Table 4.
The genes were sorted into categories by the gene functions, average dN/dS and Ts + Tv values among lineages. The phylogenetic analyses were performed according to these gene groups in order to determining whether the gene function, selection force and nucleotide substitution rate impact phylogenetic estimation [41].
