Abstract

Karyotype analysis was performed in Chalcalburnus tarichi specimens by investigating the number and structures of their chromosomes. The fish used in this study were caught with fishing nets from Lake Van and taken to the laboratory. The fish were injected I.p. with 0.01 ml/g body weight doses of a 0.6% solution of a colchicine for 190 min. As a result of the metaphase investigation we determined that C. tarichi had 2n = 50 chromosomes. Their karyotypes were determined to be composed of 8 metacentric, 5 submetacentric and 12 acrocervtric chromosome pairs. We were unable to identify any sex-related chromosomes in this species. C. tarichi chromosomes were treated with 5 restriction endonucleases stained with Giemsa and examined for banding patterns. The enzymes AIu I revealed banding patterns similar to the C-bands produced by treatment with barium hydroxide. The enzymes Hae III, Hinf I, Nhe I and Mbo I revealed banding patterns similar to those of G-bands. The restriction endonucleases markedly reduced the extent of Giemsa staining.

Özet

Sazangiller familyasına ait Chalcalburnus tarichi'nin kromozomlarının sayı ve yapıları incelenerek karyotipleri yapılmıştır. Bu çalışmada kullanılan balıklar Van Gölü'nden ağlarla yakalanarak laboratuvara getirilmiştir. Balıkların karın boşluğuna gramlarına 0,01 mi gelecek şekilde % 0,6'lık kolsişin enjekte edilmiştir. Metafaz incelemeleri sonucunda C. tarichi'rim 2n = 50 kromozoma sahip olduğu belirlenmiştir. Karyotiplerinin ise 8 metasentrik, 5 submetasentrik ve 12 akrosentrik kromozom çiftlerinden oluştuğu saptanmıştır. Bu türde cinsiyetle bağlantılı herhangi bir kromozom tespit edilememiştir. C. tarichi kromozomları beş restriksiyon endonükleazla muamele edilmiş, Giemsa ile boyanmış ve bant örnekleri incelenmiştir. AIu I enzimi baryum hidroksit etkileşimi ile ortaya çıkan C-banda benzer bant örnekleri üretmiştir. Hae III, Hinf I, Nhe /ve Moo /enzimleri ise G-banda benzer bant örnekleri üretmiştir. Restriksiyon endonükleazlar Giemsa ile boyanma oranını belirgin bir şekilde düşürmüştür.
