Fitness Advantages of P. roqueforti Carrying Wallaby and CheesyTer, for the Use of the Cheese Substrate and for Outgrowing Competitors

(A) Left: pictures of two P. roqueforti strains, with (LCP06166, top) and without (LCP06040, bottom) Wallaby and CheesyTer on minimal medium and cheese medium. Right: mean growth ± SE (in mm) of P. roqueforti strains with and without Wallaby and CheesyTer on the two media.

(B) Left: pictures of a P. biforme challenger (LCP05529, without Wallaby and CheesyTer) on two different P. roqueforti lawns, on cheese, malt agar, and minimal media (bottom: strain LCP06149 with Wallaby and CheesyTer; top: strain LCP05885 without the genomic islands; the first line is a control, i.e., with no P. roqueforti lawn). Right: mean growth ± SE (in mm) of a P. biforme (top) or a P. camemberti (bottom) challenger on P. roqueforti strain lawns with or without Wallaby and CheesyTer.

(C) Growth asymmetry (mean ± SE in mm of deviations from the middle of the Petri dish) in pairwise confrontations of P. roqueforti strains with (W+C+) or without (W−C−) Wallaby and CheesyTer, on cheese medium, for the three types of possible pairs. The A and B letters correspond to significantly different means according to a Tukey-Kramer test. The picture shows examples of confrontations, at left LCP06271 (W+C+) against LCP06157 (W+C+) and at right LCP00148 (W+C+) against LCP06157 (W−C−).
