    • Epitype-inducing temperatures drive DNA methylation changes during somatic embryogenesis in the long-lived gymnosperm Norway spruce 

      Viejo, Marcos; Tengs, Torstein; Yakovlev, Igor; Cross, Hugh; Krokene, Paal; Olsen, Jorunn Elisabeth; Fossdal, Carl Gunnar (Peer reviewed; Journal article, 2023-07-20)
      An epigenetic memory of the temperature sum experienced during embryogenesis is part of the climatic adaptation strategy of the long-lived gymnosperm Norway spruce. This memory has a lasting effect on the timing of bud ...

    • Fungal diversity and seasonal succession in ash leaves infected by the invasive ascomycete Hymenoscyphus fraxineus 

      Cross, Hugh; Sønstebø, Jørn Henrik; Nagy, Nina Elisabeth; Timmermann, Volkmar; Solheim, Halvor; Børja, Isabella; Kauserud, Håvard; Carlsen, Tor; Rzepka, Barbara; Wasak, Katarzyna; Vivian-Smith, Adam; Hietala, Ari Mikko (Journal article; Peer reviewed, 2017-01-12)
      High biodiversity is regarded as a barrier against biological invasions. We hypothesized that the invasion success of the pathogenic ascomycete Hymenoscyphus fraxineus threatening common ash in Europe relates to differences ...

    • 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 ...
