ATPase-Modulated Stress Granules Contain a Diverse Proteome and Substructure
- Saumya Jain, Joshua R. Wheeler, R. Walters, A. Agrawal, A. Barsic, R. Parker

It is suggested that stress granules contain a stable core structure surrounded by a dynamic shell with assembly, disassembly, and transitions between the core and shell modulated by numerous protein and RNA remodeling complexes. Expand
Phenotypic Plasticity in the Interactions and Evolution of Species
- A. Agrawal
- Biology, Medicine
- 12 October 2001
Phenotypic responses in species interactions represent modifications that can lead to reciprocal change in ecological time, altered community patterns, and expanded evolutionary potential of species. Expand
Biotic interactions and plant invasions.
It is concluded that species introductions generally alter plants' interactions with enemies, mutualists and competitors, and that there is increasing evidence that these altered interactions jointly influence the success of introduced populations. Expand
Plant defense syndromes.
The discovery of convergent plant defense syndromes can be used as a framework to ask questions about how abiotic environments, communities of herbivores, and biogeography are associated with particular defense strategies of plants. Expand
ENEMY RELEASE? AN EXPERIMENT WITH CONGENERIC PLANT PAIRS AND DIVERSE ABOVE- AND BELOWGROUND ENEMIES
It is shown that introduced plants, on average, received less insect herbivory and were subject to half the negative soil microbial feedback compared to natives; attack by fungal and viral pathogens also tended to be reduced on introduced plants compared to native plants. Expand
Transgenerational induction of defences in animals and plants
It is shown that non-lethal exposure of an animal to carnivores, and a plant to a herbivore, not only induces a defence, but causes the attacked organisms to produce offspring that are better defended than offspring from unthreatened parents. Expand
COMMUNITY‐WIDE IMPACTS OF HERBIVORE‐INDUCED PLANT RESPONSES IN MILKWEED (ASCLEPIAS SYRIACA)
Investigation of the seasonal development of the herbivore fauna on common milkweed shows that damage by an early-season stem-feeding weevil reduced growth of monarch larvae and leaf beetle larvae, suggesting that plant quality is reduced by weevil damage. Expand
Specialist versus generalist insect herbivores and plant defense.
Although a novel set of predictions based on current coevolutionary hypotheses are outlined, few consistencies in plant induction by specialists versus generalists, feeding guilds are predictive of differential plant responses. Expand
Additive and interactive effects of plant genotypic diversity on arthropod communities and plant fitness.
Genetic diversity and species diversity can have similar qualitative and quantitative effects on arthropod communities, and the benefit of preserving genetic variation to conserve species diversity and interactions within multitrophic communities is illustrated. Expand
Re-evaluating the costs and limits of adaptive phenotypic plasticity
- J. R. Auld, A. Agrawal, R. Relyea
- Biology, Medicine
- Proceedings of the Royal Society B: Biological…
- 22 February 2010
Conclusions from studies that measure the costs of plasticity have been equivocal, but it is cautioned that these conclusions may be premature owing to a potentially common correlation between environment-specific trait values and the magnitude of trait plasticities that results in imprecise and/or biased estimates of the costs.
