Fragrance production in petunia flowers is highly regulated. Two transcription factors, ODORANT1 (ODO1) and EMISSION OF BENZENOIDS II (EOBII) have recently been identified as regulators of the volatile benzenoid/phenylpropanoid pathway in petals. Unlike the non-fragrant Petunia hybrida cultivar R27, the fragrant cultivar Mitchell highly expresses ODO1. Using stable reporter lines, we identified th
Industrial waste dumps are rarely colonized by vegetation after they have been abandoned, indicating biological infertility. Revegetation of industrial tailings dumps is thus necessary to prevent wind erosion, metal leaching and has been shown to restore soil functions and ecosystem services. However, little is known about the microbial colonization and community structure of vegetated tailings fo
Background: Ribonucleotide reductases (RNRs) catalyze the formation of the deoxyribonucleotides that are essential for DNA synthesis. The R2 subunit of Escherichia coli RNR is a homodimer containing one dinuclear iron centre per monomer. A tyrosyl radical is essential for catalysis, and is formed via a reaction in which the reduced, diferrous form of the iron centre activates dioxygen. To help und
The chemical composition of foraminiferal calcite is widely used for studying past environmental conditions and biogeochemistry. However, high rates of microbial organic matter degradation and abundant dissolved metal sources in sediments and pore waters may impede the application of foraminifera-based proxies due to formation of secondary carbonates or other authigenic minerals on and/or inside o
Perfluoroalkyl substances (PFAS) are man-made, highly persistent and mobile compounds that have been extensively used in decades, for example as a fire repellent in aqueous film-forming foam (AFFF). They have been detected in soil, surface water and groundwater, where they pose risks to human health through contamination of drinking water supplies and to ecosystems. In this case study, PFAS spread
This paper describes the potential help that the interactive desktop concept can bring to the execution of embodiment design tasks. The presented project is still in its infancy. The research framework is the following: once a product concept has been approved, the mechanical design engineer develops the product architecture and product part (also called embodiment design). Sketches at that level
Rättsutlåtande Svenaeus 2020-05-11 1 Fil.dr. Lena Svenaeus RÄTTSUTLÅTANDE Detta rättsutlåtande skrivs på uppdrag av klagande i mål 113/20 vid Förvaltningsrätten i Malmö. Syftet är att belysa lagligheten av Skurups kommuns beslut att i förskola och skola förbjuda huvudduk och viss annan religiös klädsel för skolpersonal och elever.

Predicted alterations in belowground plant-allocated C as a result of environmental change may cause compositional shifts in soil microbial communities, and it has been hypothesized that such alterations will influence C mitigation in forest ecosystems. In order to investigate to what degree living trees influence the abundance and activity of mycorrhizal fungi, saprotrophic fungi, and bacteria we
REVEALS-based quantitative reconstruction of Holocene vegetation cover (expressed in plant functional types. PFTs) is used in the LANDCLIM project to assess the effect of human-induced land-cover change on past climate in NW Europe. Using the Czech Quaternary Pollen Database, this case study evaluates the extent to which selection of data and input parameters for the REVEALS model applications wou
The predominantly populated conformation of carbohydrates in solution does not necessarily represent the biologically active species; rather, any conformer accessible without too large an energy penalty may be present in a biological pathway. Thus, the conformational preferences of a naphthyl xyloside, which initiates in vivo synthesis of antiproliferative glycosaminoglycans, have been studied by
The sugar binding specificities of two groups of Streptococcus suis, a pig pathogen that causes meningitis also in man, were determined. Both the group represented by a recently characterized strain inhibitable by galactose and N-acetylgalactosamine (type PN) and the group inhibitable by galactose (type PO) were found by hemagglutination and solid-phase binding inhibition experiments to recognize
