Can drought tolerance be a preadaptation to frost tolerance? : evolution of responses to drought and sudden frost within the grass subfamily Pooideae
Stolsmo, Sylvia Pal (Master thesis, 2019)The grass family (Poaceae) is one of the most economical and ecological important plant family on earth. The largest of the Poaceae grass subfamilies is Pooideae. This subfamily contains many of our crop and forage grasses ... -
Conservation and regulation of key photoperiod regulators in the Pooideae subfamily of grasses
Young, Darshan Anthony (Master thesis, 2018)Plants have adapted to seasonal constraints of the temperate environment by exploiting annual fluctuations in day length. Well timed flowering is essential to maximize reproductive output in temperate regions with short ... -
Cytisus scoparius : a genetic and historical analysis of introduction history in Norway
Furevik, Beate Beatriz (Master thesis, 2017-01-02)Cytisus scoparius is an invasive species threatening the local flora where the shrub is introduced. Studies show that the shrub spreads rapidly and has damaging effects in areas where the plant is considered invasive. ... -
Ecological effects of Cytisus scoparius invasion : a native or alien species?
Brandes, Ursula (PhD Thesis;2019:31, Doctoral thesis, 2019)The number of alien invasive species is continually increasing, threatening the environment and economy and their management is challenging. For cases of cryptic invasions, it is not even known if a species is native or ... -
Evolution of adaptations to temperate climate in the grass subfamily Pooideae
Schubert, Marian (PhD Thesis;2016:89, Doctoral thesis, 2016)Temperate biomes are characterized by strong temperature and photoperiod seasonality and frequently occurring frost. Temperate plants have evolved to overcome challenges like cold stress, prolonged winters and short ... -
Evolution of flowering adaptations in temperate grasses
Paliocha, Martin (PhD Thesis;2023:64, Doctoral thesis, 2023)Grasses (Poaceae) represent an unparalleled evolutionary success story and are particularly well adapted to the environmental challenges posed by temperate habitats. Crucial to their evolutionary success in temperate ... -
Evolution of growth rates in Pooideae (Poaceae)
Lindberg, Camilla Lorange (Master thesis, 2016)The temperate grasses in the subfamily Pooideae (Poaceae) has a limited distribution range The species are mainly distributed to the Northern Temperate regions and are known to be adapted to the strong seasonality this ... -
Flowering behaviour and juvenile stage miR156/miR172 expression in annual and perennial Pooideae
Hjertaas, Ane Charlotte (Master thesis, 2020)Most plant seedlings undergo a juvenile stage of development, during which they are unresponsive to environmental signals that promote floral competence. The length of this phase is often extended in perennial versus annual ... -
Molekylærgenetisk karakterisering av vernaliseringsrespons i PACMAD-gras
Paliocha, Martin (Master thesis, 2018)Many plants rely on a mechanism called vernalisation response to match reproductive output with favourable environmental conditions. This trait is an important adaptation to seasonal climates, like for example at high ... -
The temporal expression pattern of MND1 and key regulators of floral transition in annual and perennial Pooideae species
Molland, Martine (Master thesis, 2021)The molecular mechanisms underlying differences in annual and perennial life-history strategies are poorly understood. However, studies have shown that perennials often exhibit delayed flowering compared to related annuals. ... -
The perceived taste of lactic acid fermentation in protein hydrolysates : a screening of the sensory properties of lactic acid bacteria (LAB) implemented in hydrolysate products produced with co-products from the food industry (poultry-, fish- and dairy)
Rein, Magnus (Master thesis, 2018)The use of enzymatic protein hydrolysis is today common practise within the food industry to extract additional high quality nutritional components, however the method is rather limitedly used towards products for later ... -
Vernalization and photoperiodic regulation of flowering time and population genetic stucture of Norwegian populations of Arabidopsis thaliana
Lewandowska-Sabat, Anna M. (PhD Thesis;2009:44, Doctoral thesis, 2009)Natural environmental conditions vary across seasons and therefore timing of flowering is a major determinant of plant reproductive success and a trait with a potentially high adaptive value. Plants have developed mechanisms ...
