Figure 2

Phylogenetic tree showing relationships among recA (A) and pheS (B) gene sequences of species in the Lactobacillus acidophilus group, including Lactobacillus taiwanensis , and species representing different lineages within the genus Lactobacillus. The trees were created using a maximum-likelihood approach and numbers at branch points are bootstrap values (based on 500 samplings expressed in percentages). Only bootstrap values over 75% are shown. Bar indicates sequence divergence. The trees have been arbitrarily rooted. In parenthesis are shown the GenBank accession numbers.
