Abstract
Plantherbivore relationships are complex interactions encompassing elaborate networks of molecules signals and strategies used to overcome defences developed by each other Herbivores use multiple feeding strategies to obtain nutrients from host plants In turn plants respond by triggering defence mechanisms to inhibit block or modify the metabolism of the pest As part of these defences herbivorechallenged plants emit volatiles to attract natural enemies and warn neighbouring plants of the imminent threat In response herbivores develop a variety of strategies to suppress plantinduced protection Our understanding of the plantherbivore interphase is limited although recent molecular approaches have revealed the participation of a battery of genes proteins and volatile metabolites in attackdefence processes This review describes the intricate and dynamic defence systems governing plantherbivore interactions by examining the diverse strategies plants employ to deny phytophagous arthropods the ability to breach newly developed mechanisms of plant resistance A cornerstone of this understanding is the use of transgenic tools to unravel the complex networks that control these interactionsProject funding by the Ministerio de Economía y Competitividad of Spain AGL201123650 by the Government of Canada through Genome Canada and the Ontario Genomics Institute OGI046 and by Ontario Research Fund Global Leadership in Genomics and Life Sciences GL201035
