Different Resistance to DON versus HT2 + T2 Producers in Nordic Oat Varieties
Hofgaard, Ingerd Skow; Brodal, Guro; Almvik, Marit; Lillemo, Morten; Russenes, Aina Lundon; Edwards, Simon Graham; Aamot, Heidi Udnes (Peer reviewed; Journal article, 2022)Over recent decades, the Norwegian cereal industry has had major practical and financial challenges associated with the occurrence of Fusarium head blight (FHB) pathogens and their associated mycotoxins in cereal grains. ... -
Effect of microoganisms on gluten quality in wheat
Nielsen, Katherine Ann Gredvig (Master thesis, 2017)Food security is a current issue of both domestic and international concern. Faced with a growing population and the increased food demands it entails, the Norwegian government has recently renewed its commitment to increase ... -
Environmental factors associated with glutenin polymer assembly during grain maturation
Koga, Shiori; Aamot, Heidi Udnes; Uhlen, Anne Kjersti; Seehusen, Till; Veiseth-Kent, Eva; Hofgaard, Ingerd Skow; Moldestad, Anette; Böcker, Ulrike (Journal article; Peer reviewed, 2020)This study aims to understand the environmental factors, focusing on rain and fungal infection, affecting the assembly of glutenin polymers during grain maturation. Spring wheat was grown in the field and grains were sampled ... -
Fusarium langsethiae and mycotoxin contamination in oat grain differed with growth stage at inoculation
Aamot, Heidi Udnes; Mousavi, Hesam; Razzaghian, Jafar; Brodal, Guro; Sulyok, Michael; Krska, Rudolf; Edwards, Simon G.; Hofgaard, Ingerd Skow (Peer reviewed; Journal article, 2022)High levels of mycotoxins are occasionally observed in Norwegian oat grain lots. Mycotoxins of primary concern in Norwegian oats are deoxynivalenol (DON) produced by Fusarium graminearum and HT2- and T2-toxins (HT2 + T2) ... -
Fusarium poae and Fusarium langsethiae in an oat field-time point of infection and possible inoculum sources
Rassat, Alexandra Roos (Master thesis, 2019)Fusarium head blight in cereals is a global issue, threatening food production and food security. Most Fusarium head blight organisms are able to produce a wide range of mycotoxins, posing human- and animal health risks ... -
Global transcriptome changes in perennial ryegrass during early infection by pink snow mould
Kovi, Mallikarjuna Rao; Abdelhalim, Mohamed; Kunapareddy, Anil; Ergon, Åshild; Tronsmo, Anne Marte; Brurberg, May Bente; Hofgaard, Ingerd Skow; Asp, Torben; Rognli, Odd Arne (Journal article; Peer reviewed, 2016)Lack of resistance to pink snow mould (Microdochium nivale) is a major constraint for adaptation of perennial ryegrass (Lolium perenne L.) to continental regions with long-lasting snow cover at higher latitudes. Almost all ... -
Hvordan redusere risiko for mykotoksiner i korn?
Hofgaard, Ingerd Skow; Aamot, Heidi Udnes; Brodal, Guro; Lundon, Aina; Hjelkrem, Anne-Grete Roer; Lillemo, Morten; Strand, Einar (Journal article, 2020)Aksfusariose er en kornsjukdom som kan angripe alle kornarter. Sjukdommen forårsakes av sopparter innen slekta Fusarium. Ulike Fusarium-arter kan produsere en rekke forskjellige mykotoksiner (soppgifter). Grenseverdier for ... -
Microdochium majus and other fungal pathogens associated with reduced gluten quality in wheat grain
Aamot, Heidi Udnes; Lysøe, Erik; Koga, Shiori; Nielsen, Katherine Ann Gredvig; Böcker, Ulrike; Brodal, Guro; Dill-Macky, Ruth; Uhlen, Anne Kjersti; Hofgaard, Ingerd Skow (Peer reviewed; Journal article, 2020)The bread-making quality of wheat depends on the viscoelastic properties of the dough in which gluten proteins play an important role. The quality of gluten proteins is influenced by the genetics of the different wheat ... -
Microdochium nivale in perennial grasses : snow mould resistance, pathogenicity and genetic diversity
Abdelhalim, Mohamed (PhD Thesis;2016:32, Doctoral thesis, 2017-07-07)Forage production of perennial grass species in the northern hemisphere is limited by their winter survival ability. The predicted future changes in the environmental conditions constitute both opportunities and challenges ... -
Pathogenicity, host specificity and genetic diversity in Norwegian isolates of Microdochium nivale and Microdochium majus
Abdelhalim, Mohamed Ibrahim Mohamed; Brurberg, May Bente; Hofgaard, Ingerd Skow; Rognli, Odd Arne; Tronsmo, Anne Marte (Peer reviewed; Journal article, 2020)Microdochium majus and Microdochium nivale cause serious disease problems in grasses and cereal crops in the temperate regions. Both fungi can infect the plants during winter (causing pink snow mould) as well as under cool ... -
Risk assessment of mycotoxins in cereal grain in Norway. Opinion of the Scientific Steering Committee of the Norwegian Scientific Committee for Food Safety
Bernhoft, Aksel; Eriksen, Gunnar Sundstøl; Sundheim, Leif; Berntssen, Marc; Brantsæter, Anne Lise; Brodal, Guro; Fæste, Christiane Kruse; Hofgaard, Ingerd Skow; Rafoss, Trond; Sivertsen, Tore; Tronsmo, Anne Marte (VKM Report, Research report, 2013) -
Weather Patterns Associated with DON Levels in Norwegian Spring Oat Grain: A Functional Data Approach
Hjelkrem, Anne-Grete Roer; Aamot, Heidi Udnes; Lillemo, Morten; Sørensen, Espen Sannes; Brodal, Guro; Russenes, Aina Lundon; Edwards, Simon G.; Hofgaard, Ingerd Skow (Journal article; Peer reviewed, 2022)Fusarium graminearum is regarded as the main deoxynivalenol (DON) producer in Norwegian oats, and high levels of DON are occasionally recorded in oat grains. Weather conditions in the period around flowering are reported ...
