“…Other species are also known to produce this compound in leaves. For example, leaves of rice produce benzylbenzoate in response to oviposition by the insect whitebacked planthopper (Sogatella furcifera), and it was shown that benzylbenzoate has ovicidal properties (Seino et al, 1996). Our results showing that the tobacco hypersensitive-response cDNA HSR201 encodes BEBT suggest that tobacco leaves may also synthesize benzylbenzoate or a related compound under stress.…”

A cDNA encoding a protein with 456 amino acids whose sequence shows considerable similarity to plant acyltransferases was identified among 750 Clarkia breweri flower expressed sequence tags. The cDNA was expressed in Escherichia coli, and the protein produced was shown to encode the enzyme benzoyl-coenzyme A (CoA):benzyl alcohol benzoyl transferase (BEBT). BEBT catalyzes the formation of benzylbenzoate, a minor constituent of the C. breweri floral aroma, but it also has activity with a number of other alcohols and acyl CoAs. The BEBTgene is expressed in different parts of the flowers with maximal RNA transcript levels in the stigma, and no expression was observed in the leaves under normal conditions. However, BEBT expression was induced in damaged leaves, reaching a maximum 6 h after damage occurred. We also show here that a closely related tobacco (Nicotiana tabacum) gene previously shown to be induced in leaves after being challenged by phytopathogenic bacteria also has BEBT activity, whereas the most similar protein to BEBT in the Arabidopsis proteome does not use benzoyl CoA as a substrate and instead can use acetyl CoA to catalyze the formation of cis-3-hexen-1-yl acetate, a green-leaf volatile.

“…From the plants' perspective, mobilizing defenses upon egg deposition may represent an effective strategy to reduce herbivory, as the resistance mechanisms can be activated before the onset of feeding Hilker and Meiners 2006). Indeed, it has been demonstrated that plants after contacting eggs can grow neoplasms, initiate tissue necrosis (hypersensitive response), or produce ovicidal substances in order to kill eggs or isolate hatching larvae from plant tissue (Blackmeer et al 1994;Seino et al 1996;Balbyshev and Lorenzen 1997;Doss et al 2000;Hilker and Meiners 2002). After oviposition, plants can also release volatiles that are attractive to egg parasitoids (Hilker and Meiners 2002) or change chemicals on the leaf surface that arrest egg parasitoids (Fatouros et al 2005(Fatouros et al , 2007.…”

Plant volatiles function as important signals for herbivores, parasitoids, predators, and neighboring plants. Herbivore attack can dramatically increase plant volatile emissions in many species. However, plants do not only react to herbivore-inflicted damage, but also already start adjusting their metabolism upon egg deposition by insects. Several studies have found evidence that egg deposition itself can induce the release of volatiles, but little is known about the effects of oviposition on the volatiles released in response to subsequent herbivory. To study this we measured the effect of oviposition by Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) moths on constitutive and herbivore-induced volatiles in maize (Zea mays L.). Results demonstrate that egg deposition reduces the constitutive emission of volatiles and suppresses the typical burst of inducible volatiles following mechanical damage and application of caterpillar regurgitant, a treatment that mimics herbivory. We discuss the possible mechanisms responsible for reducing the plant's signaling capacity triggered by S. frugiperda oviposition and how suppression of volatile organic compounds can influence the interaction between the plant, the herbivore, and other organisms in its environment. Future studies should consider oviposition as a potential modulator of plant responses to insect herbivores.

“…In pea (Pisum sativum) pods, growth of undifferentiated cells is triggered upon oviposition by the pea weevil, which results in elevating the egg from the surface, increasing the risk of desiccation, predation, or falling off the pod (Doss et al, 2000). Upon oviposition by the white-backed planthopper, rice (Oryza sativa) plants produce benzyl benzoate, an ovicidal substance that causes high egg mortality (Seino et al, 1996). The development of a necrotic zone at the site of egg deposition was observed in Brassica nigra, resulting in egg dessication and mortality (Shapiro and Devay, 1987).…”

Oviposition by Pierid Butterflies Triggers Defense Responses in Arabidopsis

et al. 2006

Insect eggs represent a threat for the plant as hatching larvae rapidly start with their feeding activity. Using a whole-genome microarray, we studied the expression profile of Arabidopsis (Arabidopsis thaliana) leaves after oviposition by two pierid butterflies. For Pieris brassicae, the deposition of egg batches changed the expression of hundreds of genes over a period of 3 d after oviposition. The transcript signature was similar to that observed during a hypersensitive response or in lesion-mimic mutants, including the induction of defense and stress-related genes and the repression of genes involved in growth and photosynthesis. Deposition of single eggs by Pieris rapae caused a similar although much weaker transcriptional response. Analysis of the jasmonic acid and salicylic acid mutants coi1-1 and sid2-1 indicated that the response to egg deposition is mostly independent of these signaling pathways. Histochemical analyses showed that egg deposition is causing a localized cell death, accompanied by the accumulation of callose, and the production of reactive oxygen species. In addition, activation of the pathogenesis-related1Tb-glucuronidase reporter gene correlated precisely with the site of egg deposition and was also triggered by crude egg extract. This study provides molecular evidence for the detection of egg deposition by Arabidopsis plants and suggests that oviposition causes a localized response with strong similarity to a hypersensitive response.
