Independent recruitment of FRUITFULL-like transcription factors in the convergent origins of vernalization-responsive grass flowering
Paliocha, Martin; Schubert, Marian; Preston, Jill Christine; Fjellheim, Siri (Peer reviewed; Journal article, 2023)Flowering in response to low temperatures (vernalization) has evolved multiple times independently across angiosperms as an adaptation to match reproductive development with the short growing season of temperate habitats. ... -
Introduction history and population genetics of intracontinental scotch broom (Cytisus scoparius) invasion.
Brandes, Ursula; Furevik, Beate Beatriz; Nielsen, Lene Rostgaard; Kjær, Erik Dahl; Rosef, Line; Fjellheim, Siri (Peer reviewed; Journal article, 2019)Abstract Aim: Biological invasions at the intracontinental scale are poorly studied, and intracontinental invasions often remain cryptic. Here, we investigate the recent range expansion of scotch broom (Cytisus ... -
Local populations of Arabidopsis thaliana show clear relationship between photoperiodic sensitivity of flowering time and altitude
Lewandowska-Sabat, Anna; Fjellheim, Siri; Olsen, Jorunn Elisabeth; Rognli, Odd Arne (Journal article; Peer reviewed, 2017) -
Major niche transitions in Pooideae correlate with variation in photoperiodic flowering and evolution of CCT domain genes
Fjellheim, Siri; Young, Darshan Anthony; Paliocha, Martin; Johnsen, Sylvia Sagen; Schubert, Marian; Preston, Jill Christine (Peer reviewed; Journal article, 2022)The external cues that trigger timely flowering vary greatly across tropical and temperate plant taxa, the latter rely- ing on predictable seasonal fluctuations in temperature and photoperiod. In the grass family (Poaceae) ... -
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) shows adaptation of grass pollen composition
Diehn, Sabrina; Zimmermann, Boris; Bagcioglu, Murat; Seifert, Stephan; Kohler, Achim; Ohlson, Mikael; Fjellheim, Siri; Weidner, Steffen; Kneipp, Janina (Journal article; Peer reviewed, 2018)MALDI time-of-flight mass spectrometry (MALDI-TOF MS) has become a widely used tool for the classification of biological samples. The complex chemical composition of pollen grains leads to highly specific, fingerprint-like ... -
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 ... -
Multiscale vibrational spectroscopy of pollen
Bağcıoğlu, Murat (PhD Thesis;2016:10, Doctoral thesis, 2020-11-19)Pollen has a vital role in the reproduction of flowering plants by producing genetically diverse offspring via pollination. Environmental effects have strong influence on reproductive structures of plants, including on ... -
Phenotypic responses to light, water, and nutrient conditions in the allopolyploid Arabidopsis suecica and its parent species A. thaliana and A. arenosa: Does the allopolyploid outrange its parents?
Kornstad, Torbjørn H; Ohlson, Mikael; Fjellheim, Siri (Peer reviewed; Journal article, 2022) -
Population structure, genetic variation and linkage disequilibrium in perennial ryegrass populations divergently selected for freezing tolerance
Kovi, Mallikarjuna Rao; Fjellheim, Siri; Sandve, Simen Rød; Larsen, Arild; Rudi, Heidi; Asp, Torben; Kent, Matthew Peter; Rognli, Odd Arne (Journal article; Peer reviewed, 2015) -
Shedding light on the role of seasonal flowering in plant niche transitions

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. ... -
Testing the chilling- before drought-tolerance hypothesis in Pooideae grasses
Das, Aayudh; Dedon, Natalie; Enders, Daniel J.; Fjellheim, Siri; Preston, Jill C. (Peer reviewed; Journal article, 2022) -
The grass subfamily Pooideae: Cretaceous–Palaeocene origin and climate‐driven Cenozoic diversification
Schubert, Marian; Marcussen, Thomas; Meseguer, Andrea S.; Fjellheim, Siri (Peer reviewed; Journal article, 2019) -
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 ... -
The role of seasonal flowering responses in adaptation of grasses to temperate climates
Fjellheim, Siri; Boden, Scott; Trevaskis, Ben (Journal article; Peer reviewed, 2014) -
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 ... -
What’s the meaning of local? Using molecular markers to define seed transfer zones for ecological restoration in Norway
Jørgensen, Marte Holten; Elameen, Abdelhameed; Hofman, Nadine; Klemsdal, Sonja; Malaval, Sandra; Fjellheim, Siri (Journal article; Peer reviewed, 2016)According to the Norwegian Diversity Act, practitioners of restoration in Norway are instructed to use seed mixtures of local provenance. However, there are no guidelines for how local seed should be selected. In this ...
