Genetic Relationship between MYB30 and phyA/phyB.

(A) Phenotypes and hypocotyl lengths of Col, phyB-9, myb30-1, and myb30-1 phyB-9 seedlings grown in W light (10 µmol m⁻² s⁻¹) or R light (60 µmol m⁻² s⁻¹) for 4 d.

(B) Phenotype and hypocotyl lengths of Col, phyA-211, myb30-1, and myb30-1 phyA-211 seedlings grown in W light (10 µmol m⁻² s⁻¹) or FR light (5 µmol m⁻² s⁻¹) for 4 d.

Error bars represent sd from at least 15 seedlings. ***, P < 0.001 (Student’s t test; Supplemental Data Set 3) for the indicated pairs of seedlings. Bar in (A) and (B) = 1 mm.
