The capacity to perceive and respond is integral to biological immune systems, but to what extent can plants specifically recognize and respond to insects? Recent findings suggest that plants possess surveillance systems that are able to detect general patterns of cellular damage as well as highly specific herbivore-associated cues. The jasmonate (JA) pathway has emerged as the major signaling cassette that integrates information perceived at the plant–insect interface into broad-spectrum defense responses. Specificity can be achieved via JA-independent processes and spatio-temporal changes of JA-modulating hormones, including ethylene, salicylic acid, abscisic acid, auxin, cytokinins, brassinosteroids and gibberellins. The identification of receptors and ligands and an integrative view of hormone-mediated response systems are crucial to understand specificity in plant immunity to herbivores.

• Growth-defense tradeoffs in plants: a balancing act to optimize fitness. (2014, neutral): “Plant defense hormones such as SA, JA, and ET play important roles in the precise regulation of plant immune responses both locally and systemically to coordinate plant defense against different types of pathogens and in different parts of the plant (Erb et al., 2012; Pieterse et al., 2012; Wastern”
