Intraspecific, Interspecific, and Seasonal Variation in Acclimation of Photosynthesis to Rising Atmospheric Carbon Dioxide Concentration
… Enrichment (FACE) experiment with Glycine max (SoyFACE); a FACE experiment with Lolium perenne, a temperate grassland species (Swiss FACE); and an open-top chamber experiment within a clonal Florida scruboak ecosystem. In these experiments, photosynthesis was measured with an open-gas exchange …

Interactions between oxidative stresses in corn
… Disease surveys were conducted at the SoyFACE facility at Champaign, IL, during the 2013, 2014 and 2015 seasons. Naturally occurring foliar and ear disease were evaluated on a visual damage scale, while stalk rot was evaluated on the basis of presence/absence basis. The most commonly …

Direct and Indirect Effects of Elevated Carbon Dioxide and Ozone on the Canopy of a Soybean Agroecosystem
… E&barbelow;nrichment technology (SoyFACE) with plots exposed to ambient air (∼370ppm), elevated CO2 (∼550ppm) and elevated O3 (1.2*ambient). Elevated [CO2] increased maximum LAI and delayed LAI loss to senescence, although the effects varied among years. Elevated [O3] …

Improved Temperature Response Functions for Modeling Photosynthetic Carbon Assimilation in the Context of Rising Carbon Dioxide
… made over the growing season in the PopFACE and SoyFACE research facilities located in Viterbo, Italy and Urbana, IL, respectively. These provided a rigorous test of the utility of the new functions in predicting the CO2 response of photosynthesis with daily and seasonal variation in temperature …

Soybean's Future: Photosynthesis, Sucrose Transport, Dry Mass Accumulation and Yield in a Changing Atmosphere
… and seed yield by 34% and 24%, respectively. SoyFACE (SOYbean Free Atmosphere gas Concentration Enrichment, www.soyface.uiuc.edu), a facility that elevates [O 3] (1.2x current) or [CO2] (550 p.p.m.), provided a unique opportunity to analyze the effects of these two gases under open-air …

Current and future consequences of tropospheric ozone on soybean biochemistry, physiology and yield
… the Soybean Free Air Concentration Enrichment (SoyFACE) facility in 2007, and six of those were grown again in 2008. In order to determine what parameters could be used to predict the sensitivity of seed yield to elevated [O3], photosynthetic gas exchange, fluorescence, chlorophyll content, …

Impacts of global warming and rising atmospheric CO2 concentrations on physiology, development and productivity of Midwestern crops
… in terms of CO2 and temperature, at the SoyFACE research facility in Champaign, IL. For soybean, photosynthesis, growth and yield were reduced with high temperatures and increased with elevated CO2. However, rising both CO2 and temperature produced a variable response that was dependent …

Interactive effects of elevated carbon dioxide concentration and water availability on field-grown soybean (Glycine max)
… at the soybean Free-Air CO2 Enrichment (soyFACE) facility, where soybean was grown in the field at ambient [CO2] or elevated [CO2], as predicted for the middle of this century. I analyzed an eight year field study to test the hypothesis that reduced gs in elevated [CO2] will overwhelm …

Optimality and resilience in patterns of carbon allocation and growth in vegetation under acclimation response to climate change
… in a soybean agricultural system at the SoyFACE research facility in Illinois. Our modeling results indicate that the acclimation response of plants significantly alters the land surface fluxes of water, carbon and energy thereby impacting the hydrologic cycle. They confirm the widely …

Dynamics of soybean leaf hydraulic conductance and diurnal soybean transcriptome analysis
… studies and with field-grown soybean at the SoyFACE site in Champaign, IL. Because the expected responses of photosynthesis and transpiration to elevated [CO2] and elevated temperature are well documented, we hypothesized that Kleaf would acclimate in line with photosynthesis and …

The role of environment, sink capacity, and carbon translocation in determining C3 plant responses to elevated [CO2]
… date, and agronomic traits, were grown at SoyFACE from 2003 to 2008. There was significant intraspecific variation in yield response to elevated [CO2], with shorter cultivars and those with high harvest index showing greater response to elevated [CO¬2]. Harvest index is an indicator of sink …

Developmental and physiological responses of soybean to elevated growing temperatures
… on plants. This project was carried out at the SoyFACE research facility in Champaign, Illinois. Commercial soybean varieties from maturity groups (MG) 3.6 and 4.2 were planted under ambient conditions and four different elevated heat treatments (+1.5, +3.0, +4.5, +6.0 oC) from 2017-2019. Using …

Impacts of heat waves on food quantity and quality of soy bean/corn in the Midwest at ambient and elevated [CO2]
… field. Heat wave research was conducted at the SoyFACE research facility in Urbana, IL. Thirty years of climate data from Central Illinois were analyzed to determine the characteristics of a historically plausible, yet extreme heat wave. Heat waves were defined as 3 day long events where canopy …

Hydrogen peroxide from photosynthesis: Theory and experiments linking elevated atmospheric CO2 with C3 plant chemical defense
… At the same time, soybean grown at the soyFACE (Free Air CO2 Enrichment) field site were tested for their response to sudden transitions from dark-to-bright light under ambient and elevated CO2. Both in-silico modeling and field experiments are consistent with the initial hypothesis. …

Plant root contributions to the carbon balance of a changing agricultural Midwest
The long-term carbon balance of the agricultural Midwestern United States will depend on the interactions between climate, land use decisions, plant biology, and biogeochemistry. In agricultural systems, C storage is fully determined by belowground pools, so it is vital to understand the links …
