In vitro translation products of polyadenylated RNA from untreated and auxin-treated elongating sections of soybean (Glycine max var. Wayne) hypocotyl were analyzed by two-dimensional polyacrylamide gel electrophoresis. The levels of translatable messenger RNA for at least ten in vitro translation products are increased by auxin treatment. The induction by auxin occurs rapidly (within 15 minutes), and the amounts of the induced in vitro translation products increase with time of auxin treatment. Indoleacetic acid has the same effect on the population of translatable messenger RNA as 2,4-dichlorophenoxyacetic acid. The auxin-induced in vitro translation products disappear rapidly when Actinomycin D is present during the last two hours of a three-hour auxin treatment.
