Fig. 1. Inflorescence and floral phenotypes of hen2-1 mutants. (A) Ler; (B) hua1-1 hua2-1; (C) hen2-1 hua1-1 hua2-1, petals are small and third whorl organs are a mosaic of sepal-petal tissue (arrows). (D-G) Side view of inflorescences, all at same magnification. (D) Ler. (E) hen2-1, note increased number of siliques and altered phyllotaxy (arrows). (F) hua1-1 hua2-1. (G) hen2-1 hua1-1 hua2-1, note reduction in internode length. (H) Ler inflorescence. (I) hen2-1 inflorescence, note the increased number of flowers and buds. (J) hen2-1 flower, note crowding of a lateral sepal with a medial sepal (arrows) and an extra petal (arrowhead). (K) hen2-1 hua1-1 flower, exhibiting an extra petal (arrowhead). (L) hen2-1 hua2-1 flower, note the short, apparently immature stamens. (M) Comparison of hen2-1 hua1-1 hua2-1 third whorl organs (five organs on the right), with sepal, petal and stamen from a hua1-1 hua2-1 flower. (N-S) Isolated gynoecia. (N) Ler. (O) hua1-1 hua2-1, note broadening at top of gynoecium. (P) hen2-1 hua1-1 hua2-1, gynoecium is small and bulging, with reduced stigmatic papillae. (Q) hen2-1, note lack of bulge. (R) hen2-1 hua1-1, the gynoecium bulges at the top. (S) hen2-1 hua2-1, note broadening at top.
