Ruta, Lavinia L; Banu, Melania A.; Neagoe, Aurora D; Kissen, Ralph; Bones, Atle M.; Farcasanu, Ileana C. (Journal article; Peer reviewed, 2018)The various applications of Ag(I) generated the necessity to obtain Ag(I)-accumulating organisms for the removal of surplus Ag(I) from contaminated sites or for the concentration of Ag(I) from Ag(I)-poor environments. In ... -

Kissen, Ralph; Øverby, Anders; Winge, Per; Bones, Atle M. (Journal article; Peer reviewed, 2016)Background Isothiocyanates (ITCs) are degradation products of the plant secondary metabolites glucosinolates (GSLs) and are known to affect human health as well as plant herbivores and pathogens. To investigate the processes ... -

Anchoring plant metallothioneins to the inner face of the plasma membrane of Saccharomyces cerevisiae cells leads to heavy metal accumulation
Ruta, Lavinia Liliana; Lin, Ya-Fen; Kissen, Ralph; Nicolau, Ioana; Neagoe, Aurora Daniela; Ghenea, Simona; Bones, Atle M.; Farcasanu, Ileana Cornelia (Journal article; Peer reviewed, 2017)In this study we engineered yeast cells armed for heavy metal accumulation by targeting plant metallothioneins to the inner face of the yeast plasma membrane. Metallothioneins (MTs) are cysteine-rich proteins involved in ... -
Arabidopsis mutants impaired in glutathione biosynthesis exhibit higher sensitivity towards the glucosinolate hydrolysis product allyl-isothiocyanate
Urbancsok, Janos; Bones, Atle M.; Kissen, Ralph (Journal article; Peer reviewed, 2018)Upon tissue damage the plant secondary metabolites glucosinolates can generate various hydrolysis products, including isothiocyanates (ITCs). Their role in plant defence against insects and pest and their potential health ... -
Assessment of oxidative stress response genes in Avicennia marina exposed to oil contamination - Polyphenol oxidase (PPOA) as biomarker

(Peer reviewed; Journal article, 2020)Mangrove plants, which inhabit and form sensitive ecosystems in the intertidal zones of tropical and subtropical coastlines, though vulnerable to petroleum pollution, still maintain their growth under oil contamination. ... -
Benzyl Cyanide Leads to Auxin-Like Effects Through the Action of Nitrilases in Arabidopsis thaliana
Urbancsok, Janos; Bones, Atle M.; Kissen, Ralph (Journal article; Peer reviewed, 2018)Plants within the Brassicales order generate glucosinolate hydrolysis products that can exert different biological effects on several organisms. Here, we evaluated the physiological effects of one of these compounds, benzyl ... -
Characterization of Arabidopsis thaliana transgenic lines expressing synthetic heavy metal binding oligopeptides
Habberstad, Vilde Pedersen (Master thesis, 2017)Heavy metal pollution is an increasing environmental problem, and their bio-toxic effects are of great concern. Some organisms have developed strategies to withstand metal excess. A particular case is the so-called metal ... -
Endogenous biological effects induced by externally supplemented glucosinolate hydrolysis products (GHPs) on Arabidopsis thaliana
Urbancsok, János (Doctoral theses at NTNU;2018:138, Doctoral thesis, 2018) -
Engineering the microalga Phaeodactylum tricornutum to remediate heavy metal polluted water: An attempt to increase its heavy metal tolerance and uptake
Kjønnøy, Christine Gerd Cooper (Master thesis, 2021)Tungmetallforurensning er et stort problem over hele verden og er et resultat av økende antropogeniske aktiviteter. Likevel, er de eksisterende teknologiene for fjerning av tungmetaller antatt å være dyre, ødeleggende for ... -
Glucosinolate-Derived Isothiocyanates Inhibit Arabidopsis Growth and the Potency Depends on their Side Chain Structure
Urbancsok, Janos; Bones, Atle M.; Kissen, Ralph (Journal article; Peer reviewed, 2017)Isothiocyanates (ITCs), the biologically important glucosinolate breakdown products, can present health-promoting effects, play an important role in plant defense and affect plant cellular mechanisms. Here, we evaluated ... -
Heat stress response is part of the isothiocyanate-induced response in Arabidopsis thaliana
Koldingsnes, Jakob (Master thesis, 2016)Heat stress responses (HSR) represent a multi-pathway system of adaptive responses to environmental changes. Common downstream targets of HSR pathways are the heat shock proteins, amongst them HSP101 (At1g74310). In ... -
