Transcriptional profiling of defense responses to Botrytis cinerea infection in leaves of Fragaria vesca plants soil-drenched with β-aminobutyric acid
Badmi, Raghuram; Tengs, Torstein; Brurberg, May Bente; Elameen, Abdelhameed; Zhang, Yupeng; Haugland, Lisa Karine; Fossdal, Carl Gunnar; Hytönen, Timo; Krokene, Paal; Thorstensen, Tage (Peer reviewed; Journal article, 2022-12-08)Grey mold caused by the necrotrophic fungal pathogen Botrytis cinerea can affect leaves, flowers, and berries of strawberry, causing severe pre- and postharvest damage. The defense elicitor β-aminobutyric acid (BABA) is ... -
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 ... -
Using laser micro-dissection and qRT-PCR to analyze cell type-specific gene expression in Norway spruce phloem
Nagy, Nina Elisabeth; Sikora, Katarzyna; Krokene, Paal; Hietala, Ari; Solheim, Halvor; Fossdal, Carl Gunnar (Journal article; Peer reviewed, 2014)The tangentially oriented polyphenolic parenchyma (PP) and radially organized ray parenchyma in the phloem are central in the defense of conifer stems against insects and pathogens. Laser micro-dissection enables examination ... -
