The effect of atmospheric CO2 concentration on carbon isotope fractionation in C3 land plants
Because atmospheric carbon dioxide is the ultimate source of all land-plant carbon, workers have suggested that pCO2 level may exert control over the amount of C incorporated into plant tissues. However, experiments growing plants under elevated pCO2 in both chamber and field settings, as well as meta-analyses of ecological and agricultural data, have yielded a wide range of estimates for the e...
متن کاملEffects of elevated CO2 concentration on seed production in C3 annual plants.
The response of seed production to CO(2) concentration ([CO(2)]) is known to vary considerably among C(3) annual species. Here we analyse the interspecific variation in CO(2) responses of seed production per plant with particular attention to nitrogen use. Provided that seed production is limited by nitrogen availability, an increase in seed mass per plant results from increase in seed nitrogen...
متن کاملPhotosynthesis of C3, C3–C4, and C4 grasses at glacial CO2
Most physiology comparisons of C3 and C4 plants are made under current or elevated concentrations of atmospheric CO2 which do not reflect the low CO2 environment under which C4 photosynthesis has evolved. Accordingly, photosynthetic nitrogen (PNUE) and water (PWUE) use efficiency, and the activity of the photosynthetic carboxylases [Rubisco and phosphoenolpyruvate carboxylase (PEPC)] and decarb...
متن کاملGlyphosate Resistance of C3 and C4 Weeds under Rising Atmospheric CO2
The present paper reviews current knowledge on how changes of plant metabolism under elevated CO2 concentrations (e[CO2]) can affect the development of the glyphosate resistance of C3 and C4 weeds. Among the chemical herbicides, glyphosate, which is a non-selective and post-emergence herbicide, is currently the most widely used herbicide in global agriculture. As a consequence, glyphosate resis...
متن کاملControls on Photosynthesis and Sugar Production in C3 and C4 Plants: a Modeling Approach
Photosynthesis is a rather complicated process (Figure 1). Along the pathway, there are a series of energy transformations, redox reactions, and entry and exit points, any of which could influence the rate of the overall process. However, physiological measurements yield surprisingly simple relationships among a few environmental factors such as light and CO2 availability and overall rates of p...
