Phylogenetic tree of the Beauveria and Metarhizium spp. strains based on multilocus analysis. The tree is drawn to scale, with branch lengths measured by the number of substitutions per site. (a) Phylogenetic tree of Beauveria spp. strains obtained with the neighbor-joining method for bloc, tef, rpb1, and rpb2. (b) Phylogenetic tree of Metharizium spp. strains obtained with the neighbor-joining method for tef, rpb1, rpb2, and btuB. Bootstrap values of 50% are labeled above the appropriate internodes. The type strains are indicated with diamonds, and our strains are indicated with circles. NA, not available.
