“…b-Cyclocitral and b-ionone have been shown to inhibit infestation by herbivore pests (Wei et al, 2011;Nyalala et al, 2013;Cáceres et al, 2016). b-Cyclocitral is known to induce SA signaling in Arabidopsis, and MeJA enhances the emission of b-cyclocitral in rice (Oryza sativa; Tanaka et al, 2014;Lv et al, 2015). Loliolide may have a different mode of action from b-cyclocitral.…”

ORCID ID: 0000-0003-4940-288X (S.S.). Jasmonic acid (JA) plays an important role in the induction of herbivore resistance in many plants. However, JA-independent herbivore resistance has been suggested. An herbivore-resistance-inducing substance was isolated from Tobacco mosaic virusinfected tobacco (Nicotiana tabacum) leaves in which a hypersensitive response (HR) was induced and identified as loliolide, which has been identified as a b-carotene metabolite. When applied to tomato (Solanum lycopersicum) leaves, loliolide decreased the survival rate of the two-spotted spider mite, Tetranychus urticae, egg deposition by the same pest, and the survival rate of larvae of the common cutworm Spodoptera litura without exhibiting toxicity against these herbivores. Endogenous loliolide levels increased not only with an infestation by S. litura larvae, but also with the exogenous application of their oral secretions in tomato. A microarray analysis identified cell-wall-associated defense genes as loliolide-responsive tomato genes, and exogenous JA application did not induce the expression of these genes. Suppressor of zeaxanthin-less (szl), an Arabidopsis (Arabidopsis thaliana) mutant with a point mutation in a key gene of the b-carotene metabolic pathway, exhibited the decreased accumulation of endogenous loliolide and increased susceptibility to infestation by the western flower thrip (Frankliniella occidentalis). A pretreatment with loliolide decreased susceptibility to thrips in the JA-insensitive Arabidopsis mutant coronatine-insensitive1. Exogenous loliolide did not restore reduced electrolyte leakage in szl in response to a HR-inducing bacterial strain. These results suggest that loliolide functions as an endogenous signal that mediates defense responses to herbivores, possibly independently of JA, at least in tomato and Arabidopsis plants.

“…( E , E )‐2,4‐Heptadienal was released from the porridge of all varieties, although only at a low concentration, apart from in Q106. It is the oxidation product of linolenic acid and induces the production of the jasmonic acid involved in defense against pathogens infection . 3‐Octen‐2‐one was reported to be dominant in fresh steamed millet flour and has a rosy/fruity odour.…”

BACKGROUND Quinoa porridge is becoming popular among Asian for its nutritional values; hence, it is important to understand its aroma characteristics. RESULTS Volatile compounds in porridge of 30 quinoa varieties were determined by gas chromatography‐mass spectrometry combined with headspace‐solid phase micro‐extraction. In total, 53 volatile compounds were detected and grouped into 14 alkanals, four alcohols, seven ketones, 10 alkanes, 10 acids and esters, and eight heterocycles. The relative content of alkanes (22.97%), acids and esters (44.33%) was comparatively high, although alkanals (11.75%) may dominate the aroma. Most of the compounds were similar with respect to types and numbers, although they varied in amount, whereas 11 compounds varied significantly among different varieties. The 30 varieties could be divided into eight groups based on the concentrations of volatile compounds, although the same varieties would be divided into four groups if based on the relative odour activity values of twelve variable aroma compounds. CONCLUSION Nine compounds were identified as the main contributors to the quinoa porridge aroma, including hexanal, 1‐octen‐3‐ol, 2‐pentylfuran, nonanal, (E,E)‐2,4‐decadienal and 6,10‐dimethyl‐5,9‐undecadien‐2‐one. Heptanal, benzeneacetaldehyde and decanal may play roles in harmonizing the overall aroma. It is also interesting to note that 6,10,14‐trimethyl‐2‐pentadecanone, with a slightly fatty aroma, showed a high content in all varieties. © 2019 Society of Chemical Industry

“…() suggested that the S. furcifera ‐induced accumulation of momilactone A in rice plants resulted in the suppression of M. oryzae . Previous studies indicate that herbivore‐induced plant volatiles (HIPVs) might play an important role in plant disease resistance (Gomi et al ., ; Tanaka et al ., ). In the current study, rice plants in different treatments were closely planted, thus the herbivory‐induced volatiles might affect rice blast resistance in both insect‐infested and uninfested control plants.…”

Herbivore‐induced rice resistance against rice blast mediated by salicylic acid

et al. 2018

In agro-ecosystems, plants are important mediators of interactions between their associated herbivorous insects and microbes, and any change in plants induced by one species may lead to cascading effects on interactions with other species. Often, such effects are regulated by phytohormones such as jasmonic acid (JA) and salicylic acid (SA). Here, we investigated the tripartite interactions among rice plants, three insect herbivores (Chilo suppressalis, Cnaphalocrocis medinalis or Nilaparvata lugens), and the causal agent of rice blast disease, the fungus Magnaporthe oryzae. We found that pre-infestation of rice by C. suppressalis or N. lugens but not by C. medinalis conferred resistance to M. oryzae. For C. suppressalis and N. lugens, insect infestation without fungal inoculation induced the accumulation of both JA and SA in rice leaves. In contrast, infestation by C. medinalis increased JA levels but reduced SA levels. The exogenous application of SA but not of JA conferred resistance against M. oryzae. These results suggest that pre-infestation by C. suppressalis or N. lugens conferred resistance against M. oryzae by increasing SA accumulation. These findings enhance our understanding of the interactions among rice plant, insects and pathogens, and provide valuable information for developing an ecologically sound strategy for controlling rice blast.
