Abstract
Plant growth and biomass production are strongly dependent on nitrogen availability in soils. This explains why so many studies focused on nitrogen metabolism. However, interactions between nitrogen status and primary metabolic pathways, such as amino acid metabolism together with physiological processes such as respiration, are not as complete. In order to elucidate these interactions and their dynamics, the present PhD project includes three parts, (i) characterization of mutants exhibiting modified nitrogen status and disturbed respiratory metabolism, (ii) transcriptomic, metabolomic and isotope-based fluxomic studies, (iii) physiological parameter measurements under various environmental conditions.
