| Abstract: | Developing soybean cotyledons rapidly incorporated acetate intofatty acids and water soluble constituents. Oleic acid was thefirst fatty acid to be detected with 14C and the 14C distributionpattern with time was consistent with its being the precursorof linoleic and linolenic acids. Palmitic or stearic acid didnot appear to be the precursor of oleic acid but appeared tobeformed parallel to it. The cotyledons did fix 14CO2 by eitherdark or light fixation reactions but little 14C was incorporatedinto lipids. 1Presented in part at the Midwest Section of the American Societyof Plant Physiologist Meeting in Columbia, Missouri, June 1970 (Received November 27, 1970; ) |
