Molecular phylogenies of serine peptidases (A) and the DN17 subfamily of CRN proteins (B). Numbers above major branches show bootstrap values from maximum likelihood and distance analyses, respectively. The DN17 tree is rooted at the two distinct sequence copies (groups) in oomycetes. Genes from Bd, oomycetes and bacteria are indicated in different colors. P = Phytophthora; A = Aphanomyces.
