“…Arbuscular mycorrhizal associations are considered to play a key role in the acquisition of nutrients, and in particular phosphorus (Smith & Smith, 2012 Högy, Keck, et al, 2010;Singh et al, 2013), which is more than observed for rice and wheat, and similar to the average response observed for all C 3 crops ( Figure 2 (Uddling et al, 2018). In our 2005 review we noted that most of the decrease in plant N content was accounted for by a lower investment in Rubisco, a finding that is supported by subsequent FACE studies (Ainsworth & Long, 2005;Wang et al, 2020). With higher efficiency in elevated [CO 2 ] and a shift from Rubisco to RubP regeneration limitation, less Rubisco is needed as predicted both by metabolic modeling and least-cost optimality theory (Long et al, 2004;Smith & Keenan, 2020).…”

Free-air CO 2 enrichment (FACE) allows open-air elevation of [CO 2 ] without altering the microclimate. Its scale uniquely supports simultaneous study from physiology and yield to soil processes and disease. In 2005 we summarized results of then 28 published observations by meta-analysis. Subsequent studies have combined FACE with temperature, drought, ozone, and nitrogen treatments. Here, we summarize the results of now almost 250 observations, spanning 14 sites and five continents. Across 186 independent studies of 18 C 3 crops, elevation of [CO 2 ] by ca. 200 ppm caused a ca. 18% increase in yield under non-stress conditions. Legumes and root crops showed a greater increase and cereals less. Nitrogen deficiency reduced the average increase to 10%, as did warming by ca. 2°C. Two conclusions of the 2005 analysis were that C 4 crops would not be more productive in elevated [CO 2 ], except under drought, and that yield responses of C 3 crops were diminished by nitrogen deficiency and wet conditions. Both stand the test of time. Further studies of maize and sorghum showed no yield increase, except in drought, while soybean productivity was negatively affected by early growing season wet conditions. Subsequent study showed reduced levels of nutrients, notably Zn and Fe in most crops, and lower nitrogen and protein in the seeds of non-leguminous crops. Testing across crop germplasm revealed sufficient variation to maintain nutrient content under rising [CO 2 ]. A strong correlation of yield response under elevated [CO 2 ] to genetic yield potential in both rice and soybean was observed. Rice cultivars with the highest yield potential showed a 35% yield increase in elevated [CO 2 ] compared to an average of 14%. Future FACE experiments have the potential to develop cultivars and management strategies for co-promoting sustainability and productivity under future elevated [CO 2 ].

“…Based on the Representative Concentration Pathway (RCP) Scenario 8.5 of the Intergovernmental Panel on Climate Change [2], atmospheric temperature could rise by as much as 4.8˚C by around 2100 and the CO 2 concentration could reach 940 μmol mol -1 . These predicted increases in atmospheric CO 2 concentration and temperature are anticipated to affect crop productivity and quality [3][4][5]. However, each crop variety exhibits different response patterns to changes in temperature and CO 2 concentration [6][7][8].…”

The effect of concurrent elevation in CO2 and temperature on the growth, photosynthesis, and yield of potato crops

et al. 2020

Global climate change accompanied by continuous increases in atmospheric carbon dioxide (CO 2) concentration and temperature affects the growth and yield of important crops. The present study investigated the effect of elevated temperature and CO 2 concentrations on the growth, yield, and photosynthesis of potato (Solanum tuberosum L. cv. Superior) crops using Korean Soil-Plant-Atmosphere-Research chambers that allow the regulation of temperature and CO 2 concentration under daylight conditions. Based on the average temperature from 1991 to 2010 in the Jeonju area, South Korea, potato plants were exposed to four different conditions: ambient weather (400 μmol mol-1 , aCaT), elevated temperature (+4˚C, aCeT), elevated CO 2 concentration (800 μmol mol-1 , eCaT), and concurrently elevated CO 2 concentration and temperature (eCeT). Under aCeT conditions, the temperature exceeded the optimal growth temperature range towards the late growth phase that decreased stomatal conductance and canopy net photosynthetic rate and subsequently reduced biomass and tuber yield. Stomatal conductance and chlorophyll concentration were lower under eCaT conditions than under aCaT conditions, whereas late-growth phase biomass and tuber yield were greater. Compared to other conditions, eCeT yielded a distinct increase in growth and development and canopy net photosynthetic rate during tuber initiation and bulking. Consequently, biomass and canopy net photosynthesis increased, and tuber yield increased by 20.3%, which could be attributed to the increased tuber size, rather than increased tuber number. Elevated CO 2 reduced chlorophyll, magnesium, and phosphorus concentrations; reducing nitrogen concentration (by approximately 39.7%) increased the C: N ratio. The data indicate that future climate conditions will likely change nutrient concentration and quality of crops. The present study shows that while elevated temperature may negatively influence the growth and yield of potato crops, especially towards the late-growth phase, the concurrent and appropriate elevation of CO 2 and temperature could promote balanced development of source and sink organs and positively effect potato productivity and quality.

“…The method for controlling CO 2 and temperature in situ has been described in detail by Cai et al [ 31 ] and Wang et al [ 32 , 33 ]. The temperature and free-air CO 2 enrichment (T-FACE) system is characterized by six rings located within a paddy field with a similar soil and cultivation history.…”

Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS), versus attenuated total reflectance spectroscopy (FTIR-ATR) and diffuse reflectance spectroscopy (DRIFT), was firstly applied in quick assessment of rice quality in response to rising CO2/temperature instead of conventional time-consuming chemical methods. The influences of elevated CO2 and higher temperature were identified using FTIR-PAS spectra by principal component analysis (PCA). Variations in the rice functional groups are crucial indicators for rice identification, and the ratio of the intensities of two selected spectral bands was used for correlation analysis with starch, protein, and lipid content, and the ratios all showed a positive linear correlation (R2 = 0.9103, R2 = 0.9580, and R2 = 0.9246, respectively). Subsequently, changes in nutritional components under future environmental conditions that encompass higher CO2 and temperature were evaluated, which demonstrated the potential of FTIR-PAS to detect the responses of rice to climate change, providing a valuable technique for agricultural production and food security.
