“…This process can be modulated by an appropriate product formulation that ensures droplet retention on the leaf surface and AI partitioning into cuticular waxes, and that enhances diffusion across the lipid layer . However, the subsequent distribution within cells and tissues is usually determined solely by the physicochemical properties of compounds and has been less well studied, even though this distribution has high impact on the effect of a compound on specific pests because of the differences in feeding behaviour . Targeted bioavailability is an important pillar for the responsible use of agrochemicals in modern agriculture and overall product performance in the field.…”

“…Nevertheless, following penetration and rupture of sieve elements by phloem-feeders, defence responses can be induced [8]. Differences in herbivore feeding habits result in variable perception of attack, which can lead to large differences in defence responses [9,10].…”

Plants are subjected to a multitude of stimuli during insect herbivory, resulting in a complex and cumulative defence response. Breaking down the components of herbivory into specific stimuli and identifying the mechanisms of defence associated with them has thus far been challenging. Advances in our understanding of responses to inconspicuous stimuli, such as those induced by microbial symbionts in herbivore secretions and mechanical stimulation caused by insects, have shed light on the intricacies of herbivory. Here we provide a synthesis of the interacting impacts of herbivory on plants and the consequential complexities associated with uncoupling defence responses. We propose that simulated herbivory should be used to complement true herbivory in order decipher the mechanisms of insect herbivoreinduced plant defence responses.

“…Amplas evidências indicam que esta modulação do metabolismo da célula vegetal hospedeira por herbívoros se dá por meio de efetores, de maneira similar a patógenos (BOS et al, 2010;HOGENHOUT, 2012;BALDWIN, 2010).…”

“…Por esta razão, a manipulação de respostas de defesa de plantas hospedeiras por efetores de herbívoros tem sido frequentemente descrita para herbívoros perfuradores-sugadores, os quais afetam as células vegetais pela perfuração com seus estiletes e posterior injeção de saliva. Essa estratégia típica de alimentação permite a liberação de proteínas efetoras pela saliva dentro de células hospedeiras (BOS et al, 2010;HOGENHOUT, 2012 Patógenos biotróficos tipicamente ativam defesas mediadas por SA (DERKSEN et al, 2013), assim como os vírus de RNA (WHITHAM et al, 2003).…”

Gene expression analysis of Arabidopsis thaliana in response to Citrus leprosis virus C and its vector Brevipalpus phoenicisCitrus leprosis, the main viral disease affecting citrus orchards in Brazil, is caused by Citrus leprosis virus C (CiLV-C, genus Cilevirus). CiLV-C has a bipartite genome of singled stranded positive RNA, which encodes six proteins. CiLV-C is plant-to-plant transmitted by Brevipalpus phoenicis mites and can infect more than 40 plant species, invariably producing localized chlorotic or necrotic lesions around the site of feeding of the viruliferous mites. Viral long distance movement in its hosts is not accomplished. To unveil the mechanisms determining the unique characteristic of the virus/mite/plant interaction, activities of main plant defense pathways were evaluated during aviruliferous and CiLV-C viruliferous mite infestation in Arabidopsis thaliana. The expression of 19 marker genes involved in defense responses along a time course experiment (6, 12 and 24 hours after infestation, and after appearance of leprosis symptoms) was assessed by RT-qPCR. Analyses showed that genes involved in the salicylic acid (SA) pathway were up-regulated during plant interaction with mite and virus. The SA pathway expression profile observed at the infestation by viruliferous mites resembled those observed for the aviruliferous mites, but plant response to both stimuli was stronger. Both the jasmonic acid and ethylene pathways were activated during mite/plant interaction and were repressed at the course of infection with CiLV-C, suggesting an antagonistic effect mediated by the activated SA pathway. Gene silencing mechanism was differentially regulated in response to both aviruliferous and viruliferous mites. Upon viral infection, plants responded with the activation of an AGO1-mediated first defense line, in early times of infection; and then switched to an AGO2-mediated defense. Results indicate the activation of a multifactorial process in response to CiLV-C and B. phoenicis mites in A. thaliana.
