BBX19 Suppression of Photomorphogenesis Is Mediated by PIF4/5.

(A) and (C) Phenotypes of 5-d-old seedlings from various genotypes (Col-0, OE44, pifq, OE44/pifq, and single pif mutant/OE44 combinations) grown under LD conditions.

(B) and (D) Hypocotyl lengths of the genotypes in (A) and (C), respectively.

(E) Hypocotyl phenotypes of Col-0, BBX19-overexpressing (OE44), RNAi (Ri323), pif4/5 double mutant, and OE44/pif4/5 seedlings grown under LD conditions.

(F) Measurements of hypocotyl lengths of the genotypes in (E).

For (B), (D), and (F), data are means ± sd; n ≥ 90. Letters above the bars indicate significant differences as determined by Tukey’s HSD method (P < 0.05).
