Since the industrial revolution global atmospheric [CO2] has been increasing steadily (1.5 mmol mol-1 year-1) and is expected to increase from 365 mmol mol-1 (actual) to 700 mmol mol-1 by the end of the 21st century. Tropospheric O3 concentration is also increasing globally, especially in areas of high pollution. Elevated atmospheric [CO2] generally enhances photosynthesis by increasing intercellular CO2 concentration, which decreases photorespiration. Exposure to O3 generally decreases photosynthesis (Heath, 1994), probably by causing oxidative damage to cell membranes, including thylakoids. Soybean isoflavones are important as potentially bioactive compounds with impact in human chronic diseases like cancer. There is a lack of knowledge as to how changes in environmental atmospheric gas conditions affect soybean seed composition. In order to evaluate the effects of high CO2 or high O3 on the isoflavone concentration of soybean seeds, a soybean FACE (Free Air Concentrated Enrichment - SoyFACE) facility situated on an 80-acre field (32 ha; South Farms, University of Illinois at Urbana-Champaign; 40°03'21.3"N, 88°12'3.4"W, 230 m elevation) was used. Seeds of eight cultivars were collected during Summer 2002 at three different parts of the plant at harvesting stage. Results indicate that changes in atmospheric concentration of CO2 or O3 can have different effects on the isoflavone concentration in soybean seed depending on the variety evaluated. In general, high CO2 increased the isoflavone content while high O3 caused a dramatic decrease in isoflavones.
