Plant defense against herbivory: progress in identifying
synergism, redundancy, and antagonism between resistance
traits
Sergio Rasmann and Anurag A Agrawal
Plants respond to herbivore attack through a complex and
variable system of defense, involving different physical barriers,
toxic chemicals, and recruitment of natural enemies. To fully
understand the relative role of each type of defense, their
synergisms, redundancies, or antagonisms between traits, a
variety of methods of enquiry, commonly used in plant
physiology and ecology, have been employed. By
overexpressing or silencing genes of interest, it is possible to
understand the specific role of a particular defensive molecule
or mode of action. We argue, however, that these types of
experiments alone are not enough to holistically understand the
physiological as well as ecological role of plant defenses. We
thus advocate for the use of a combination of methods,
including genetic modification, quantitative genetics, and
phylogenetically controlled comparative studies.
