小鲵科动物Cytb基因密码子偏好性分析
Codon bias of Cytb genes in Hynobiidae
摘要
Abstract
The codon bias of Hynobiidae Cytochrome b genes among 1 6 species were analyzed by using the software Mobyle online tool CUSP program,CodonW,and Cluster3.0,and a further discussion on the Codon bias effection on phylogenetic analysis was done.The results showed that the ENC(effective number of codons)of these 16 Hynobiidae Cytb genes range from 34.45 to 47.18,with average value at 41.01,which shown a preference on codon bias.The nucleotide base composition analysis at each locus showed Hynobiidae Cytochromeb prefers to codes end by A or T bases.The hierarchical clustering of RSCU values and species showed obvious codon usage patterns among genera. The clustering results slightly deviated from the Maximum-likelihood and the Bayes phylogenetic trees.关键词
