Abstract
Sequences of the partial 293-bp nuclear Z-chromosome-linked chromo-helicase binding protein ( CHD-Z) and 729-bp mitochondrial cytochrome b ( cyt b) genes were obtained from two species of the same family Pycnonotidae of Pycnonotus sinensis ( P. sinensis, Chinese Bulbul) and Pycnonotus taivanus ( P. taivanus, Taiwan Bulbul) distributed in Taiwan. A panel of 10 individuals ( n = 5 for each) with unknown relationship was used to characterize single nucleotide polymorphisms (SNPs) of these genes. We identified 2 and 10 SNPs in CHD-Z and cyt b loci, respectively. Frequency of SNPs was 10 per every 1465- and 729-bp on average. Pairwise nucleotide divergences of CHD-Z and cyt b genes among 10 specimens ranged from 0 to 0.0034 and 0 to 0.0055, respectively. Phylogenetic analysis suggested that the P. taivanus group assignment based on the CHD-Z and cyt b sequences is obviously very similar to P. sinensis.
