Fig 1. The response of the shy2-3 mutant to light.

(A) Hypocotyl phenotype of 4-day-old seedlings of Ler and shy2-3 mutant under white light (WL) at different fluence rates (151, 65, 27, and 17 μmol·m⁻²·s⁻¹) with or without the treatment of auxin synthesis inhibitors (Kyn and PPBo). Bar = 1 mm. (B) Quantification of the hypocotyl length of wild-type Ler and shy2-3 under the same conditions described in (A). Error bars represent SD (n ≥ 15 seedlings).
