Evidence for Light-Stimulated Fatty Acid Synthesis in Soybean Fruit1

In leaves, the light reactions of photosynthesis support fatty acid synthesis but disagreement exists as to whether this occurs in green oilseeds. To address this question, simultaneous measurements of the rates of CO2 and O2 exchange (CER and OER, respectively) were made in soybean (Glycine max L.) fruits. The imbalance between CER and OER was used to estimate the diverted reductant utilization rate (DRUR) in the equation: DRUR = 4 x (OER + CER). This yielded a quantitative measure of the rate of synthesis of biomass that ...
