DELLA proteins modulate Arabidopsis defences induced in response to caterpillar herbivory
Upon insect herbivory, many plant species change the direction of metabolic flux from growth into defence. Two key pathways modulating these processes are the gibberellin (GA)/DELLA pathway and the jasmonate pathway. In this study, the effect of caterpillar herbivory on plant-induced responses was compared between wild-type Arabidopsis thaliana (L.) Heynh. and quad-della mutants that have const...

متن کاملAnti- herbivore defences and insect herbivory: Interactive effects of drought and tree neighbours
Handling Editor: Matthew Heard Abstract 1. How much a plant is attacked by insect herbivores likely depends on its apparency and ability to produce defensive traits, which may be modified by neighbouring plants and abiotic conditions. Yet, how much the direct and trait-mediated effects of neighbours on herbivory is modified by abiotic factors is still unknown. 2. By using a tree diversity exper...
متن کاملMechanical defenses of plant extrafloral nectaries against herbivory
Extrafloral nectaries play an important role in plant defense against herbivores by providing nectar rewards that attract ants and other carnivorous insects. However, extrafloral nectaries can themselves be targets of herbivory, in addition to being exploited by nectar-robbing insects that do not provide defensive services. We recently found that the extrafloral nectaries of Vicia faba plants, ...
متن کاملElevational gradients in plant defences and insect herbivory: recent advances in the field and prospects for future research
Classic research on elevational gradients in plant–herbivore interactions holds that insect herbivore pressure is stronger under warmer, less seasonal climates characteristic of low elevations, and that this in turn selects for increased defence in low(relative to high-) elevation plants. However, recent work has questioned this paradigm, arguing that it overly simplifies the ecological complex...
