gcn5 and hd1 Mutations Affect the Light Repression of Hypocotyl Elongation.

(A) Seven-day-old seedling hypocotyl lengths of wild-type Ws, gcn5, and hd1plantlets grown in darkness or under white light (16 h/d at 120 μmol·m−2·s−1) or continuous red (10 μmol·m−2·s−1) far-red (5 μmol·m−2·s−1), or blue (18 μmol·m−2·s−1) light.

(B) Seven-day-old far-red light–grown seedling phenotypes. Left, comparison of the gcn5-1 allele with the wild type (Ws); right, comparison of Ws, gcn5, gcn5 complemented with GCN5 cDNA [gcn5 (C)], hd1, and the double mutant gcn5 hd1-1. Means of 20 plantlets are given. Error bars represent sd values. The measures were analyzed by Student's t test at α = 0.05.
