(Submitter supplied) Induced plant responses to insect herbivores are well studied, but we know very little about responses to gastropod feeding. We aim to identify the temporal dynamics of signalling- and defence-related plant responses after slug feeding in relation to induced resistance. We exposed Solanum dulcamara plants to feeding by the grey field slug (GFS; Deroceras reticulatum) for different periods and tested discs of local and systemic leaves in preference assays. more...

(Submitter supplied) Plant resistance traits against insect herbivores are extremely plastic. Plants respond not only to the herbivory itself, but also to oviposition by herbivorous insects. How prior oviposition affects plant responses to larval herbivory is largely unknown. Combining bioassays and defense protein activity assays with microarray analyses and metabolite profiling, we investigated the impact of preceding oviposition on the interaction of Solanum dulcamara with the generalist lepidopteran herbivore Spodoptera exigua at the levels of the plant's resistance, transcriptome and metabolome. more...

(Submitter supplied) In nature, plants are frequently subjected to multiple biotic and abiotic stresses, resulting in a convergence of adaptive responses. We hypothesized that hormonal signalling regulating defences to different herbivores may interact with drought response, causing distinct resistance phenotypes. To test this, we studied hormonal and transcriptomic responses of Solanum dulcamara subjected to drought and herbivory by the generalist Spodoptera exigua (BAW) or the specialist Leptinotarsa decemlineata (CPB). more...

(Submitter supplied) Plants can respond to insect oviposition but little is known about which responses directly target the insect eggs and how. Here, we reveal a mechanism by which the bittersweet nightshade, Solanum dulcamara, kills the eggs of a generalist noctuid herbivore. The plant responded at the site of oviposition by Spodoptera exigua with neoplasm and chlorotic tissue formation, accumulation of reactive oxygen species and induction of defence genes and proteins. more...

(Submitter supplied) Plants are attacked by diverse herbivores and respond with manifold defense responses. To study transcriptional and other early regulation events of these plant responses, herbivory is often mimicked to standardize the temporal and spatial dynamics that vary tremendously for natural herbivory. Yet to what extent such mimics of herbivory are able to elicit the same plant response as real herbivory remains largely undetermined. more...

(Submitter supplied) We use Solanum dulcamara subjected to drought or flooding and damaged by Spodoptera exigua to analyze such interactions at multiple levels. Drought and herbivory caused comparable effects on S. dulcamara physiological response, which was reflected by a considerable overlap in S. dulcamara transcriptomic profiles. This included many defense responses and genes involved in biosynthesis of secondary metabolites that were induced by drought and herbivory but repressed by flooding. more...
