Arabidopsis thaliana THESEUS1 modulates phytohormone responses induced by plant cell wall damage
Stratton, Christian Henry (Master thesis, 2020)Plantecelleveggen er den definerende strukturen til landplanter som tillot dem å nå sine til tider imponerende størrelser, men vår forståelse av prosessene som opprettholder celleveggintegritet (CWI) er ekstremt begrenset. ... -
Cell wall integrity maintenance during plant development and interaction with the environment
Vaahtera, Lauri; Schulz, Julia; Hamann, Thorsten (Journal article; Peer reviewed, 2019)Cell walls are highly dynamic structures that provide mechanical support for plant cells during growth, development and adaptation to a changing environment. Thus, it is important for plants to monitor the state of their ... -

Chp8, a diguanylate cyclase from pseudomonas syringae pv. Tomato DC3000, suppresses the pathogen-associated molecular pattern flagellin, increases extracellular polysaccharides, and promotes plant immune evasion
Engl, C; Waite, C.; McKenna, J; Bennett, M; Hamann, Thorsten; Buck, M. (Journal article; Peer reviewed, 2014)The bacterial plant pathogen Pseudomonas syringae causes disease in a wide range of plants.

Current status of the multinational Arabidopsis community.
Hamann, Thorsten; Parry, G; provart, Nicholas; brady, siobhan; uzilday, b (Peer reviewed; Journal article, 2020)The multinational Arabidopsis research community is highly collaborative and over the past thirty years these activities have been documented by the Multinational Arabidopsis Steering Committee (MASC). Here, we (a) highlight ... -
Functional analysis of cell wall integrity signalling processes in Arabidopsis thaliana
Starheim, Svanhild Johannessen (Master thesis, 2021)Plantecellers cellevegg fungerer som strukturell støtte og beskytter cellene mot miljøstress. Celleveggens integritet (CWI) opprettholdes av en dedikert mekanisme for celleveggintegritetsvedlikehold (CWIM) og bedre forståelse ... -
Functional characterization of ATSFH19 (At5g47730)
Hoel, Håkon (Master thesis, 2019)The plant cell wall is a structure that is essential to the growth and development of plants. It provides the plant with both structural support and a defense against the environment and herbivores. Damage to the plant ... -
Functional characterization of five genes implicated in cell wall integrity maintenance in Arabidopsis thaliana
Ørnhaug Solem, Ruben (Master thesis, 2022)Celleveggen sikrar plantecella si struktur og vernar mot stress frå omverda. Ein naudsynt molekylær mekanisme står difor til grunne for å halde celleveggsstoda ved like, og dermed også planteveksten. Ei god forståing for ... -
Functional characterization of genes mediating cell wall metabolism and responses to plant cell wall integrity impairment.
Engelsdorf, Timo; Kjær, Lars; Gigli-Bisceglia, Nora; Vaahtera, Lauri; Bauer, Stefan; Miedes, Eva; Wormit, Alexandra; James, Lucinda; Chairam, Issariya; Molina, Antonio; Hamann, Thorsten (Journal article; Peer reviewed, 2019) -
Glycerol-3-phosphate and cell wall integrity maintenance mechanism - two sides to the same story?
Svanø, Kristine Marie (Master thesis, 2018)Plants and pathogens are in a constant "arms-race", with the plant cell wall as one of the main battlefields. This arms-race have evolved to complex defense responses in plants against primary infections in local infected ... -
Investigating the effects of osmotic stress and cellulose biosynthesis inhibition on cell morphology and plasma membrane tension in Arabidopsis thaliana using confocal microscopy and the mechanosensitive Flipper-TR
Moe, Pernille Sofie (Master thesis, 2022)Planter trenger et system for å oppfatte og tilpasse seg miljøet rundt, ettersom de ikke kan forflytte seg. Plantecellen er omgitt av en cellevegg som støtter opp planten strukturelt og mekanisk. Mekanismene for ... -
Investigating the prospect of using the yellow fluorescent protein mutant YFP3G as a pressure sensor in plants
Indregard, Eskil Nodeland (Master thesis, 2018)Plants have no skeleton, but instead get their structural support from a hydrostatic pressure called turgor pressure pressing against a strong cell wall. This pressure can reach up to 2 MPa, and is also an important part ... -
Outside-in control - does plant cell wall integrity regulate cell cycle progression?
Gigli, Nora; Hamann, Thorsten (Journal article; Peer reviewed, 2018)During recent years it has become accepted that plant cell walls are not inert objects surrounding all plant cells but are instead highly dynamic, plastic structures. They are involved in a large number of cell biological ... -
Plant Biology: Plants Turn Down the Volume to Respond to Cell Swelling.
Hamann, Thorsten; Bacete, Laura (Peer reviewed; Journal article, 2020)Turgor manipulation to induce plant cell swelling is one of the classic experiments undertaken in biology courses in schools and at universities. However, only now do we start to understand the molecular mechanisms responsible ... -
