• Supplemental Figure 1 -

  Fig. S1. Photograph of the tool used to determine phyllotactic pattern. (A) Fully grown stems were fixed with the apex pointing down in the centre of the structure. The central part of the device was gradually slid down to measure parameters for successive organs. Divergence angles and internode lengths were measured with precisions of 10 degrees and 0.5 mm, respectively. (B) Divergence angle was measured between the insertion point of the pedicel of two successive siliques (top). This measure does not depend on the orientation of the pedicel outgrowth (bottom).

• Supplemental Figure 2 -

  Fig. S2. Phyllotactic pattern and meristematic phyllotaxy of wild-type and CUC2g-m4 plants (Col background). Correlation between divergence angles and internode lengths of successive organs along fully grown wild-type inflorescence stems is shown. Distribution of the divergence angle between two successive flowers along the stem. Percentages of divergence angles (n) falling into twelve 30° classes and average (av) are shown. Distribution of internode length between two successive flowers along the stem. Percentages of internode lengths measured falling into classes of 3 mm are represented.

• Supplemental Figure 3 -

  Fig. S3. Correlation between divergence angles and internode lengths of successive organs along fully grown wild-type inflorescence stems. The sizes of the dots indicate the number of measurements made.

• Supplemental Figure 4 -

  Fig. S4. Phyllotactic pattern in the inflorescence stems of wild-type plants grown under different conditions. (A) Plant grown during the summer (2005) in a greenhouse with partial temperature control and no protection against the sun, with fertiliser treatment. (B) Plant grown during the summer (2005) in a greenhouse with partial temperature control and protection against the sun, with fertiliser treatment. (C) Plant grown during the summer (2005) in a greenhouse with partial temperature control and protection against the sun, with no fertiliser treatment. (1) Distribution of the divergence angle between two successive flowers along the stem. Percentages of divergence angles (n) falling into twelve 30° classes are shown. (2) Distribution of internode length between two successive flowers along the stem. Percentages of internode lengths measured falling into classes of 3 mm are represented. Insets show a finer distribution for internodes less than 3 mm long, in classes of 0.5 mm. Note that the scale is different for the G 3 graph.
