Assignment to 4 genetic groups with STRUCTURE and distribution map of genetic groups. (a) Vertical bars represent one R. irregularis isolate of and colours represent the assignment to different genetic groups (K). The delta K value for K=4 was slightly higher than for K=2. (b) Colour coding corresponds to results obtained with STRUCTURE, based on data set 3. Several isolates are of unknown geographical origin and are not presented here. The name of each isolate is written near its respective pie chart, except for the 29 Swiss isolates that are represented as the Swiss population.
