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 ... -
Interactive effects of light quality during day extension and temperature on bud set, bud burst and paftl2, pacol1-2 and pasoc1 expression in norway spruce (Picea abies (l.) karst.)
Chiang, Camilo; Viejo, Marcos; Aas, Oda Toresdatter; Hobrak, Katharina T.; Strømme, Christian Bianchi; Fløistad, Inger; Olsen, Jorunn Elisabeth (Peer reviewed; Journal article, 2021-03-13)Light and temperature are crucial factors for the annual growth rhythm of tree seedlings of the boreal and temperate zone. Dormant, vegetative winter buds are formed under short days (SD) and altered light quality. In the ... -
Major transcriptomic differences are induced by warmer temperature conditions experienced during asexual and sexual reproduction in Fragaria vesca ecotypes
Zhang, Yupeng; Viejo, Marcos; Yakovlev, Igor; Tengs, Torstein; Krokene, Paal; Hytönen, Timo; Grini, Paul; Fossdal, Carl Gunnar (Peer reviewed; Journal article, 2023-07-14)A major challenge for plants in a rapidly changing climate is to adapt to rising temperatures. Some plants adapt to temperature conditions by generating an epigenetic memory that can be transmitted both meiotically and ... -
Mass spectrometry reveals the presence of specific set of epigenetic DNA modifications in the Norway spruce genome
Yakovlev, Igor; Gackowski, Daniel; Abakir, Abdulkadir; Viejo, Marcos; Ruzov, Alexey; Olinski, Ryszard; Starczak, Marta; Fossdal, Carl Gunnar; Krutovsky, Konstantin V. (Journal article; Peer reviewed, 2019-12-17)5-Methylcytosine (5mC) is an epigenetic modification involved in regulation of gene expression in metazoans and plants. Iron-(II)/α-ketoglutarate-dependent dioxygenases can oxidize 5mC to 5-hydroxymethylcytosine (5hmC), ... -
The epigenetic memory of temperature during embryogenesis modifies the expression of bud burst-related genes in Norway spruce epitypes
Carneros, Elena; Yakovlev, Igor; Viejo, Marcos; Olsen, Jorunn Elisabeth; Fossdal, Carl Gunnar (Journal article; Peer reviewed, 2017)Main conclusion Epigenetic memory affects the timing of bud burst phenology and the expression of bud burstrelated genes in genetically identical Norway spruce epitypes in a manner usually associated with ecotypes. In ...
