C, G and Restriction Endonuclease (ALU I, NHE I, HAE III, MBO I, HINF I) Banging of The Chromosomes in Acanthalburnus microlepis (DE FILIPPI, 1863) Endemic to Kura-Aras River Basin
Öz
Chromosome numbers and the standard karyotypic details for the Blackbrow bleak, Acanthalburnus microlepis, (De Filippi, 1863) (Fam: Cyprinidae) were ascertained. The fish used in this study were caught by electrofishing from the Kura-Aras river basin (Çıldır Lake) and taken to the laboratory. Fishes were injected intraperitoneally (i.p.) with doses of 0.01 ml/g body weight of 0.6 % solution of colchicine and left for 190 minutes before sacrification. It was determined that A. microlepis had 2n=50 chromosomes by metaphase investigation. Their karyotypes were determined as being composed of 8 metacentric, 7 submetacentric and 10 acrocentric chromosome pairs with NF: 80. We were unable to identify any sexrelated chromosomes in this species. A. microlepis chromosomes were treated with 5 restriction endonucleases stained with Giemsa and examined for banding patterns. The enzymes Alu 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 the those G-bands. The restriction endonucleases markedly reduced the extent of Giemsa staining. For the first time, it is this study that determined in detail the karyotype of the endemic cyprinid fish in the Kura-Aras river basin.
