Figure 1: PZA specifically suppresses the short-root and short-hypocotyl phenotype of eto1-2.

(a) 3-day-old etiolated seedlings of Col-0, eto1-2, ctr1-1 and ein2-5 grown on horizontally oriented MS only or MS medium supplemented with 50 μM PZA. Quantification of the hypocotyl lengths (b) and root lengths (c) of 3-day-old etiolated seedlings of Col-0, eto1-2, ctr1-1 and ein2-5 grown on MS only or MS medium supplemented with different concentrations of PZA (1, 5, 10, 20, 50 and 100 μM). Bars represent the average length (±s.d.) of fifteen seedlings (Student’s t-test, between PZA-treated and non-treated seedlings; **P<0.01).
