AB  - A survey of genetic diversity of “flavescence dorée” (FD)-related phytoplasmas in grapevines, alders and clematis as well as alder-feeding leafhoppers was conducted in France, Hungary, Germany, Italy and Serbia. Genotyping was based on the housekeeping gene map and on the vmp genes encoding surface variable membrane proteins. Transmission assays of the phytoplasmas were performed with alder and/or grapevine-feeding leafhoppers. The study demonstrated that European alders constitute an original reservoir of FD phytoplasma by hosting a high diversity of FD-related phytoplasma genotypes, also present in non viticultural areas. The alder phytoplasmas grouping in Vmp-I cluster were transmitted by the Macropsinae O. alni, but were not compatible with the FD phytoplasma vector on grapevine the Deltocephalinae Scaphoideus titanus. The alder phytoplasmas in Vmp-II and -III clusters were transmitted by the Deltocephalinae Allygus spp. and Orientus ishidae. Such pre-existing phytoplasmas were compatible with S. titanus transmissibility and can be responsible for the emergence of
FD phytoplasma epidemics in grapevine. VmpA proteins of cluster II better adhered to Euscelidius variegatus and S. titanus
insect cells and midguts than those of cluster I. Such adhesins might play a key role in the adaptation to new vectors

AB  - Rhinusa 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.
