(a) Wild type Col-0 and the F4 generation triple mutant h1.1-1 h1.2-1 h1.3-1 plants at 6 weeks old. The h1.1-1 h1.2-1 h1.3-1 mutant plant shows delay in flowering and small stature.
(b) Wild type Col-0 and the F4 generation triple mutant h1.1-1 h1.2-1 h1.3-1 plants at 10 weeks old. The h1.1-1 h1.2-1 h1.3-1 mutant plant shows delayed flowering, small stature and is almost infertile.
(c) Siliques of wild type Col-0 and the F4 generation triple mutant h1.1-1 h1.2-1 h1.3-1 plant. The mutant siliques are shorter and have fewer or no seeds.
