摘要：
Complete nucleotide sequence of mitochondrial genome (mitogenome) of the Catla catla (Ostariophysi: Cypriniformes: Cyprinidae) was determined in the present study. Its length is 16,594 bp and contains 13 protein coding genes, 22 transfer RNAs, two ribosomal RNAs and one non-coding control region. Most of the genes were encoded on the H-strand, while the ND6 and eight tRNA (Gln, Ala, Asn, Cys, Tyr, Ser (UCN), Glu and Pro) genes were encoded on the L-strand. The reading frames of two pair of genes overlapped: ATPase 8 with 6 and ND4L with ND4 by seven nucleotides each. The main non-coding region was 929 bp, with three conserved sequence blocks (CSB-I, CSB-II, and CSB-III) and an unusual simple sequence repeat, (TA)7. Phylogenetic analyses based on complete mitochondrial genome sequences were in favor of the traditional taxonomy of family Cyprinidae. In conclusion present mitogenome of Catla catla adds more information to our understanding of diversity and evolution of mitogenome in fishes.
