Fig. 3From: Population structure of Venturia inaequalis, a causal agent of apple scab, in response to heterogeneous apple tree cultivationAncestral proportion of Venturia inaequalis haplotypes from the Kâ=â2 to Kâ=â5 clusters inferred with STRUCTUREÂ 2.3.4 and TESS 2.3.1 software on the left and right, respectively. In total, 606 strains are grouped according to the origin and cultivar of their host plant. Each vertical bar representing an individual is partitioned into K clusters. The dominant colour for each population indicates its affiliation to the inferred clusterBack to article page
