PIF4–Mediated Activation of YUCCA8 Expression Integrates Temperature into the Auxin Pathway in Regulating Arabidopsis Hypocotyl Growth

The shy2-2 Mutation Suppresses the Long-Hypocotyl Phenotype of 35S-PIF4 Seedlings.
(A) Representative images showing that shy2-2 suppresses the long-hypocotyl phenotype of 35S-PIF4. Shown are 6-d-old seedlings of Col-0, Ler, shy2-2, 35S-PIF4 and 35S-PIF4/shy2-2 grown at 22°C. (B) Hypocotyl length showing that shy2-2 suppresses the long-hypocotyl phenotype of 35S-PIF4. Hypocotyl length of six-d-old seedlings of the indicated genotypes grown at 22°C was measured. Data shown are average±SD. Student's t-test between mutant/transgenic and wild-type seedlings was performed (**, P<0.01). Shown are representative data from one biological replicate; three biological replicates were conducted, yielding similar results.
