Quantitative plant resistance enhances pathogen adaptation to ecological stresses

Host-pathogen interactions play an important role in shaping ecosystems with many fundamental and applied implications. However, many aspects of the processes, consequences and mechanisms of these antagonistic interactions are still unknown. Evolutionary theory hypothesizes that quantitative plant resistance (QPR) enhances pathogen pathogenicity, therefore, threatening ecological function and sustainability but this hypothesis has rarely been tested empirically. Here, we present results from an eco-evolutionary study of a quantitative plant-pathogen interaction using 16 potato varieties and >2000 Phytophthora infestans strains. Twelve functional traits in a subset (>300 strains) of the P. infestans populations derived from these varieties were compared. Our results indicate that QPR enhances pathogen pathogenicity and facilitates pathogen adaptation to other disease management attempts including the deployment of qualitative plant resistance and the application of fungicides, and ..., , , # Quantitative plant resistance enhances pathogen adaptation to ecological stresses [https://doi.org/10.5061/dryad.573n5tbh7](https://doi.org/10.5061/dryad.573n5tbh7) ## Description of the data and file structure Raw data belonging to: Li-Na Yang†, Zhe-Chao Pan†, Oswald Nkurikiyimfura†, Jianjun Lu, Yan-Ping Wang, Ying Wang, Abdul Waheed, Han-Mei Fang, Peter H.
