Fig. 1. Phyllotactic pattern in CUC2g-m4 and wild type. (A) Axillary region. An additional leaf develops in the axils of CUC2g-m4 plants (arrow). (B) Frequency of the extra leaf phenotype in independent transgenic lines. (C) Strong CUC2g-m4 plants with an extreme reduction of the inflorescence (arrow) and of flowers with long pedicels (arrowhead). (D) Inflorescence of wild-type and representative CUC2g-m4 plants showing an abnormal phyllotactic pattern. (E) Close-up of D. (F) Detailed analysis of the phyllotactic pattern in wild-type and CUC2g-m4 plants (WS background, see Fig. S2 in the supplementary material for Col). Left: distribution of divergence angle between two successive flowers along the stem. Percentages of total divergence angles measured (n) that fell into 12 classes, each of 30°, and the averages (av) are shown. Right: distribution of internode length between two successive flowers along the stem. Percentages of total internode lengths that fell into classes of 3 mm each are shown. Insets show a finer distribution of internodes that were less than 3 mm long, in classes of 0.5 mm. Notice that the scale is different for the insets.
