  author={M. H. O'leary},
he efficiency of photosynthesis continues to interest biochemists, biologists, and plant physiologists. Scientists interested in CO2 uptake are concerned about the extent to which the uptake rate is limited by such factors as stomatal diffusion and the chemistry of the CO2 absorption process. The fractionation of carbon isotopes that occurs during photosynthesis is one of the most useful techniques for investigating the efficiency of CO2 uptake. Atmospheric carbon dioxide contains approximately… Expand

Historical Aspects of Stable Isotopes in Plant Carbon and Water Relations
Publisher Summary This chapter discusses the historical aspects of stable isotopes in plant carbon and water relations. The linkage between 13C content and photosynthetic pathway type make itExpand
Photosynthetic Fractionation of Carbon Isotopes
During photosynthetic CO2 fixation fractionation of stable carbon isotopes occurs and, consequently, plants are generally depleted in the heavier isotope 13C. Carbon isotope discrimination (Δ) is aExpand
Soil Salinity Effect on Carbon Isotope Composition of Plant Biomass
The analysis of the carbon isotopic data available from the literature evidences in favor of the significant effect of salinity on plant and photosynthesizing alga biomass. The nature of this effectExpand
Carbon: terrestrial C4 plants
The carbon isotope composition of terrestrial C4 plants depends on the primary carboxylation of phosphoenolpyruvate (PEP) and on the diffusion of CO2 to the carboxylation sites, but is alsoExpand
Carbon isotope discrimination in leaf soluble sugars and in whole-plant dry matter in Helianthus annuus L. grown under different water conditions.
Publisher Summary The fractionation of carbon isotopes during photosynthesis involves biochemical and physical processes and is strongly influenced by the environment. Carbon isotope discriminationExpand
Carbon Isotope Discrimination and Plant Water-Use Efficiency
It has been known for a long time that the isotope fractionation of carbon formed by photosynthesizing plants varies radically depending on the pattern of photosynthesis in which the species isExpand

Direct quantification of photosynthetic carbon assimilation in seaweeds provides a valuable measure of primary production by these abundant macrophytes. Most photosynthetic studies with macroalgalExpand
The influence of water content and leaf anatomy on carbon isotope discrimination and photosynthesis in Sphagnum
The relative effect of diffusional resistance due to water films (r wf ) and leaf anatomy (r p ) on rates of net photosynthesis and on-line measures of carbon isotope discrimination (Δ = Δδ 13 C) wasExpand
Applications of Stable Isotope Technology in Physiological Ecology
The aim of the following article is to highlight methodological and theoretical constraints for any new study, to evaluate the current applications in physiological ecology, and to suggest some potential developments. Expand
Carbon isotope composition of plant photosynthetic tissues reflects a Crassulacean Acid Metabolism (CAM) continuum in the majority of CAM lineages
The diverse patterns of δ13C distribution in different plant families and sub-familial taxa are investigated and it is concluded that the evident continuum between CAM and C3 photosynthesis cautions against the usage of a δ 13C threshold in macroevolutionary studies. Expand


Carbon isotope fractionation in plants
Abstract Plants with the C 3 , C 4 , and crassulacean acid metabolism (CAM) photosynthetic pathways show characteristically different discriminations against 13 C during photosynthesis. For eachExpand
Fractionation of the carbon isotopes during photosynthesis
An attempt is made to explain quantitatively the fractionation of the carbon isotopes, 12C and 13C, in plants. It is shown that the isotope ratio in plants is mainly determined by the relativeExpand
Diffusional Contribution to Carbon Isotope Fractionation during Dark CO(2) Fixation in CAM Plants.
A mathematical model is developed which can be used to predict in vivo carbon isotope fractionations associated with carbon fixation in plants in terms of diffusion, CO(2) hydration, and carboxylation components, and indicates that the rate of carbon fixation is limited principally by diffusion, rather than by car boxylation.

Transport and fixation of inorganic carbon by marine algae
The chapter shows some of the properties of the in organic carbon system in seawater that are relevant to the assimilation of inorganic carbon by marine algae and cyanobacteria. Expand
On the Relationship Between Carbon Isotope Discrimination and the Intercellular Carbon Dioxide Concentration in Leaves
It is shown how diffusion of gaseous COz can significantly affect carbon isotopic discrimination and a simple relationship between discrimination and the ratio of the intercellular and atmospheric partial pressures of COZ is developed. Expand
Temperature Dependence of Carbon Isotope Fractionation in CAM Plants.
The small change in the isotopic composition of remaining malic acid in both species which is observed during deacidification indicates that malate release, rather than decarboxylation, is rate limiting in the deacidisation process. Expand
Carbon isotope discrimination measured concurrently with gas exchange to investigate CO2 diffusion in leaves of higher plants
Despite uncertainties about various processes affecting carbon isotope composition, the resistance to the transfer of CO2 from the intercellular airspaces to the sites of carboxylation in the mesophyll chloroplasts was estimated and is consistent with, and provides the first direct experimental support for, theoretical equations describing discrimination during photosynthesis.

In considering variations in the radiocarbon content of natural material, it is important to distinguish between processes of fractionation and of dilution; thus the accumulated data on C13Expand
Photosynthesis and the influence of CO2‐enrichment on δ13C values in a C3 halophyte
Analysis of carboxylases, CO2-enrichment studies, and gas exchange analysis indicated that intercellular CO2 concentrations were depressed in the leaves of salt-affected plants, consistent with a biophysical explanation for salt-induced shifts in †13C, whereby there is a steepening of the CO2 diffusion gradient into the leaf.

Short-term measurement of carbon isotope fractionation in plants.
This method will make possible a variety of new studies of environmental and species effects in carbon isotope fractionation, and give results consistent with what is expected from combustion studies of C(3), C(4), and Crassulacean acid metabolism plants. Expand
