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.
