Exogenous auxin rescues the cell elongation defects in the erf mutants. (A) PI staining of hypocotyls in the wild type, er-105 and er erl1 erl2 mutant grown in the 1/2MS media with or without 50 nM IAA. (B) The average cell lengths of the hypocotyls in the wild type, er-105 and er erl1 erl2 mutant grown in the 1/2MS media with or without 50 nM IAA. (n = 25). The yellow line represents the length of a single cell. Scale bars, 50 μm. Different letters represent statistically significant differences (P < 0.05), ANOVA-test.
