Phenotype analysis of the hda6/etc1 double mutant. A, Cross sections of root tips of etc1 and hda6/etc1. Bars = 20 μm. B, Quantification of the root epidermal cellular pattern of the hda6/etc1 double mutant, showing frequencies of ectopic developing nonhair cells (blue bars) and ectopic developing hair cells (red bars). At least 12 root tips were analyzed for each line. The mean and sd are indicated for each line. *, P < 0.05, Student’s t test. C, Seven-day-old seedlings bearing the ETC1pro:GUS reporter gene were stained for GUS activity. WT, Wild type. Bars = 50 μm.
