| mitochondrial cytochrome b sequence variation and phylogenetics of the highly specialized schizothoracine fishes (teleostei: cyprinidae) in the qinghai-tibet plateau. | the complete 1140 bp mitochondrial cytochrome b sequences were obtained from 39 individuals representing five species of all four genera of highly specialized schizothoracine fishes distributed in the qinghai-tibet plateau. sequence variation of the cytochrome b gene was surveyed among the 39 individuals as well as three primitive schizothoracines and one outgroup. phylogenetic analysis suggested that the group assignment based on 1140 bp of the cytochrome b sequence is obviously different from ... | 2006 | 16941235 |
