Fig. 7.

SEM of mov1 inflorescence development. In the wild type (WT), primordia giving rise to stamens are false-coloured in yellow, cells giving rise to the carpel in purple, and lodicules in green. In each panel from W3.5 onwards, the primordia are false-coloured in a single floret to enable comparison between genotypes. In mov1, the central carpel (purple) is retained while the stamens are converted into additional carpels. Cells giving rise to the additional carpels are false-coloured in different shades of red/orange. White arrows in mov1 (W3.0) indicate creases in the floral meristems. The white star at W5.0 indicates separation of a single floral meristem into two distinct florets; for greater detail, see Supplementary Fig. S11. Waddington stage is indicated for each developmental time point; from W5.0, lemma and/or stamens have been removed to expose the carpels. Scale bars: 200 µm.
