Repeated loss of the ability of a wild pepper disease resistance gene to function at high temperatures suggests that thermoresistance is a costly trait

open access: yesNew Phytologist, Volume 241, Issue 2, Page 845-860, January 2024.
Summary Specificity in plant–pathogen gene‐for‐gene (GFG) interactions is determined by the recognition of pathogen proteins by the products of plant resistance (R) genes. The evolutionary dynamics of R genes in plant–virus systems is poorly understood.
