Site-specific positive selection pressure.

Sites marked in bold are positive selected sites that meet the criteria of all applied methods. Underlined sites are positive selected sites that agree with the G gene and full genome analysis. RC = Renaissance Counting, FEL = Fixed-Effect Likelihood, REL = Random-Effects Likelihood, dN = non-synonymous substitution, dS = synonymous substitution and log(BF) = Bayes Factor logarithm. REL could not be acquired for the whole genome data set (N/A).
