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 ... -
Long term effects of ionising radiation in the Chernobyl Exclusion zone on DNA integrity and chemical defence systems of Scots pine (Pinus sylvestris)
Nybakken, Line; Lee, YeonKyeong; Brede, Dag Anders; Mageroy, Melissa; Lind, Ole Christian; Salbu, Brit; Kashparov, Valerii; Olsen, Jorunn Elisabeth (Peer reviewed; Journal article, 2023-12-15)The Chernobyl Nuclear Power Plant (ChNPP) accident in 1986 resulted in extremely high levels of acute ionising radiation, that killed or damaged Scots pine (Pinus sylvestris) trees in the surrounding areas. Dead trees were ... -
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 ... -
Transcriptomic changes during the establishment of long-term methyl jasmonate-induced resistance in Norway spruce
Wilkinson, Samuel; Dalen, Lars Sandved; Skrautvol, Thomas Olufsen; Ton, Jurriaan; Krokene, Paal; Mageroy, Melissa (Peer reviewed; Journal article, 2022-03-29)Norway spruce (Picea abies) is an economically and ecologically important tree species that grows across northern and central Europe. Treating Norway spruce with jasmonate has long-lasting beneficial effects on tree ...
