schizothoracine High altitude adaptation mitochondrial genome
摘要：

The schizothoracine fishes, also known as "mountain carps" are widely distributed in the Qinghai-Tibetan Plateau and its peripheral regions. Although they provide a prime example of high altitude adaptation, the phylogenetic relationships and the divergence times among these carp lineages are still controversial. Moreover, the genetic basis for high altitude adaptation is also poorly understood. In this study, we determined the mitochondrial genomes from two species of the schizothoracine fishes, representing a "morphologically primitive" clade and "morphologically specialized" clade, respectively. The phylogenetic tree and the divergence times were estimated within the evolutionary framework of the entire order Cypriniformes. Our results indicate a polyphylyetic relationship of the schizothoracine fishes and suggest two independent migration events into the Qinghai-Tibetan Plateau: one by the "morphologically primitive" clade in the Late Miocene and another by the "morphologically specialized" clade in the Eocene. Rapid speciation evenrs of each clade from the Late Miocene to the Pliocene correspond to the timing of the geologic acceleration of the Qinghai-Tibetan Plateau. Interestingly, we found evidence for positive selection acting on the protein coding genes in the mitochondrial genomes of the "morphologically specialized" clade, implying a possible genetic basis for high altitude adaptation in this derived lineage of cypriniform fishes.
