Oviposition by Spodoptera exigua on Solanum dulcamara Alters the Plant’s Response to Herbivory and Impairs Larval Performance

Abstract: 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… Show more

“…the plant's transcriptional response to eggs, larval feeding and to the combination of eggs followed by larval feeding involves several phytohormone pathways. Our analysis, and the earlier original publications 12,17,21,22,24 to which our analysis refers, found prominent regulation of GS related to phytohormone signalling. Therefore, we compared the enrichment of all GS associated with phytohormone signalling and metabolism that were up-or down-regulated in at least one of the species combinations (Fig.…”

“…affect the feeding-induced changes of JA and SA levels one day after the onset of feeding by conspecific larvae [19][20][21][22] . Prior oviposition on N. attenuata did, however, result in a stronger transcriptional induction of the JA-responsive transcription factor MYB8 after feeding by larvae of the moths Spodoptera exigua or Manduca sexta 19,20 .…”

“…Oviposition by Spodoptera exigua increased Solanum dulcamara resistance to the subsequent feeding larvae using transcriptome and metabolome analyses. The genes involved in phenylpropanoid metabolism signi cantly overexpressed in previously oviposited S. dulcamara plants by lepidopteran herbivore S. exigua [12]. Moreover, pro les of volatile emission did vary in the indirect defenses of Populus nigra to leaf herbivory by lepidopteran species (Lymantria dispar, Laothoe populi and Amata mogadorensis) and beetles species (Phratora vulgatissima and Chrysomela populi) [27].…”

“…DiscussionPlants can reorganize their transcriptome, proteome and metabolome to deal with abiotic and biotic stress [11]. Plant resistance traits are extremely plastic against insect herbivores [12]. However, the protein and metabolite constituents of host plants are determined by the plant species, herbivore species, infested time, and detection techniques [13].…”
