Unraveling the gene regulators and molecular mechanisms underlying the elevated CO2 response in C3 plants
Rising atmospheric carbon dioxide ([CO2]) concentrations, a major driver of climate change, also present a unique opportunity to enhance crop productivity, particularly in C3 plants. However, the extent of this CO2 fertilization effect is modulated by complex interactions with nutrient …

The photoprotective role of thermonastic leaf movements in Rhododendron maximum: potential implications to early spring carbon gain
… gas exchange parameters as measured by light and CO2 response curves did not indicate any significant difference between treatment and reference leaves post canopy closure. Out results suggest that TLM are an important mechanism for photoprotection, allowing leaves of R. maximum to recover quickly …

Ecophysiological responses of Themeda triandra Forsk. and other Southern African Câ‚„ grass species to increases in atmospheric COâ‚‚ concentrations
… growth, and morphological development. Altered CO2-responsiveness with simultaneous exposure to other environmental influences was also assessed in order to estimate the impacts of elevated CO2 on the future distribution and productivity of grasslands in southern Africa. The initial hypothesis …

The combined effect of daylength and CO2 on coccolithophore physiology
Atmospheric CO2 levels have been increasing at an accelerated rate for the last 250 years, much of which is absorbed by the oceans, resulting in a process called ocean acidification (OA). This phenomenon has the capacity to disrupt many marine biological processes that utilise carbon, in particular …

Improved Temperature Response Functions for Modeling Photosynthetic Carbon Assimilation in the Context of Rising Carbon Dioxide
Predicting environmental responses of leaf photosynthesis is central for modeling changes in the future global carbon cycle and terrestrial biosphere. The steady-state biochemical model of C3 photosynthesis of Farquhar et al. (1980; Planta 149, 78--90) provides a basis for these larger scale …

Stomatal regulation in C4 photosynthesis
… and C<sub>4</sub> plants, comparing their responses to changes in light and CO</sub>2</sub>. To control for potential confounding effects not related to photosynthetic type, three phylogenetically-controlled species from Cleomaceae, *Flaveria*, and *Alloteropsis* were used in the study. …

Links between climate feedbacks and the large-scale circulation across idealized and complex climate models
The circulation response to anthropogenic forcing is typically considered in one of two distinct frameworks: One that uses radiative forcings and feedbacks to investigate the thermodynamics of the response, and another that uses circulation feedbacks and thermodynamic constraints to investigate the …

The role of environment, sink capacity, and carbon translocation in determining C3 plant responses to elevated [CO2]
Over the past century, CO2 concentration ([CO2]) in the atmosphere has been steadily increasing, leading to global climate change. Elevated [CO2] increases yield, biomass, and photosynthesis in most C3 plants, but the degree to which elevated [CO2] stimulates crop yields can depend upon climatic …
