Abstract:
The complete mitochondrial genome of Schizothorax pseudaksaiensis was cloned and sequenced in the present study. The genome was 16,582 bp in size, which had a mostly conserved structural organization in comparison with that of other teleost fish. It consisted of 37 genes (13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes), and 2 main non-coding regions (the control region and the origin of the light strand replication). All protein-coding genes started with ATG except for COX1, which began with GTG. However, the termination codons of 13 protein-coding genes varied with TAA, TA, T or TAG. The overall base composition of S. pseudaksaiensis in descending order was A 30.18%, C 27.08%, T 25.37% and G 17.37%, with a slight A + T bias. The complete mitochondrial genome sequence may provide useful information for phylogenetic analysis and studies of population genetics of S. pseudaksaiensis.
