Bark Beetle-Associated Blue-Stain Fungi Increase Antioxidant Enzyme Activities and Monoterpene Concentrations in Pinus yunnanensis
Pan, Yue; Zhao, Tao; Krokene, Paal; Yu, Ze-fen; Qiao, Min; Lu, Jun; Chen, Peng; Ye, Hui (Journal article; Peer reviewed, 2018-11-27)Yunnan pine is the most important tree species in SW China in both economical and ecological terms, but it is often killed by pine shoot beetles (Tomicus spp.). Tomicus beetles are secondary pests in temperate regions and ... -
Convergent evolution of semiochemicals across Kingdoms: bark beetles and their fungal symbionts
Zhao, Tao; Ganji, Suresh; Schiebe, Christian; Bohman, Björn; Weinstein, Philip; Krokene, Paal; Borg-Karlson, Anna-Karin; Unelius, C. Rikard (Journal article; Peer reviewed, 2019-02-15)Convergent evolution of semiochemical use in organisms from different Kingdoms is a rarely described phenomenon. Tree-killing bark beetles vector numerous symbiotic blue-stain fungi that help the beetles colonize healthy ... -
Fungal associates of the tree-killing bark beetle, Ips typographus, vary in virulence, ability to degrade conifer phenolics and influence bark beetle tunneling behavior
Zhao, Tao; Kandasamy, Dineshkumar; Krokene, Paal; Chen, Jingyuan; Gershenzon, Jonathan; Hammerbacher, Almuth (Journal article; Peer reviewed, 2018-07-20)The bark beetle Ips typographus carries numerous fungi that could be assisting the beetle in colonizing live Norway spruce (Picea abies) trees. Phenolic defenses in spruce phloem are degraded by the beetle's major tree-killing ... -
Fungal symbionts of the spruce bark beetle synthesize the beetle aggregation pheromone 2-methyl-3-buten-2-ol
Zhao, Tao; Axelsson, Karolin; Krokene, Paal; Borg-Karlson, Anna-Karin (Journal article; Peer reviewed, 2015-08-25)Tree-killing bark beetles depend on aggregation pheromones to mass-attack their host trees and overwhelm their resistance. The beetles are always associated with phytopathogenic ophiostomatoid fungi that probably assist ... -
Molecular underpinnings of methyl jasmonate‐induced resistance in Norway spruce
Magerøy, Melissa; Wilkinson, Samuel W.; Tengs, Torstein; Cross, Hugh; Almvik, Marit; Petriacq, Pierre; Vivian-Smith, Adam; Zhao, Tao; Fossdal, Carl Gunnar; Krokene, Paal (Peer reviewed; Journal article, 2020-04-22)In response to various stimuli, plants acquire resistance against pests and/or pathogens. Such acquired or induced resistance allows plants to rapidly adapt to their environment. Spraying the bark of mature Norway spruce ... -
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 ...
