hen1-1 and hen1-2 single mutant phenotypes. (A–C) Rosettes of (A) a Ler, (B) a hen1-1 and (C) a hen1-2 plant, around the time of bolting. Rosette leaves in hen1-1 and hen1-2 tend to be pointed (arrows), and the edges tend to curl up slightly (arrowhead). (D) A hen1-1 plant containing the HEN1p10/p11 transgene. (E) A Ler (left) and a hen1-1 (right) mature flower at the same magnification. (F) A Ler and (G) a hen1-1 inflorescence. (H–J) Scanning electron micrographs of (H) a Ler, (I) a hen1-1 and (J) a hen1-2 mature leaf. (K–M) Scanning electron micrographs of (K) a Ler, (L) a hen1-1 and (M) a hen1-2 mature petal. Scale bars, 100 µm in H–J, and 10 µm in K–M.
