Indoleacetic acid (IAA) stimulates the incorporation of radioactivity derived from methionine-methyl-C14 into a fraction of sesbania hypocotyl that is insoluble in 80 per cent alcohol or 60 percent acetone, but is soluble in hot water. Incorporation of C14 into “hot water soluble material” was stimulated by IAA, 2,4-dichlorophenoxyacetic acid, 2,5-dichlorophenoxyacetic acid, 2,4,5-trichlorophenoxyacetic acid, naphthaleneacetic acid, 2,3,6-trichlorophenylacetic acid, 2-methoxy-3,6-dichlorobenzoic acid, 4-amino-2,5-dichlorobenzoic acid, and 4-amino-3,5,6-trichloropicolinic acid. All compounds were stimulative at 1 × 10-5M.
