Xyloglucan endotransglucosylase/hydrolase (XTH) overexpression affects growth and cell wall mechanics in etiolated Arabidopsis hypocotyls Ghent University University of Antwerp
Plant cell wall imaging by metabolic click-mediated labelling of rhamnogalacturonan II using azido 3-deoxy-D-manno-oct-2-ulosonic acid Ghent University
Reciprocal interactions between cadmium-induced cell wall responses and oxidative stress in plants. Hasselt University
Cadmium (Cd) pollution renders many soils across the world unsuited or unsafe for food- or feed-orientated agriculture. The main mechanism of Cd phytotoxicity is the induction of oxidative stress, amongst others through the depletion of glutathione. Oxidative stress can damage lipids, proteins, and nucleic acids, leading to growth inhibition or even cell death. The plant cell has a variety of tools to defend itself against Cd stress. First and ...
Long-term cadmium exposure influences the abundance of proteins that impact the cell wall structure in Medicago sativa stems Hasselt University
Cadmium (Cd) is a non-essential, toxic heavy metal that poses serious threats to both ecosystems and human health. Plants employ various cellular and molecular mechanisms to minimise the impact of Cd toxicity and cell walls function as a defensive barrier during Cd exposure. In this study, we adopted a quantitative gel-based proteomic approach (two-dimensional difference gel electrophoresis) to investigate changes in the abundance of cell wall ...
Cell wall digestibility of perennial ryegrass : an association mapping approach Ghent University
Lolium perenne L. (perennial ryegrass) is the most prevalent grass species on dairy farms in temperate regions of the world. Its energy content is among the highest of forage grasses, but not as high as that of more expensive concentrate, which is an essential part of a cow's diet to opti-mize milk yields. Increasing the available energy content of ryegrass, measured as the total digestibility (OMD), would be economically beneficial for the ...
Aluminum oxide nanoparticles affect the cell wall structure and lignin composition slightly altering the soybean growth Ghent University
Aluminum oxide (Al2O3) nanoparticles (NPs) are among the nanoparticles most used industrially, but their impacts on living organisms are widely unknown. We evaluated the effects of 50-1000 mg L-1 Al2O3 NPs on the growth, metabolism of lignin and its monomeric composition in soybean plants. Al2O3 NPs did not affect the length of roots and stems. However, at the microscopic level, Al2O3 NPs altered the root surface inducing the formation of cracks ...
Understanding the impact of main cell wall polysaccharides on the decomposition of ectomycorrhizal fungal necromass Hasselt University
The extramatrical mycelium of ectomycorrhizal fungi (EMF) is an important source of soil carbon and nitrogen. While the importance of recalcitrant compounds in the fungal cell wall has been explored earlier, the contribution of highly abundant but labile components, like glucans, and the role of their temporal dynamics during decomposition remains unknown. For the first time, we examined how the concentration of three main fungal cell wall ...
Extensin gene expression is induced by mechanical stimuli leading to local cell wall strengthening in Nicotiana plumbaginifolia Research Institute for Agriculture, Fisheries and Food
Nicotiana plumbaginifolia Viv. harbors a single extensin gene, although related hydroxyproline-rich sequences are present in the genome. Northern analysis showed that the gene is highly expressed in roots and to a lesser extent in stems. Expression in leaves is low but mRNA levels are increased upon infection with the incompatible bacterium Pseudomonas syringae. Extensin transcript levels in leaves were slightly enhanced after wounding and ...
