Epigenetisk hukommelse og klimatilpasning
Fossdal, Carl Gunnar; Yakovlev, Igor (Glimt fra Skog og landskap;01/11, Others, 2011)Hvor raskt en organisme kan tilpasse seg forandringer, er avgjørende for hvilket utfall raske endring er i klima vil ha for organismens utbred else og overlevelse. Grana viser en evne til utrolig raskt å tilpasse seg ... -
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 ... -
Identification and in silico characterization of novel and conserved microRNAs in methyl jasmonate-stimulated Scots Pine (Pinus sylvestris L.) needles
Krivmane, Baiba; Šņepste, Ilze; Šķipars, Vilnis; Yakovlev, Igor; Fossdal, Carl Gunnar; Vivian-Smith, Adam; Ruņģis, Dainis (Peer reviewed; Journal article, 2020-03-28)MicroRNAs (miRNAs) are non-protein coding RNAs of ~20–24 nucleotides in length that play an important role in many biological and metabolic processes, including the regulation of gene expression, plant growth and developmental ... -
In Silico Analysis of Small RNAs Suggest Roles for Novel and Conserved miRNAs in the Formation of Epigenetic Memory in Somatic Embryos of Norway Spruce
Yakovlev, Igor; Fossdal, Carl Gunnar (Journal article; Peer reviewed, 2017-09-08)Epigenetic memory in Norway spruce affects the timing of bud burst and bud set, vitally important adaptive traits for this long-lived forest species. Epigenetic memory is established in response to the temperature conditions ... -
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), ... -
Methylome, transcriptome, and phenotype changes induced by temperature conditions experienced during sexual reproduction in Fragaria vesca
Zhang, Yupeng; Toivainen, Tuomas; Mackenzie, Kathryn; Yakovlev, Igor; Krokene, Paal; Hytönen, Timo; Grini, Paul; Fossdal, Carl Gunnar (Peer reviewed; Journal article, 2023-06-21)Temperature conditions experienced during embryogenesis and seed development may induce epigenetic changes that increase phenotypic variation in plants. Here we investigate if embryogenesis and seed development at two ... -
Plant-made vaccines against viral diseases in humans and farm animals
Su, Hang; van Erde, André; Rimstad, Espen; Bock, Ralph; Branza-Nichita, Norica; Yakovlev, Igor; Liu Clarke, Jihong (Peer reviewed; Journal article, 2023-03-28)Plants provide not only food and feed, but also herbal medicines and various raw materials for industry. Moreover, plants can be green factories producing high value bioproducts such as biopharmaceuticals and vaccines. ... -
Plant-produced Vaccines: Future Applications in Aquaculture
Su, Hang; Yakovlev, Igor; Eerde, André van; Su, Jianguo; Clarke, Jihong Liu (Peer reviewed; Journal article, 2021-08-12)Aquaculture has undergone rapid development in the past decades. It provides a large part of high-quality protein food for humans, and thus, a sustainable aquaculture industry is of great importance for the worldwide food ... -
Skadesopp til nytte og besvær
Fossdal, Carl Gunnar; Solheim, Halvor; Hietala, Ari Mikko; Yakovlev, Igor (Glimt fra Skog og landskap;05/10, Others, 2010)Rotkjuke, Heterobasidion annosum s.l. er et stort problem i de nordlige barskogsområder. I Norge er hele 20 prosent av grantrærne angrepet av denne skadesoppen. Dette fører ikke bare til at tømmeret blir ubrukelig til de ... -
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 ... -
Transcriptome profiling and in silico detection of the antimicrobial peptides of red king crab Paralithodes camtschaticus
Yakovlev, Igor; Lysøe, Erik; Heldal, Inger; Steen, Hege; Hagen, Snorre; Clarke, Jihong Liu (Peer reviewed; Journal article, 2020-07-29)Endogenous antimicrobial peptides (AMPs) are evolutionarily ancient factors of innate immunity, which are produced by all multicellular organisms and play a key role in their protection against infection. Red king crab ... -
Warmer temperature during asexual reproduction induce methylome, transcriptomic, and lasting phenotypic changes in Fragaria vesca ecotypes
Zhang, Yupeng; Fan, Guangxun; Toivainen, Tuomas; Tengs, Torstein; Yakovlev, Igor; Krokene, Paal; Hytönen, Timo; Fossdal, Carl Gunnar; Grini, Paul (Peer reviewed; Journal article, 2023-07-31)Plants must adapt with increasing speed to global warming to maintain their fitness. One rapid adaptation mechanism is epigenetic memory, which may provide organisms sufficient time to adapt to climate change. We studied ...
