Fig. 1From: Exceptionally high rates of positive selection on the rbcL gene in the genus Ilex (Aquifoliaceae)Variable codons (91 to 436) found among 116 Ilex sequences (Worldwide dataset) mapped on the accession I. canariensis_90, as reference. Uncolored codons are synonymous substitutions. Yellow codons are non-synonymous substitutions. # means positively selected codons (Bayesian posterior probability > 0.95 using the M8 model of Codeml, PAML (Table 1). + means positively selected residues found among the 20 most often positively selected residues of [29] (Table 1). § means residues involved in coevolution (Table 4)Back to article page
