Plant Defences Against Herbivore and Insect Attack
The story of Adam and Eve links eating a forbidden fruit with death in the cycle of human existence (Genesis 3:1– 24). Indeed, to avoid poisoning, herbivores and omnivores such as humans must be cautious in choosing which plants and plant parts to eat. A prevailing hypothesis is that the nearly ubiquitous antiherbivore metabolites in plants were selected by coevolution with herbivores. Likewise...

متن کاملHost plant defense signaling in response to a coevolved herbivore combats introduced herbivore attack
Defense-free space resulting from coevolutionarily naïve host plants recently has been implicated as a factor facilitating invasion success of some insect species. Host plants, however, may not be entirely defenseless against novel herbivore threats. Volatile chemical-mediated defense signaling, which allows plants to mount specific, rapid, and intense responses, may play a role in systems expe...
متن کاملIndependent responses to ultraviolet radiation and herbivore attack in broccoli
The plant responses to ultraviolet-B radiation (UV-B) and to insect herbivory are believed to be partially similar. In this study, responses to these factors were investigated in the crop species broccoli (Brassica oleracea L. convar. botrytis, Brassicaceae). Plants were first grown under three UV-B regimes (80%, 23%, and 4% transmittance of ambient UV-B) in greenhouses covered with either inno...
متن کاملSuccessful herbivore attack due to metabolic diversion of a plant chemical defense.
Plants protect themselves against herbivory with a diverse array of repellent or toxic secondary metabolites. However, many herbivorous insects have developed counteradaptations that enable them to feed on chemically defended plants without apparent negative effects. Here, we present evidence that larvae of the specialist insect, Pieris rapae (cabbage white butterfly, Lepidoptera: Pieridae), ar...
