dc.description.abstractRhinusa pilosa (Gyllenhaal) (Coleoptera, Curculionidae) induces galls in Linaria vulgaris Mill., Yellow or common toadflax (Plantaginaceae). Gall is defined as atypical plant growth induced by host-specific organisms, and represents larval chamber which provides food and protection during insect development. It has been shown that gall formation is triggered by ovoipositional fluid (cecidogen). In order to determine which cecidogen compounds may have bioactive properties, we performed comparative analysis of phenolics profiles of cecidogen and stem extracts of L. vulgaris using UHPLC coupled with OrbiTrap mass analyzer. In addition, we analyzed the effects of feeding, oviposition and early gall development on Class III peroxidase activity (POD, EC 1.11.1.7) and phenolic content in the stems of L. vulgaris during seven days. Out of 55 phenolic compounds identified in cecidogen and L. vulgaris stem, one unknown phenolic glycoside was found only in cecidogen, which produced an MS2 base peak at 387 m/z, and 327 m/z and 267 m/z base peaks at MS3 and MS4 fragmentation, respectively. Gall development during seven days was accompanied by decreased concentrations of hydroxybenzoic, hydroxycinnamic acids and flavonoids and by slight lignin deposition. An oscillatory induction of POD activity, with the first peak obtained 3 h after oviposition, was related to oxidative burst during stem wounding and oviposition. Overall results suggested the importance of phenolics in stem structural changes and regulation of plant metabolism induced by R. pilosa.sr
