In this review we highlight how the presence of other pathogen species, or other pathogen genotypes, within a plant can affect key components of host-pathogen interactions: (i) within-plant virulence and pathogen accumulation, through direct and host-mediated mechanisms; (ii) evolutionary trajectories of pathogen populations, through virulence evolution, generation of novel genetic combinations, and maintenance of genetic diversity; and (iii) disease dynamics, with multiple infection likely to render epidemics more devastating. The major future challenges are to couple a community ecology approach with a molecular investigation of the mechanisms operating under coinfection and to evaluate the evolution and effectiveness of resistance within a coinfection framework. specialized 076 21 1 80-90 2016 1360-1385 https://www.documentation.ird.fr/hor/fdi:010066171 10.1016/j.tplants.2015.10.014 1360-1385 [F B010066171] https://www.documentation.ird.fr/hor/fdi:010066171 https://www.documentation.ird.fr/intranet/publi/2016/02/010066171.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-02-26 2017-08-23 fdi:010066171 fre
