Phylogenetic relationships of Cultrinae species
A total of 668 sequences of the complete
cytochrome b gene (1,140 bp) were
obtained, and 171 haplotypes were identified. Based on these haplotypes,
BI tree and ML tree yielded congruent topologies and consistently
supported C. erythropterus was sister species to C.
mongolicus , C. dabryi sister to C. alburnus , and H.
leucisculus sister to H. bleekeri ; then H. leucisculus +H. bleekeri sister to Pseudolaubuca sinensis (Fig.
6).
