Evolutionary relationships of E. festucae Fl1 SLPs. Neighbor joining analysis determined phylogenetic relationships. The phylogram is rooted using the Bacillus subtilis subtilisin Carlsberg protein (accession P00780) as an outgroup. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) is shown next to the branches. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. SLP families and subfamilies are indicated by black or grey square brackets respectively.
