Balance Between C3 and CAM Pathway of Photosynthesis
1976Apart from primary photosynthetic CO2 fixation by RuDP carboxylase (“C3 photosynthesis”), photosynthetic mechanisms are observed among higher plants by which primary CO2 fixation is catalyzed by PEP carboxylase with formation of oxalo-acetic acid (OAA).

Effect of phosphinothricin (glufosinate) on photosynthesis and photorespiration of C3 and C4 plants
Photosynthesis Research, 1990Phosphinothricin (glufosinate), an irreversible inhibitor of glutamine synthetase, causes an inhibition of photosynthesis in C3 (Sinapis alba) and C4 (Zea mays) plants under atmospheric conditions (400 ppm CO2, 21% O2). This photosynthesis inhibition is proceeding slower in C4 leaves. Under non-photorespiratory conditions (1000 ppm CO2, 2% O2) there is

Interreaction between Photorespiration and Photosynthesis in C3 Plants
1987Photorespiration, the O2-and light-dependent release of CO2 in C3 plants, is a curious process which inseparable from photosynthesis. Study on the relationship between the two process, which has not been known well, is important to understand the function of photorespiration and its effects on efficience of photosynthesis in crop plants.

Relationships between growth, photosynthesis and competitive interactions for a C3 and C4 plant
Oecologia, 1981The relationships of photosynthetic characteristics to the competitive interactions of a C3 plant, Chenopodium album, and a C4 plant, Amaranthis retroflexus, were investigated in different temperature and water supply regimes. Both species had similar photosynthetic rates at 25°C, but at higher temperatures, Amaranthus had substantially greater rates ...

Effects of irradiance and temperature on photosynthesis in C3, C4 and C3/C4 Panicum species
Photosynthesis Research, 1986Species in the Laxa and Grandia groups of the genus Panicum are adapted to low, wet areas of tropical and subtropical America. Panicum milioides is a species with C3 photosynthesis and low apparent photorespiration and has been classified as a C3/C4 intermediate. Other species in the Laxa group are C3 with normal photorespiration.

Palaeoecology, past climate systems, and C3/C4 photosynthesis
Chemosphere, 1993The geologic record shows unequivocally that the present world is unusually cold; the so called ‘greenhouse’ condition has been normal for planet Earth for the past 500 million years. Continental positions, orbital parameters, and atmospheric composition strongly influence global climate on timescales ranging from 108 to 102 years.

Evaluating the role of Rubisco regulation in photosynthesis of C3 plants
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1989Abstract The enzyme ribulose 1,5-bisphosphate carboxylase (Rubisco) catalyses the entry of carbon dioxide into photosynthetic metabolism, provides acceptor molecules that consume the products of the light reactions of photosynthesis, and regulates the pool sizes of important photosynthetic intermediates.

Differential sensitivity to humidity of daily photosynthesis in the field in C3 and C4 species
Oecologia, 1983Net photosynthesis was measured under field conditions in Maryland, U.S.A. on several days in the C4 species Amaranthus hybridus and Portulaca oleracea, and the C3 species Chenopodium album. Two similar fully exposed canopy leavesof the same specieswere measured each day, following ambient patterns of air temperature and irradiance.

C3 Photosynthesis in Algae: The Importance of Inorganic Carbon Concentrating Mechanisms
1987At low concentrations of inorganic carbon, unicellular algae and cyanobacteria require a ’Co2-concentrating’ mechanism to sustain high rates of photosynthesis. Air-grown cells of Synechococcus possess well-developed transport systems for Co2 and HCO3-. Hco3 - transport requires Na+ and is inhibited by Li+ whereas Co2 transport is not affected by either
