• Hydroxyacetophenone defenses in white spruce against spruce budworm 

      Parent, Geneviève J.; Méndez-Espinoza, Claudia; Giguère, Isabelle; Mageroy, Melissa; Charest, Martin; Bauce, Éric; Bohlmann, Joerg; MacKay, John J. (Peer reviewed; Journal article, 2019-10-23)
      We review a recently discovered white spruce (Picea glauca) chemical defense against spruce budworm (Choristoneura fumiferana) involving hydroxyacetophenones. These defense metabolites detected in the foliage accumulate ...
    • In vivo function of Pgβglu-1 in the release of acetophenones in white spruce 

      Mageroy, Melissa; Lachance, Denis; Jancsik, Sharon; Parent, Genevieve; Seguin, Armand; Mackay, John; Bohlmann, Joerg (Journal article; Peer reviewed, 2017-07-07)
      Eastern spruce budworm (Choristoneura fumiferiana Clemens) (ESBW) is a major forest pest which feeds on young shoots of white spruce (Picea glauca) and can cause landscape level economic and ecological losses. Release of ...
    • Priming of inducible defenses protects Norway spruce against tree-killing bark beetles 

      Mageroy, Melissa; Christiansen, Erik; Långström, Bo; Borg-Karlson, Anna-Karin; Solheim, Halvor; Björklund, Niklas; Zhao, Tao; Schmidt, Axel; Fossdal, Carl Gunnar; Krokene, Paal (Peer reviewed; Journal article, 2019-11-01)
      Plants can form an immunological memory known as defense priming, whereby exposure to a priming stimulus enables quicker or stronger response to subsequent attack by pests and pathogens. Such priming of inducible defenses ...
    • Surviving in a Hostile World: Plant Strategies to Resist Pests and Diseases 

      Wilkinson, Samuel; Mageroy, Melissa; Sánchez, Ana López; Smith, Lisa M.; Furci, Leonardo; Cotton, T. E. Anne; Krokene, Paal; Ton, Jurriaan (Journal article; Peer reviewed, 2019-08)
      As primary producers, plants are under constant pressure to defend themselves against potentially deadly pathogens and herbivores. In this review, we describe short- and long-term strategies that enable plants to cope with ...
