The evolving threat of new pathogen variants in the face global environmental changes poses a risk to sustainable crop production. Predicting and responding how climate change affects plant-pathosystems is challenging, as environment host-pathogen interactions from molecular community level, with eco-evolutionary feedbacks at play. To address this knowledge gap, we studied short-term within-host pathogen, Xanthomonas perforans, on resistant susceptible pepper open-top chambers (OTCs) under elevated Ozone (O3) conditions single growing season. We observed increased disease severity greater variance cultivar O3, yet no apparent cultivar. Despite dominance genotype cultivar, supported heterogeneous population. Altered O3 levels led strain turnover, relatively gene flux Both standing genetic variation de novo parallel mutations contributed toward evolutionary modifications during adaptation onto presence however, higher polymorphism, random transient mutations. Population heterogeneity along variation, promotion interdependency are mechanisms by which responds stressors. While may provide clues predicting long-term evolution adaptive potential. And, high proportion suggest less predictable climatic alterations. This relevant study emergence constraints underlying shifts.
