Olfactory perception of herbivore‐induced plant volatiles elicits counter‐defenses in larvae of the tobacco cutworm
<ol> <li>Herbivore attack leads to increased emission of herbivore-induced plant volatiles (HIPVs) that protect plants by eliciting direct anti-herbivore defenses and indirect defenses via attraction of natural enemies. Whether herbivorous insects can develop counter-defenses against host plants in response to HIPVs is largely unexplored.</li> <li>Using a directed airflow apparatus, we investigated the influence of HIPVs emitted from tobacco cutworm (<i>Spodoptera litura</i><span>)</span>-infested tomatoes on larval performance on herbivore-pretreated tomatoes vs. untreated tomatoes or on trypsin inhibitor-amended artificial diets vs. unamended diets, as well as the transcriptional responses of HIPV-exposed larvae.</li> <li> <i>S. litura</i> larval<i> </i>feeding on tomato plants led to increased emission of HIPVs. The HIPV-exposed larvae showed significantly increased survival rates and weight gains on both herbivore-pretreated tomato leaves and trypsin inhibitor-supplemented diet but not on untreated tomato leaves and control diets, nor when they had been exposed to HIPVs emitted from <i>spr8</i> mutant plants which barely emit terpenes. These results suggest that larval exposure to HIPVs from wild-type plants enhanced their ability to cope with plant induced defenses. The latter is supported by the observation that larval exposure to HIPVs led to enhanced transcript levels of eight genes encoding cuticle proteins, and seven genes encoding cytochrome P450s, an important class of detoxification enzymes<i>.</i> </li> <li>Our studies revealed a mechanism by which larval olfactory perception of HIPVs elicits counter-defenses that enhance the ability of insect herbivores to withstand host plant chemical defenses.</li> </ol>
Data from: The role of volatile plant secondary metabolites as pre-ingestive cues and potential toxins dictating diet selection by African elephants
Understanding the factors driving diet selection represents one of the main thrusts of contemporary foraging ecology. Many studies have focussed on nutritional factors and anti-nutritional factors (such as tannins) that may describe diet selection of generalist mammalian herbivores, but these often do not explain the observed feeding patterns. Alternatively, generalist herbivores may be influenced by the presence, diversity, and/or concentration of toxins. Plant volatiles have been understudied, yet may play an important role in this context. We aimed to determine whether diet selection by African elephants is better correlated with the presence and concentration of toxic plant secondary metabolites (PSMs) than with nutritional or anti-nutritional factors. We also aimed to identify the specific aspects of the plant-odour profiles that were correlated with dietary selection, which could be used as a pre-ingestive cue for food selection. We found that elephant diet selection was not well described by crude protein, in vitro digestibility, tannin concentration, and total polyphenol concentration. Instead, the best predictors of elephant diet choice were the number and absolute (total) emissions of potentially toxic volatile PSMs, specifically monoterpenes. Elephants avoided plant species that emitted a wider diversity of volatile PSMs, had higher total emissions, and higher numbers and emissions of monoterpenes. This suggests that PSMs with a high propensity to become toxins, such as monoterpenes, are likely a better indicator for elephant diet avoidance than nutritional or anti-nutritional factors. Moreover, we demonstrated that elephants can differentiate between food items based on odour alone, specifically volatile monoterpenes, suggesting that these animals are relying on specific volatile cues emitted from plants to direct their foraging choices prior to ingesting selected plants.
Data from: Compatible and incompatible pathogen-plant interactions differentially affect plant volatile emissions and the attraction of parasitoid wasps
The effects of multiple insect attacks on herbivore-induced plant volatiles and carnivorous arthropods are increasingly studied. Phytopathogens also represent an important threat to plants, and plant defense strategies against pathogens and insects are strongly interconnected, yet the potential impact of pathogens on insect-induced volatiles has been largely overlooked, and degree of pathogenicity rarely considered. We investigated how pathogen challenge, with virulent and avirulent strains of Xanthomonas campestris either alone or with simultaneous Pieris brassicae caterpillar herbivory, affected the volatile emissions of Brassica nigra plants. The impact of these volatiles on the foraging behavior of Cotesia glomerata parasitoids was then assessed. Pathogens themselves induced volatiles that were highly attractive to parasitoids, and enhanced the attractiveness of host-infested plant volatiles. Chemical analyses revealed that virulent and avirulent strains differentially induced plant volatiles, with primarily sesquiterpene, homoterpene and green leaf volatile compounds contributing to the differences. Strong similarities were found in the blends induced by the virulent strain and caterpillar herbivory. Challenge by either virulent or avirulent pathogens has a significant impact on plant chemistry and its interactions with other community members, demonstrating the importance of integrating pathogen- and insect-based research to broaden our knowledge of plant defenses under conditions of increasing complexity.
Data from: Integration of two herbivore-induced plant volatiles results in synergistic effects on plant defense and resistance
Plants can use induced volatiles to detect herbivore‐ and pathogen‐attacked neighbors and prime their defenses. Several individual volatile priming cues have been identified, but whether plants are able to integrate multiple cues from stress‐related volatile blends remains poorly understood. Here, we investigated how maize plants respond to two herbivore‐induced volatile priming cues with complementary information content, the green leaf volatile (Z)‐3‐hexenyl acetate (HAC) and the aromatic volatile indole. In the absence of herbivory, HAC directly induced defense gene expression, while indole had no effect. Upon induction by simulated herbivory, both volatiles increased jasmonate signaling, defense gene expression and defensive secondary metabolite production and increased plant resistance. Defenses and resistance in dual‐volatile exposed plants were more strongly induced than in plants exposed to single volatiles. Induced defense levels in dual volatile‐exposed plants were significantly higher than predicted from the added effects of the individual volatiles, with the exception of induced plant volatile production, which showed no increase upon dual‐exposure relative to single exposure. Thus, plants can integrate different volatile cues into strong and specific responses that promote herbivore defense induction and resistance. Integrating multiple volatiles may be beneficial, as volatile blends are more reliable indicators of future stress than single cues.
