Genetic interactions between abs1-1D and various mutants with altered photomorphogenic growth. (A) Phenotypes of representative 3-week-old wild-type, abs1-1D, det2-1 and abs1-1D det2-1 double mutant plants. (B) Comparison of hypocotyl elongation of 1-week-old wild-type, abs1-1D, det2-1, and abs1-1D det2-1 double mutant plants grown in the dark. (C) Phenotypes of representative 2-week-old wild-type, abs1-1D/+ heterozygote, abs1-1D homozygote, bes1-D/+ heterozygote, bes1-D/+ abs1-1D/+ double heterozygote and bes1-D homozygote plants. (D) Comparison of hypocotyl elongation of 1-week-old Arabidopsis Landsberg erecta ecotype (Ler), phyB-1 mutant, two independent transgenic lines overexpressing ABS1 in a phyB-1 mutant background, and Arabidopsis Columbia ecotype (Col) grown in the light.
