The process of photorespiration diminishes the efficiency of CO(2) assimilation and yield of C(3)-crops such as wheat, rice, soybean or potato, which are important for feeding the growing world population. Photorespiration starts with the competitive inhibition of CO(2) fixation by O(2) at the active site of ribulose-1,5-bisphosphate carboxylase/oxygenase(More)
In most studies, amounts of protein complexes of the oxidative phosphorylation (OXPHOS) system in different organs or tissues are quantified on the basis of isolated mitochondrial fractions. However, yield of mitochondrial isolations might differ with respect to tissue type due to varying efficiencies of cell disruption during organelle isolation procedures(More)
The oxidation of glycolate to glyoxylate is an important reaction step in photorespiration. Land plants and charophycean green algae oxidize glycolate in the peroxisome using oxygen as a co-factor, whereas chlorophycean green algae use a mitochondrial glycolate dehydrogenase (GDH) with organic co-factors. Previous analyses revealed the existence of a GDH in(More)
The mitochondrial NADH dehydrogenase complex (complex I) is of particular importance for the respiratory chain in mitochondria. It is the major electron entry site for the mitochondrial electron transport chain (mETC) and therefore of great significance for mitochondrial ATP generation. We recently described an Arabidopsis thaliana double-mutant lacking the(More)
INTRODUCTION Many patients undergoing bariatric surgery report current or past psychiatric disorders and controversy exists regarding their outcome after bariatric surgery. PRESENTATION OF CASE We present a case of an obese patient with a borderline personality disorder, a recurrent depressive disorder, post-traumatic stress symptoms and binge eating(More)
Climate change and the increasing world population will lead to an increased water shortage. This gives rise to the need for plant cultivars which are drought tolerant. Solanum tuberosum L. is important not only as a nutritive rich food, but starch potatoes are of great value for the industry. Two starch genotypes of S. tuberosum L. divergently responding(More)
