The endogenous auxin rescues the erf mutant phenotypes in the hypocotyl. (A) Six-day-old seedlings of the wild type, the er erl1 erl2 mutant and three independent pER:iaaM transgenic lines in the er erl1 erl2 mutant background (L2, L4 and L6). (B–D) PI staining of hypocotyls in the wild type (B), the er erl1 erl2 mutant (C) and three independent pER:iaaM transgenic lines in the er erl1 erl2 mutant background (D). The yellow line represents the length of a single cell. Scale bar in (A), 1 mm; scale bars in (B–D), 50 μm.
