Lektor

Research area: Plant biology, including plant physiology, biochemistry and molecular biology.

My Research is mainly been focussed on two related areas:

  • Phosphate sensing and assimilation.

    Phosphate is a major nutrient in plants. During phosphate starvation, plants adapt in several ways to increase uptake and optimise utilization of phosphate. We study regulations of gene expression in respose to altered phosphate availability eg. by combining nutrient analysis, hydroponics, isolation and characterisation of T-tagged Arabidopsis mutants and transgenic plants with altered phosphate sensing. One focus within this research area is studying a specific family of transcription factors involved in phosphate stress response. Most recently, I have also engaged in research om producing poly-phosphate in higher plants.

  • Regulation of carbohydrate metabolism in plants.

    Regulation of enzymes involved in biosynthesis of major compounds like sucrose and starch. Presently I am also inovlved in investigating fructan accumulation in temperate grass species. The metabolic analysis includes quantification of a range of key metabolites and flux analysis by radiolabelig studies, purification and characterization of regulatory enzymes, and production and characterization of transgenic plants and recombinant enzymes produced in microbes.
