Resistance gene-dependent plant defense responses.

Plants are constantly being challenged by aspiring pathogens, but disease is rare. Why? Broadly, there are three reasons for pathogen failure. Either (1) the plant is unable to support the niche requirements of a potential pathogen and is thus a nonhost; or (2) the plant possesses preformed structural barriers or toxic compounds that confine successful infections to specialized pathogen species...

Male-derived butterfly anti-aphrodisiac mediates induced indirect plant defense.

Plants can recruit parasitic wasps in response to egg deposition by herbivorous insects-a sophisticated indirect plant defense mechanism. Oviposition by the Large Cabbage White butterfly Pieris brassicae on Brussels sprout plants induces phytochemical changes that arrest the egg parasitoid Trichogramma brassicae. Here, we report the identification of an elicitor of such an oviposition-induced p...

Induced Plant Defense: Evolution of Induction and Adaptive Phenotypic Plasticity

Induced defenses may evolve in natural plant populations where heritable variation in inducibility affects plant fitness. Although this has not been documented for any plant – parasite system, genetic variation in induction has been recently reported for several plant-parasite systems. Correlations between induction and fitness in variable parasite environments suggest that inducibility may ind...

Defoliating insect immune defense interacts with induced plant defense during a population outbreak.

During population outbreaks, top-down and bottom-up factors are unable to control defoliator numbers. To our knowledge, details of biotic interactions leading to increased population density have not been studied during real population outbreaks. We experimentally assessed the strength of plant defenses and of insect immunocompetence, assumed to contribute to active insect resistance against pa...
