en yüksek genetik farklılaşma gösteren A. maeotica sadece diğer grup içerisinde yer almıştır.
The phylogenetic relationship among five shad species (Alosa caspia, A. fallax nilotica, Alosa maeotica, Alosa immaculata, Alosa tanaica) from Turkish marine waters was investigated with mitochondrial DNA polymerase chain reaction-restriction fragment length polymorphism.The six genesegments, NADH 5/6, NADH 3/4cytochrome b, COX, 16 SrRNA and D-Loop, of mtDNA amplified by PCR were digested with seven restriction enzymes, BsurI, AluI, EheI, Hin6I, RsaI, XhoI Bsh1236I, respectively.When all the six genes were combined together for phylogenetic analysis, a total of 45 haplotypes were detected from the five shad species, and the average haplotype diversity and nucleotide diversity within species were 0.8809 and 0.0022 respectively. The average nucleotide diversity and nucleotide divergence among species were 0.009248 and 0.007080 respectively. The highest genetic divergence was observed between A. caspia and A. maeotica (0.013727) and the lowest between A. immaculate and A. tanaica (0.003073). Monte Carlo (X 2 ) pairwise genetic comparison revealed highly significant differences between all species (P<0.001). In the Neighbour-joining tree, there were two main grouping, and in the first group, A. caspia and A. f. nilotica exhibited the closest genetic similarity which was the sister group to A. immaculata. A .tanaicaseems to be the most divergent in this grouping. Another group contained only A. maeotica which showed the highest genetic differentiation among Alosa genus.
