Activation of defense pathways in Scots pine bark after feeding by Pine Weevil (Hylobius abietis)

ABSTRACT: Coniferous trees use the oleoresin, a mixture of non-volatile non-volatile diterpene acids and a large (20-50%) volatile fraction of mono- and sesquiterpenes, as a defence tool against damaging herbivores and pathogens. Volatilization of monoterpenes increases viscosity of oleoresin and finally leading to polymerization of resin and a formation of protective solid plug. Resin storing conifers form an important source of volatile organic compounds (VOCs) mainly dominated by volatile monoterpenes. In the atmosphere, conifer VOCs react with ozone and OH and nitrous oxide radicals forming secondary organic compounds. This project seeks a better understanding of the genetic control of conifer defences and the role of monoterpenoid compounds under biotic stresses. Two separate samples were ana
