N ickerson , N orton H. (Washington U., St. Louis, Missouri.) Sustained treatment with gibberellic acid of maize plants carrying one of the dominant genes Teopod and Corn‐grass. Amer. Jour. Bot. 47(10): 809–815. Illus. 1960.—Groups of field‐grown plants of 2 dominant maize mutants, Corn‐grass ( Cg ), and Teopod ( Tp ), were treated with either distilled water or with 1 of 3 concentrations of aqueous gibberellic acid (GA) every 3 days from the seedling stage until tassel emergence. Both dominant mutants were found to respond to GA in such manner that certain treated plants became essentially normal in phenotype. The role of GA in modifying expression of specific genes is briefly discussed.
