However, the cellular implications of ionizing radiation (IR) delivered per time unit (dose ... -
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)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 ... -
