Results of the Branchsite analysis. ^{a }Lineages defined as foreground in the branchsite analysis (Figure 5). ^{b }The number in parenthesis indicates the Pvalues under the onesided test with the asymptotic null distribution (a 50:50 mixture of point mass 0 and χ^{2}) in [77]. ^{c }Amino acid position numbering according to the MSA in Figure 2. Amino acid positions involving changes in the physicochemical properties influenced by positive selection are highlighted in bold. BEB, Bayes Empirical Bayes results [78].
