Photosynthesis Inhibition in the Arabidopsis Thaliana Photorespiration Mutants
… of photosynthesis occurring in the Arabidopsis photorespiration mutants during illumination under atmospheres which promote photorespiration is predominantly due to declining leaf RuBP concentrations resulting from the impairment of carbon recycling to the Calvin cycle.

Developmental and Expression Evolution in C3 and C4 Atriplex and their Hybrids
… photosynthesis and yield are reduced 30-50% by photorespiration. The C4 photosynthetic pathway incorporates biochemical and structural features to minimize photorespiration by concentrating CO2 around Rubisco. Engineering C4 into C3 crops requires an understanding of the molecular and genetic …

Änderung der Glycindecarboxylase- und Serinhydroxymethyltransferase-Aktivität in Blättern:
In C3/C4-intermediären Pflanzenarten wird die Photorespiration durch Kompartimentierung der photorespiratorischen CO2-Freisetzung aus Glycin in den Bündelscheidenzellen vermindert. Dieser CO2-Konzentrierungsmechanismus beruht auf der ausschließlichen Kompartimentierung der Glycindecarboxylase …

Morphological and Physiological Studies of the Carbon Concentrating Mechanism in Chlamydomonas reinhardtii
… RuBisCO oxygenase activity and associated photorespiration. The enhanced efficiency of CO2 assimilation in the pyrenoid via CCM had been modelled theoretically as a requirement for successful CCM in higher plant systems. The ultimate aim of my research is to understand the biogenesis of the …

The eco-physiology of New Zealand forest lichens with special reference to carbon dioxide exchange
… was considered to result from the repression of photorespiration. The oxygen effect was separated into two components; (a) the sensitivity of the carboxylation system and (b), the rate of CO₂ evolution in the light at zero CO₂. Of the lichen species studied all but P. billardierii had a …

Light utilization and excretion of organic matter by antarctic lake phytoplankton
… that the reduction of photosynthesis due to photorespiration might be limiting the development of the phytoplankton communities of these lakes.

Synthetic Biology for Autotrophic and Heterotrophic Production of Ethanol
… and O<sub>2</sub> which can lead to photorespiration and ultimately the loss of fixed carbon and nitrogen. The 3-hydroxypropionate (3-HPA) bypass was introduced into ethanol-producing Anabaena strain in an attempt to increase CO<sub>2</sub>-fixation and then increase ethanol …

Genome scale metabolic modelling of Phaeodactylum tricornutum
… with the Calvin cycle, reductant transfer, photorespiration, TCA cycle, glyoxylate cycle, lipid metabolism, carbohydrate metabolism and energy dissipation mechanisms under changing environmental and physiological conditions. Carbon xation and triose-phosphate production can take place solely …

Proteome studies on leaf peroxisomes from Spinacia oleracea L. and Arabidopsis thaliana (L.) Heynh.
… Peroxisomen hinaus, beispielsweise die in Photorespiration, Fettsäure-beta-Oxidation und den Metabolism reaktiver Sauerstoffspezies involvierten Enzyme, wurde einige neue Proteine identifiziert, und zwar eine kurzkettige Alkoholdehydrogenase, ein Naphthoat-Synthase-ähnliches Protein, eine …

Pre-industrial to 2000 ppm; soybean response to increasing CO2
… with increases in [CO2] due to the decrease in photorespiration; however, above a certain threshold, the benefits of continued increases in [CO2] will diminish. The data show that physiological development was delayed as [CO2] increased. Plant height and total leaf area increased with higher …

The role of small RNAs in C4 photosynthesis
… that are targeted to overcome the effects of photorespiration caused by the oxygenase capability of Ribulose Bisphosphate Carboxylase/Oxygenase (RuBisCO). The cycle has evolved independently in over 60 lineages, which suggests that recruitment of genes into the C4 cycle is a relatively easy …

A Proteomics Approach to the Examination of Proteins in Marine Systems
… photosynthetic energy production, enhancement of photorespiration, and increased polysaccharide production. This application of proteomics to the examination of proteins in marine sediments, a marine diatom, and a heterotrophic marine bacterium shows the potential for these techniques to help …

A Theoretical Approach to Guiding Biotechnological Improvement of Crop Photosynthetic Efficiency
… against environmental conditions that promote photorespiration. The model of primary events around PSII includes all energy and electron transfer in and around photosystem II. This model successfully simulates the fluorescence induction kinetics. Simulations using this model provide theoretical …

Potential Impacts of Climate Change on Photochemistry of <i>Zostera Marina</i> L.
… its physiological limits at pH 6.2 by minimizing photorespiration, and increased the light requirement to saturate photosynthesis. The instantaneous increase of photosynthesis up to 8 fold reduced the role of alternative electron pathways and non-photochemical quenching for photoprotection, …

Environmental Controls on Foliar Respiration in Arctic Plants
… such as foliar photosynthesis, respiration, photorespiration, mitochondria and chloroplast size and density, and physical leaf traits. Due to the extreme photoperiod experienced by arctic vegetation, respiration in the light (estimated using the Kok method) was quantified in addition to dark …
