Interactions between atmospheric CO2 and other environmental parameters will be investigated in controlled environments (growth chambers and greenhouses), raising crops to seed while regulating and monitoring atmospheric CO2, temperature, soil moisture and nutrition, and photosynthetically- as well as photomorphogenetically-active radiation. Growth chambers will simulate natural conditions. In addition, crops will be raised in the field; environmental conditions at various developmental stages will monitored and compared to those in controlled environments. In some cases, atmospheric CO2 will be regulated in the field (FACE, Free-Air CO2 Enrichment). Work will concentrate on soybeans, rice and peanuts. Seeds will be harvested and analyzed by HPLC for important biologically-active constituents, such as flavonoids, tocopherols, tocotrienols, sterols, saponins, and/or phylloquinone. Effects of environment on biosynthetic pathways will be evaluated.
