Photorespiration results from the oxygenase reaction catalysed by ribulose-1,5-bisphosphate carboxylase/oxygenase. In this reaction glycollate-2-phosphate is produced and subsequently metabolized in… Expand
The regulation and control of photorespiration
The role of photorespiration during drought stress : an analysis utilizing barley mutants with reduced activities of photorespiratory enzymes
The significance of photorespiration in drought-stressed plants was studied by withholding water from wild-type barley (Hordeum vulgare L.) and from heterozygous mutants with reduced activities of… Expand

The aim of this study was to determine the response of photosynthetic carbon metabolism in spinach and bean to low temperature. (a) Exposure of warm-grown spinach and bean plants to 10 degrees C for… Expand
C3 and C4 Pathways of Photosynthetic Carbon Assimilation in Marine Diatoms Are under Genetic, Not Environmental, Control1[W][OA]
Marine diatoms are responsible for up to 20% of global CO2 fixation. Their photosynthetic efficiency is enhanced by concentrating CO2 around Rubisco, diminishing photorespiration, but the mechanism… Expand
Regulation of Leaf Senescence by Cytokinin, Sugars, and Light: Effects on NADH-Dependent Hydroxypyruvate Reductase
The aim of this study was to investigate the interactions between cytokinin, sugar repression, and light in the senescence-related decline in photosynthetic enzymes of leaves. In transgenic tobacco… Expand
The effect of water stress on photosynthetic carbon metabolism in four species grown under field conditions
Abstract. The effect of gradually-developing water-stress has been studied in Lupinus albus L., Helianthus annuus L., Vitis vinifera cv. Rosaki and Eucalyptus globulus Labill. Water was withheld and… Expand
C4 photosynthesis: principles of CO2 concentration and prospects for its introduction into C3 plants

C(4) photosynthesis has a number of distinct properties that enable the capture of CO(2) and its concentration in the vicinity of Rubisco, so as to reduce the oxygenase activity of Rubisco, and hence… Expand
Control of photosynthesis in barley plants with reduced activities of glycine decarboxylase
Abstract. A mutant (LaPr 87/30) of barley (Hordeum vulgare L.) deficient in glycine decarboxylase (GDC; EC 18.104.22.168) was crossed with wild-type plants to generate heterozygous plants with reduced GDC… Expand
