AI Article Synopsis

  • - The mitochondrial genome of the Himalayan coldwater fish Schizothorax richardsonii was sequenced for the first time, totaling 16,592 base pairs and containing key genetic components like 13 protein-coding genes, 22 tRNAs, and 2 rRNA genes.
  • - The arrangement of these genes is similar to other vertebrates, with a base composition of A: 29.9%, G: 17.7%, C: 26.9%, and T: 25.5%, leading to A + T content of 55.4% and G + C content of 44.6%.
  • - A notable feature of the genome is a microsatellite

Article Abstract

The complete mitochondrial genome of Schizothorax richardsonii, an endemic coldwater fish of Himalayas, was determined for the first time. The genome is 16,592 bp in length and consists of 13 protein coding genes, 22 tRNAs, 2 rRNA genes and one putative control region. The gene organization and its order were similar to other vertebrates. The overall base composition was as follows: A: 29.9%, G: 17.7%, C: 26.9%, T: 25.5%, A + T content 55.4% and the G + C content 44.6%. The control region contains a microsatellite; (TA)13 exists between 16,469 and 16,494 bp. This study will provide the rationale for the management and conservation of the snow trout.
