From: CenH3 evolution in diploids and polyploids of three angiosperm genera
Episodic diversifying selection in Brassica and Oryza , as inferred using MEME. Each phylogeny represents a single codon exhibiting diversifying selection in the specified genus. The scale bar represents distance and EBF is the empirical Bayes factor, which signifies diversifying selection with warm colors and stabilizing selection with cool colors. Particular branches are labeled with numbers, which correspond to the Ka:Ks of a single codon on the right of each phylogeny.
