Figure 5From: Positive selection and ancient duplications in the evolution of class B floral homeotic genes of orchids and grassesSites under positive selection in Poales, mapped on the alignment of monocot DEF -like proteins containing only all variable amino-acid positions. The sites with a posterior probability of ≥ 0.90 listed in Table 5 are marked with an asterisk on the alignment. Although the sequences under positive selection correspond to the Poales, the rest of the sequences in the alignment are included for a better comparison.Back to article page
