Figure 1From: Tracking costs of virulence in natural populations of the wheat pathogen, Puccinia striiformis f.sp.triticiCompetitive success of vir9 isolates in the climate chamber experiment. Mean (± S.E.) frequencies of vir9 isolates relative to avir9 isolates over the course of 5 pathogen generations in pairwise competition experiments. Two A vir/vir pairs (A, B) were competed on two host cultivars (Thésée, Récital). Each point represents the mean and S.E. calculated over 2 independent replicates.Back to article page
