Open AccessTwo decades of fumigation data from the Soybean Free Air Concentration Enrichment facility
The Soybean Free Air Concentration Enrichment (SoyFACE) facility is the longest running open-air carbon dioxide and ozone enrichment facility in the world. For over two decades, soybean, maize, and other crops...

Removal of redox-sensitive Rubisco Activase does not alter Rubisco regulation in soybean
Rubisco activase (Rca) facilitates the catalytic repair of Rubisco, the CO2-fixing enzyme of photosynthesis, following periods of darkness, low to high light transitions or stress. Removal of the redox-regulated ...

Towards a multiscale crop modelling framework for climate change adaptation assessment
Predicting the consequences of manipulating genotype (G) and agronomic management (M) on agricultural ecosystem performances under future environmental (E) conditions remains a challenge. Crop modelling has th...

Open AccessUncertainty in measurements of the photorespiratory CO2 compensation point and its impact on models of leaf photosynthesis
Rates of carbon dioxide assimilation through photosynthesis are readily modeled using the Farquhar, von Caemmerer, and Berry (FvCB) model based on the biochemistry of the initial Rubisco-catalyzed reaction of ...

Intensifying drought eliminates the expected benefits of elevated carbon dioxide for soybean
Stimulation of C3 crop yield by rising concentrations of atmospheric carbon dioxide ([CO2]) is widely expected to counteract crop losses that are due to greater drought this century. But these expectations come f...

Productivity of North American grasslands is increased under future climate scenarios despite rising aridity
The interacting effects of temperature and precipitation changes on grasslands remain hard to quantify. Research now indicates widespread and consistent increases in North American grassland productivity under...

Altered Belowground Carbon Cycling Following Land-Use Change to Perennial Bioenergy Crops
Belowground carbon (C) dynamics of terrestrial ecosystems play an important role in the global C cycle and thereby in climate regulation. Globally, land-use change is a major driver of changes in belowground C...

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 stomatal conductance....

Predicting the risk of soybean rust in Minnesota based on an integrated atmospheric model
To minimize crop loss by assisting in timely disease management and reducing fungicide use, an integrated atmospheric model was developed and tested for predicting the risk of occurrence of soybean rust in Min...

Modeling the Temperature Dependence of C3 Photosynthesis
The steady-state C3 model of photosynthesis originally developed by Graham Farquhar et al. (1980) and subsequently modified by others describes responses of leaf carbon assimilation to environmental variation. Th...

The growth of soybean under free air [CO2] enrichment (FACE) stimulates photosynthesis while decreasing in vivo Rubisco capacity
Down-regulation of light-saturated photosynthesis (Asat) at elevated atmospheric CO2 concentration, [CO2], has been demonstrated for many C3 species and is often associated with inability to utilize additional ph...
