Variation and fitness costs for tolerance to different types of herbivore damage in Boechera stricta genotypes with contrasting glucosinolate structures.

ABSTRACT: • Analyses of plant tolerance in response to different modes of herbivory are essential to an understanding of plant defense evolution, yet are still scarce. Allocation costs and trade-offs between tolerance and plant chemical defenses may influence genetic variation for tolerance. However, variation in defenses also occurs for the presence or absence of discrete chemical structures; yet, the effects of intraspecific polymorphisms on tolerance to multiple herbivores have not been evaluated. • Here, in a glasshouse experiment, we investigated the variation for tolerance to different types of herbivore damage, and direct allocation costs, in 10 genotypes of Boechera stricta (Brassicaceae), a wild relative of Arabidopsis, with contrasting foliar glucosinolate chemical structures (methionine-d
