“…Signals from herbivore eggs have been well documented to induce plant defense (Hilker and Fatouros ). Such signals have been identified in the eggs of the rice white‐backed planthopper Sogatella furcifera , for example; these signals are lipids and can induce rice plants to produce benzyl benzoate, which in turn kills S. furcifera eggs (Yang et al ). The signals from BPH eggs should be exploited in the future.…”

Jasmonic acid (JA) and related metabolites play a key role in plant defense and growth. JA carboxyl methyltransferase (JMT) may be involved in plant defense and development by methylating JA to methyl jasmonate (MeJA) and thus influencing the concentrations of JA and related metabolites. However, no JMT gene has been well characterized in monocotyledon defense and development at the molecular level. After we cloned a rice JMT gene, OsJMT1, whose encoding protein was localized in the cytosol, we found that the recombinant OsJMT1 protein catalyzed JA to MeJA. OsJMT1 is up-regulated in response to infestation with the brown planthopper (BPH; Nilaparvata lugens). Plants in which OsJMT1 had been overexpressed (oe-JMT plants) showed reduced height and yield. These oe-JMT plants also exhibited increased MeJA levels but reduced levels of herbivore-induced JA and jasmonoyl-isoleucine (JA-Ile). The oe-JMT plants were more attractive to BPH female adults but showed increased resistance to BPH nymphs, probably owing to the different responses of BPH female adults and nymphs to the changes in levels of H2 O2 and MeJA in oe-JMT plants. These results indicate that OsJMT1, by altering levels of JA and related metabolites, plays a role in regulating plant development and herbivore-induced defense responses in rice.

Certain Japonica rice plant varieties (Oryza sativa L.) show resistance to the eggs of the white backed planthopper (Sogatella furcifera Horváth) by the formation of watery lesions and production of benzyl benzoate, an active ovicidal compound. Benzyl benzoate results in high ovicidal activity of S. furcifera eggs and reduces egg hatchability. The production of benzyl benzoate by the rice plants is only induced by an unknown elicitor(s) from the female S. furcifera. Therefore, we tried to isolate and identify these elicitors. An active 80% MeOH extract of S. furcifera was separated on a reverse-phase ODS MPLC, and the elicitor(s) was eluted in 100% MeOH and 100% EtOH fractions. Further separation of the active 100% MeOH fraction using a HPLC led to the isolation of four active compounds. The structures of each compound were determined by using NMR, LC-MS, and GC-MS spectra. The compounds were 1,2-dilinoleoyl-sn-glycero-3-phosphocholine, 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine, 1-palmitoyl-2-oleoyl-X-glycero-3-phosphoethanolamine, and 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine.

“…So far, only few studies on oviposition-induced plant defenses have identified the herbivore-associated elicitor. Bruchins isolated from pea weevils ( Doss et al, 2000 ) and phospholipids isolated from rice planthoppers ( Yang et al, 2013 ) have been shown to induce direct egg-killing plant defenses. Our previous studies demonstrated a role of the anti-aphrodisiac compounds BC and indole (in the butterflies P. brassicae and P. rapae , respectively) in eliciting substrate-borne chemical plant cues retaining Trichogramma wasps onto egg-infested B. oleracea leaves.…”

Role of Large Cabbage White butterfly male-derived compounds in elicitation of direct and indirect egg-killing defenses in the black mustard

To successfully exert defenses against herbivores and pathogens plants need to recognize reliable cues produced by their attackers. Up to now, few elicitors associated with herbivorous insects have been identified. We have previously shown that accessory reproductive gland secretions associated with eggs of Cabbage White butterflies (Pieris spp.) induce chemical changes in Brussels sprouts plants recruiting egg-killing parasitoids. Only secretions of mated female butterflies contain minute amounts of male-derived anti-aphrodisiac compounds that elicit this indirect plant defense. Here, we used the black mustard (Brassica nigra) to investigate how eggs of the Large Cabbage White butterfly (Pieris brassicae) induce, either an egg-killing direct [i.e., hypersensitive response (HR)-like necrosis] or indirect defense (i.e., oviposition-induced plant volatiles attracting Trichogramma egg parasitoids). Plants induced by P. brassicae egg-associated secretions expressed both traits and previous mating enhanced elicitation. Treatment with the anti-aphrodisiac compound of P. brassicae, benzyl cyanide (BC), induced stronger HR when compared to controls. Expression of the salicylic (SA) pathway- and HR-marker PATHOGENESIS-RELATED GENE1 was induced only in plants showing an HR-like necrosis. Trichogramma wasps were attracted to volatiles induced by secretion of mated P. brassicae females but application of BC did not elicit the parasitoid-attracting volatiles. We conclude that egg-associated secretions of Pieris butterflies contain specific elicitors of the different plant defense traits against eggs in Brassica plants. While in Brussels sprouts plants anti-aphrodisiac compounds in Pieris egg-associated secretions were clearly shown to elicit indirect defense, the wild relative B. nigra, recognizes different herbivore cues that mediate the defensive responses. These results add another level of specificity to the mechanisms by which plants recognize their attackers.
