From: Comparative secretome analysis suggests low plant cell wall degrading capacity in Frankia symbionts
Phylogenetic trees of secreted hydrolytic enzyme genes. Various patterns of gene retention and acquisition are observed in Frankia hydrolase genes, including (A) conservation of an ancestral gene; (B) gene loss in one strain; (C) horizontal acquisition; (D) and (E) gene family expansion (see text). Trees were generated using PhyML (maximum likelihood method). *not predicted to contain a signal peptide by SignalP or TATFIND 1.4.
