Accumulation of (Ag(I) by Saccharomyces cereviseae cells expressing plant metallothioneins
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 ... -
Allyl-isothiocyanate treatment induces a complex transcriptional reprogramming including heat stress, oxidative stress and plant defence responses in Arabidopsis thaliana
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 ... -
Altering the Glucosinolate Profile of Arabidopsis thaliana: Characterization and Impact on Resistance Against Botrytis cinerea
Hanssen, Vilde Wiig (Master thesis, 2017)The glucosinolate-myrosinase system is a well-known part of the Brassicacea plant immunity. This family includes several important crop species as well as the model organism Arabidopsis thaliana, thus encouraging and ... -
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
Moradi, Babak; Kissen, Ralph; Maivan, Hassan Zare; Hashtroudi, Mehri Seyed; Sorahinobar, Mona; Sparstad, Torfinn; Bones, Atle M. (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) -
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 ... -
The Role of a Glucosinolate-Derived Nitrile in Plant Immune Responses
Ting, Hieng Ming; Cheah, Boon Huat; Chen, Yu-Cheng; Yeh, Pei-Min; Cheng, Piu-Ching; Yeo, Freddy Kuok San; Vie, Ane Kjersti; Rohloff, Jens; Winge, Per; Bones, Atle M.; Kissen, Ralph (Peer reviewed; Journal article, 2020)Glucosinolates are defense-related secondary metabolites found in Brassicaceae. When Brassicaceae come under attack, glucosinolates are hydrolyzed into different forms of glucosinolate hydrolysis products (GHPs). Among the ... -
Study of HIPP25, HIPP26, HIPP27 gene expression and glucosinolate content in Arabidopsis thaliana and Noccaea caerulescens upon heavy metal treatments
Gautam, Barsanti (Master thesis, 2017)Hyperaccumulator plant species accumulate exceedingly high concentrations of metals in aerial parts and are increasingly studied because of their potential for cleaning up land contaminated with heavy metals. One such ... -
