Figure 2.

Patterns of axillary inflorescence development in the rosette leaves after bolting. R1–R7 represent rosette leaves 1–7. R1 is the oldest rosette leaf. Cot represents a cotyledon. (A–C) Wild-type axillary buds in the axils of rosette leaves: R7 (A), R5 (B), and R3 (C). (D–F) sps axillary buds in the axils of rosette leaves: R7 (D), R3 (E), and R1 (F). The photographs were taken at the same magnification for the comparison. Arrows indicate the developing axillary inflorescence. (G) Diagrammatic representation of the axillary buds developing in each leaf axil and shown as dotted bars. Relative sizes of the axillary buds are shown as relative sizes of bars. Eight plants from wild type and an sps mutant allele (see text) were used for the analysis. As all of the wild-type plants show a similar pattern of axillary inflorescence development, a representative wild-type plant is shown here (wt), whereas eight individual sps plants are shown (sps: 1–8).
