Jasmonate response decay and defense metabolite accumulation contributes to age-regulated dynamics of plant insect resistance
Abstract
Immunity deteriorates with age in animals but less is known about how aging affects immunity in plants. Here, Maoet al. show that responsiveness to the major insect defense hormone JA declines as plants age, but insect resistance still increases as plants accumulate secondary metabolites such as glucosinolates.
