TLDR
A detailed understanding of plant immunity to arthropod herbivores will provide new insights into basic mechanisms of chemical communication and plant-animal coevolution and may also facilitate new approaches to crop protection and improvement.Abstract:
Herbivorous insects use diverse feeding strategies to obtain nutrients from their host plants. Rather than acting as passive victims in these interactions, plants respond to herbivory with the production of toxins and defensive proteins that target physiological processes in the insect. Herbivore-challenged plants also emit volatiles that attract insect predators and bolster resistance to future threats. This highly dynamic form of immunity is initiated by the recognition of insect oral secretions and signals from injured plant cells. These initial cues are transmitted within the plant by signal transduction pathways that include calcium ion fluxes, phosphorylation cascades, and, in particular, the jasmonate pathway, which plays a central and conserved role in promoting resistance to a broad spectrum of insects. A detailed understanding of plant immunity to arthropod herbivores will provide new insights into basic mechanisms of chemical communication and plant-animal coevolution and may also facilitate new approaches to crop protection and improvement.read more

Hormonal Modulation of Plant Immunity
Corné M. J. Pieterse,Dieuwertje van der Does,Christos Zamioudis,Antonio Leon-Reyes,Saskia C. M. Van Wees +4 more
TL;DR: Evidence is emerging that beneficial root-inhabiting microbes also hijack the hormone-regulated immune signaling network to establish a prolonged mutualistic association, highlighting the central role of plant hormones in the regulation of plant growth and survival.

Mechanisms of plant defense against insect herbivores

TL;DR: By understanding the mechanisms of induced resistance, this work can predict the herbivores that are likely to be affected by induced responses and could be exploited as an important tool for the pest management to minimize the amounts of insecticides used for pest control.

Herbivory in relation to plant nitrogen content
TL;DR: The evidence that N is scarce and perhaps a limiting nutrient for many herbivores, and that in response to this selection pressure, many Herbivores have evolved specific behavioral, morphological, physiological, and other adaptations to cope with and uti lize the ambient N levels of their normal haunts is examined.
