Cardenolides, induced responses, and interactions between above- and belowground herbivores of milkweed (Asclepias spp.).
Theory has long predicted allocation patterns for plant defense against herbivory, but only recently have both above- and belowground plant defenses been considered simultaneously. Milkweeds in the genus Asclepias are a classic chemically defended clade of plants with toxic cardenolides (cardiac glycosides) and pressurized latex employed as anti-herbivore weapons. Here we combine a comparative ...
متن کاملGenetic Variation of the Host Plant Species Matters for Interactions with Above- and Belowground Herbivores
Plants are challenged by both above- and belowground herbivores which may indirectly interact with each other via herbivore-induced changes in plant traits; however, little is known about how genetic variation of the host plant shapes such interactions. We used two genotypes (M4 and E9) of Solanum dulcamara (Solanaceae) with or without previous experience of aboveground herbivory by Spodoptera ...
متن کاملCrosstalk between above- and belowground herbivores is mediated by minute metabolic responses of the host Arabidopsis thaliana
Plants are frequently under attack by multiple herbivores and can be infested at their shoots as well as their roots. As a consequence, plant metabolites are readily induced, mediated by phytohormones such as salicylic acid and jasmonic acid. Thereby, cross-talk between signal transduction pathways may occur if different herbivores attack the plant simultaneously. In turn, modifications in the ...
متن کاملGlobal climate change and above- belowground insect herbivore interactions
Predicted changes to the Earth's climate are likely to affect above-belowground interactions. Our understanding is limited, however, by past focus on two-species aboveground interactions mostly ignoring belowground influences. Despite their importance to ecosystem processes, there remains a dearth of empirical evidence showing how climate change will affect above-belowground interactions. The r...
متن کاملCoexisting congeners: demography, competition, and interactions with cardenolides for two milkweed-feeding aphids
Explaining the coexistence of closely related species sharing a single resource has been a long-standing challenge in ecology. Here we report on studies comparing the aphids Aphis nerii and A. asclepiadis that feed sympatrically on the milkweed Asclepias syriaca in northeastern North America. We sought to identify tradeoffs among species’ attributes that might promote coexistence, but in most i...
