Allele: Locus: AGI code:
  • ga1-3
  • rga-2
  • ga1
  • rga

Phenotype

double mutant; partially represses several defects of the severe GA deficiency of ga1-3, including: stem growth (about 1/3 as tall as wt, compared to the extreme dwarf stature of ga1-3), leaf abaxial trichome initiation (one to three leaves later than wt), flowering time (flowers earlier than ga1-3, but not as early as wt), and apical dominance (intermediate branching between ga1-3 and wt).
