The ERECTA family genes controls cell elongation in the hypocotyl. (A–D) PI staining of hypocotyls in the 6-day-old wild-type (A), 35S::ERECTA plant (B), er-105 mutant (C) and er erl1 erl2 mutant (D). (E) Average individual cell lengths of the hypocotyls in the 6-day-old wild-type, 35S::ERECTA plant, er-105 mutant and er erl1 erl2 mutant (n = 25). (F) Total cell number in the hypocotyls of 6-day-old wild-type, 35S::ERECTA plant, er-105 mutant and er erl1 erl2 mutant (n = 25). The yellow line represents the length of a single cell. Scale bars, 50 μm. ANOVA-test in (F), same letters represent no statistically significant differences (P < 0.05). Student’s t-test in (E), ∗P < 0.05.
