Kjelle avrenningsforsøk. Årsrapport 2022–2023 for jordarbeidingsforsøk på lav erosjonsrisiko
(NIBIO Rapport, Research report, 2024)‘Ingen jordarbeiding om høsten’ har vært et av de viktigste tiltakene mot erosjon og tap av næringsstoffer fra jordbruksarealer siden begynnelsen på 1990-tallet. Avrenningsforsøk som startet på 1980-tallet viser stor effekt ... -
Været i vekstsesongen 2023
(Journal article, 2023)Varierende værforhold og mange rekorder for både temperatur og nedbør har preget været i 2023. Forsommertørke med påfølgende vått vær på ettersommeren ødela mange kornavlinger i sørlige deler av landet, og frukt ble ødelagt ... -
Warmer temperature during asexual reproduction induce methylome, transcriptomic, and lasting phenotypic changes in Fragaria vesca ecotypes
(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 ... -
Methylome, transcriptome, and phenotype changes induced by temperature conditions experienced during sexual reproduction in Fragaria vesca
(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 ... -
Novel insight into lepidopteran phylogenetics from the mitochondrial genome of the apple fruit moth of the family Argyresthiidae
(Peer reviewed; Journal article, 2024-01-02)Background The order Lepidoptera has an abundance of species, including both agriculturally beneficial and detrimental insects. Molecular data has been used to investigate the phylogenetic relationships of major subdivisions ... -
Are fungal epizootics a sign of successful biological control of cereal aphids?
(Peer reviewed; Journal article, 2023-07-26)Pandora neoaphidis is a common entomopathogenic fungus on Sitobion avenae, which is an important aphid pest on cereals in Europe. Pandora neoaphidis is known to cause epizootics (i.e. an unusually high prevalence of infected ... -
Comparative Transcriptome Analysis Reveals Novel Candidate Resistance Genes Involved in Defence against Phytophthora cactorum in Strawberry
(Peer reviewed; Journal article, 2023-06-29)Crown rot, caused by Phytophthora cactorum, is a devastating disease of strawberry. While most commercial octoploid strawberry cultivars (Fragaria × ananassa Duch) are generally susceptible, the diploid species Fragaria ... -
Methyl jasmonate, salicylic acid, and oxalic acid affects growth, inducible defenses, and pine weevil resistance in Norway spruce
(Peer reviewed; Journal article, 2023-07-06)The large pine weevil (Hylobius abietis) is a major regeneration pest in commercial forestry. Pesticide application has historically been the preferred control method, but pesticides are now being phased out in several ... -
Massehåndtering og potetcystenematode
(Journal article, 2023)Potetcystenematode (PCN) er en karanteneskadegjører som utgjør en stor risiko for norsk potetproduksjon, både fordi den vil gjøre stor skade og være svært vanskelig å bekjempe ved etablering. For å beskytte norsk potetproduksjon ... -
Biologisk veiledningsprøving 2022. Ugrasmidler
(NIBIO Rapport, Research report, 2023)I denne rapporten presenteres resultater fra biologisk veiledningsprøving av ugrasmidler; mot ugras i golfgras, mot ugras i vårkorn inkl. testing av VIPS-Ugras, mot fangvekster og ugras i utendørs småskalaforsøk, mot ugras ... -
Genome analysis of Phytophthora cactorum strains associated with crown- and leather-rot in strawberry
(Peer reviewed; Journal article, 2023-07-03)Phytophthora cactorum has two distinct pathotypes that cause crown rot and leather rot in strawberry (Fragaria × ananassa). Strains of the crown rot pathotype can infect both the rhizome (crown) and fruit tissues, while ... -
Fungal succession in decomposing ash leaves colonized by the ash dieback pathogen Hymenoscyphus fraxineus or its harmless relative Hymenoscyphus albidus
(Peer reviewed; Journal article, 2023-04-14)Introduction: The ascomycete Hymenoscyphus fraxineus, originating from Asia, is currently threatening common ash (Fraxinus excelsior) in Europe, massive ascospore production from the saprotrophic phase being a key determinant ... -
Major transcriptomic differences are induced by warmer temperature conditions experienced during asexual and sexual reproduction in Fragaria vesca ecotypes
(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 ... -
Epitype-inducing temperatures drive DNA methylation changes during somatic embryogenesis in the long-lived gymnosperm Norway spruce
(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 ... -
Detection of total fumonisins produced by Fusarium verticillioides (Sacc) isolates from maize kernels in Ethiopia
(Peer reviewed; Journal article, 2023-05-21)Fusarium verticillioides is the most common fungal pathogen of maize in Ethiopia. Many strains of this pathogen produce fumonisin myotoxins that are harmful to human and animal health. This study was conducted to determine ... -
Secondary Metabolites and Their Role in Strawberry Defense
