Summary

The metabolism of [1,3-14C] acetone by plant tissues has been examined. Under the experimental conditions used, 14C of methyl labelled acetone was rapidly incorporated into CO2, organic acids, amino acids, lipids and into the insoluble residue. In pea cotyledons and beet leaves, acetate and formate together contained the bulk of the radioactivity of the organic acid fraction. The possibility is discussed that acetone, accumulating during the early stages of germination in peas may be subsequently metabolized as seedling development takes place.
