Population pairwise Φ_ST ^a of Rhizoctonia solani AG-3 PT and TB collected from commercial potato or tobacco fields in Northern US, Eastern and Central North Carolina and Southern Brazil for loci pP42F (above diagonal) and pP89 (below diagonal)

^a Population pairwise Φ_ST was calculated using ARLEQUIN version 2.000 [64]. Asterisks indicate significance of P values at P ≤ 0.05 (*) leading to values of Φ_ST larger than or equal to the observed value when permuting molecular sequencing genotypes between populations (1000 permutations were performed).
