DHGA₁₂ antagonistically suppresses the effect of ABA in seedling establishment. a, b Effects of exogenous application of DHGA₁₂ and GA₄ on cotyledon greening of wild-type, gas2-1, and gas2-2, germinated 10-d on MS and MS + 0.2 µM ABA, with or without the addition of DHGA₁₂ or GA₄. Bars = 1.5 cm. c, d Cotyledon greening analysis of wild-type, gas2-1, and gas2-1, grown on MS at day 4 (c) and MS + 0.2 µM ABA at day 7 (d), with or without the addition of DHGA₁₂ or GA₄. Error bars represent SD (n = 72, t test, *P < 0.05). Values are the mean of three independent experiments. e, f Effects of exogenous application of DHGA₁₂ and GA₄ on hypocotyl elongation of 5-d wild-type, gas2-1 and gas2-2 seedlings grown under continuous far-red light illumination. Data represent means ± SD (n = 22, t test, *P < 0.05). Source data are provided as a Source Data file. ABA abscisic acid
