Coalescent-based gene genealogies with the highest root probability [L = 1.3438e-53, SD = 1.3225e-53 for A) pP42F, and L = 2.5718e-96, SD = 1.8275e-96 for B) pP89 locus] showing the distribution of mutations in the two major clades of Rhizoctonia solani AG-3 (the AG-3 PT from potato ad AG-3 TB from tobacco). Mutations and bifurcations are time ordered from the top (past) to the bottom (present). The mutations designations are correspondent to respective site numbers described in the additional files 1 and 2. The inferred gene genealogies are based on 100,000 simulations of the coalescent with Waterston's estimates of Θ (M) = 2.57 for pP42F and 2.27 for pP89. The time scale is expressed in coalescent units of 4N (where N is the populations size). The letters below the tree designate the distinct haplotypes, their total or geographically distinct observed frequencies. Based on estimates of gene flow between the Northern US and Eastern NC populations from AG-3 PT (Table 2), the coalescent was inferred pooling the two populations of the pathogen for the pP42F locus.
