Cardenolides, induced responses, and interactions between above? and belowground herbivores of milkweed (Asclepias spp.) [PDF]

, 2009
Theory has long predicted allocation patterns for plant defense against herbivory, but only recently have both above? and belowground plant defenses been considered simultaneously.

Differential accumulation of cardenolides from Asclepias curassavica by large milkweed bugs does not correspond to availability in seeds or biological activity on the bug Na+/K+-ATPase

Frontiers in Ecology and Evolution, 2023
Milkweed–herbivore systems are characterized by cardenolide chemical defenses and specialized herbivore adaptations such as physiological target site insensitivity.

Toxicity of Milkweed Leaves and Latex: Chromatographic Quantification Versus Biological Activity of Cardenolides in 16 Asclepias Species [PDF]

, 2019
Cardenolides are classically studied steroidal defenses in chemical ecology and plant-herbivore coevolution. Although milkweed plants (Asclepias spp.) produce up to 200 structurally different cardenolides, all compounds seemingly share the same well ...

Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

eLife, 2020
Phytochemical diversity is thought to result from coevolutionary cycles as specialization in herbivores imposes diversifying selection on plant chemical defenses.

Unraveling the roles of genotype and environment in the expression of plant defense phenotypes

Ecology and Evolution, 2021
Phenotypic variability results from interactions between genotype and environment and is a major driver of ecological and evolutionary interactions. Measuring the relative contributions of genetic variation, the environment, and their interaction to ...

Defense of Milkweed Bugs (Heteroptera: Lygaeinae) against Predatory Lacewing Larvae Depends on Structural Differences of Sequestered Cardenolides

Insects, 2020
Predators and parasitoids regulate insect populations and select defense mechanisms such as the sequestration of plant toxins. Sequestration is common among herbivorous insects, yet how the structural variation of plant toxins affects defenses against ...
