Phylogenetic analysis of the MA3 domains of A. thaliana PDCD4 proteins suggests domain duplication. A phylogenetic tree of the MA3 domains of A. thaliana MAT5-8 proteins was constructed using the maximum-likelihood method. Numbers on each branch denote percentages of bootstrap support. MA3 domains 2 and 4 of each MAT protein are shaded light blue whereas MA3 domains 1 and 3 are shaded dark blue.
