ers1 etr1 Mutants Exhibit an Extremely Compact Rosette, Delayed Flowering, and Stunted Inflorescence Stems.

(A) Rosette-stage phenotype of a 3-week-old ers1-2 etr1-7 homozygous mutant is shown next to a wild-type Columbia plant (at right) for comparison.

(B) ers1-2 etr1-6 homozygous mutants (far right) photographed next to an etr1 etr2 ein4 triple mutant and a ctr1-2 mutant for comparison. All plants were 6 weeks old.

(C) Close-up of a 12-week-old ers1-2 etr1-7 mutant that has not bolted. Bar = 1 cm.

(D) Close-up of a 10-week-old ers1-2 etr1-6 mutant that has bolted and produced flowers (plant size, ∼4 cm).
