DHGA₁₂ can directly bind to the GA receptor (GID1c). a Microscale thermophoresis (MST) analysis of DHGA₁₂ and GA4 binding to GID1c. Dissociation constants of DHGA₁₂ and GA₄ with GID1c are 1.45 ± 0.25 μM and 0.68 ± 0.12 μM, respectively. Error bars represent SD (n = 3). b, c Effect of exogenous application of 5 μM DHGA₁₂ and 5 μM GA₄ on hypocotyl elongation of 10-d wild-type and gid1a-1/1b-1 seedlings grown under continuous far-red light illumination. Data represent means ± SD (n = 15; t test; *P < 0.05). Bar = 1.5 cm. Source data are provided as a Source Data file. GA gibberellins
