Abstract excerpt
A spontaneous rice mutant, erect leaf1 (elf1-1), produced a dwarf phenotype with erect leaves and short grains. Physiological analyses suggested that elf1-1 is brassinosteroid-insensitive, so we hypothesized that ELF1 encodes a positive regulator of brassinosteroid signaling. ELF1, identified by means of positional cloning, encodes a protein with both a U-box domain and ARMADILLO (ARM) repeats. U-box proteins...
