Hypersensitivity of pif3, pif4, and pif7 to Prolonged Rc Is Additive.
(A) Visual phenotypes of 4-d-old Rc-grown (10 μmol·m−2·s−1) wild-type and pif seedlings.
(B) Hypocotyl length in 4-d-old Rc-grown wild-type and pif seedlings. Rc fluence rate was 0.8 μmol·m−2·s−1 for seedlings in all panels except for the middle right panel, in which it was 0.3 μmol·m−2·s−1. Mean and se values are representative of at least 25 seedlings.
