A model explaining the observed changes in the expression level of cell cycle related genes during the floral transition of the shoot apical meristem (SAM). At stages before M4 cells cycle slowly due to long G1 and G2 phases. There is also a large proportion of non-cycling (G0) cells. During floral transition (M4 to M5), the cell cycle duration is shortened at the expense of the G1 and G2 phases, and many G0-arrested cells enter the cell cycle. Subsequently, (after M6), the duration of the cycle increases again. Typical expression patterns of cell cycle regulated genes are shown schematically in the lower panel (those for mitotic genes are red, for S-phase specific genes are dark blue, and G1/G2 and G0 genes are green and yellow, respectively)
