Fig. 1. Identification and characterization of the dwarf mutant Gmuid1.

a Representative image of plants from the wild-type (WT) Hedou 12 (H12) and the Gmuid1 mutant at the vegetative stage in the field. b Representative images of the WT and Gmuid1 at the R8 stage (full maturity). Scale bar, 10 cm. c Internode length of WT and Gmuid1 plants at the R8 stage. Data are means ± standard deviation (SD), n = 6 independent plants. d Summary of the positional cloning of the GmUID1 (also named GmILPA1) locus to chromosome 11. The insertion/deletion (InDel) markers Gm1005 and Gm0069 were used for initial mapping. GmUID1 (GmILPA1) was fine-mapped to a 68-kb region between the single sequence repeat (SSR) markers Gm1015 and Gm1016 on chromosome 11. n represents individual F₂/F₃ plants with the mutant phenotype. e Representative images of H12, Gmilpa1-2 (Gmuid1), Gmilpa1, Gmilpa1-2 × Gmilpa1 F1, and Gmilpa1-2 35S:GmILPA1 plants at the R1 stage (beginning of flowering). Scale bar, 10 cm. Source data are provided as a Source Data file.
