The primary effect of the response of plants to rising atmospheric CO2 (Ca) is to increase resource use efficiency. Elevated Ca reduces stomatal conductance and transpiration and improves water use efficiency, and at the same time it stimulates higher rates of photosynthesis and increases light-use efficiency. Acclimation of photosynthesis during long-term exposure to elevated Ca reduces key enzymes of the photosynthetic carbon reduction cycle, and this increases nutrient use efficiency… Expand

Plant Responses to Increased Carbon Dioxide
TLDR
Improved understanding of plant N dynamics and fine and cause of RuBisCO coupled to balancing sink numbers is the basis of developing crops for a carbon rich future. Expand
Development of Water Stress under Increased Atmospheric CO2 Concentration
The increase in water use efficiency (the ratio of photosynthetic to transpiration rates) is likely to be the commonest positive effect of long-term elevation in CO2 concentration (CE). This may notExpand
Response of nodulated alfalfa to water supply, temperature and elevated CO2: productivity and water relations
Exposing plants to long-term CO2 enrichment generally leads to increases in plant biomass, total leaf area and alterations on leaf net photosynthetic rates, stomatal conductance and water useExpand
Crop Growth Responses Towards Elevated Atmospheric CO2
The projected rise in global elevated atmospheric CO2 level has well-pronounced impact on plant ecophysiology and economic productivity. Elevated atmospheric CO2 accelerated the leaf-levelExpand
Physiological Response of Maize Under Rising Atmospheric CO2 and Temperature
The projections for future climate change may have a strong influence on agricultural productivity. Maize, being a C4 plant, has evolved to adapt to the atmospheric CO2 concentration with higherExpand
Photosynthesis in a CO2-Rich Atmosphere
The concentration of CO2 ([CO2]) in the atmosphere is projected to exceed 550 ppm by 2050. C3 plants respond directly to growth at elevated [CO2] by stimulation of photosynthesis and reduced stomatalExpand
Application of transgenic plants in understanding responses to atmospheric change
TLDR
This article summarizes studies with transgenic plants grown in elevated pCO 2 which are modified in their capacity of CO 2 fixation, of sucrose and starch synthesis, of triosephosphate and sucrose transport and of sink metabolism of Sucrose. Expand
Photosynthesis, Growth, and Yield of Citrus at Elevated Atmospheric CO2
TLDR
There is indeed a critical need to unravel the mechanisms of citrus responses to atmospheric [CO2] enrichment and climate changes, and to identify the targets for a genetic/breeding approach designed to enhance citrus tolerance/resistance to environmental stresses. Expand
Effect of Elevated Levels of Carbon Dioxide on the Activity of RuBisCO and Crop Productivity
Atmospheric CO2 concentration is now higher than it was at any time in the past 26 million years and is expected to nearly double during this century. This trend is of concern to agriculture becauseExpand
Stomatal sensitivity to photosynthetic and environmental signals in glycine max grown at elevated atmospheric concentrations of CO2 and O3
Rising atmospheric concentrations of carbon dioxide (CO 2) and ozone (O 3) will stimulate and impair, respectively, yield and productivity of both managed and natural ecosystems in the 21 st century.Expand

Effects of source‐sink relations on photosynthetic acclimation to elevated CO2
TLDR
The data presented in this paper suggest that plants growing in the field will maintain a high photosynthetic capacity as the atmospheric CO2 level continues to rise. Expand

Abstract. Climate change will include correlated increases in temperature and atmospheric CO2 concentration (Ca). Rising temperatures will increase the ratio of photorespiratory loss of carbon toExpand
A meta‐analysis of leaf gas exchange and nitrogen in trees grown under elevated carbon dioxide
The response of trees to rising atmospheric CO2 concentration ([CO2]) is of concern to forest ecologists and global carbon modellers and is the focus of an increasing body of research work. I reviewExpand
Stomatal responses to increased CO2: implications from the plant to the global scale
Increased atmospheric CO 2 often but not always leads to large decreases in leaf conductance. Decreased leaf conductance has important implications for a number of components of CO 2 responses, fromExpand

Abstract. Herbaceous C3 plants grown in elevated CO2 show increases in carbon assimilation and carbohydrate accumulation (particularly starch) within source leaves. Although changes in theExpand
The effect of an elevated atmospheric CO2 concentration on growth, photosynthesis and respiration of Plantago major
TLDR
It is suggested that in P. major, a rosette plant, self-shading causes a decline in photosynthesis and results in an increase in the shoot: root ratio and a decrease in RGR, and CO2-enriched plants grow faster and cosequently suffer more from self- shading. Expand
Responses of respiration to increasing atmospheric carbon dioxide concentrations
It has been recently recognized that increases in carbon dioxide concentration such as are anticipated for the earth's atmosphere in the next century often reduce plant respiration. There can be bothExpand
Nitrogen nutrition of C3 plants at elevated atmospheric CO2 concentrations
The atmospheric CO 2 concentration has risen from the preindustrial level of approximately 290 μl l -1 to more than 350 μl l -1 in 1993. The current rate of rise is such that concentrations of 420 μlExpand
Increased photosynthetic capacity of Scirpus olneyi after 4 years of exposure to elevated CO2
TLDR
An increase in photosynthetic capacity has been observed in other species growing in the field, which suggests that photosynthesis of certain field grown plants will continue to respond to elevated levels of atmospheric CO2. Expand
