Fig. 10. Cell expansion patterns and cell behavior at the boundary region. (A-C)
Reconstructed views of a SAM expressing 35S::YFP29-1, from a time series.
Total elapsed time is indicated in individual panels. Arrows point to the same
cells in the PZ over a period of time, and they divide along their long axis.
Arrowhead points to a cell in the CZ dividing along its short axis. The
white-boxed area in (B) represents the boundary region. Magnified view of a
time-lapse series of the boundary region is shown in (D-G). The total elapsed
time is marked on individual panels. Arrows indicate the same cells in the
boundary region across time. Arrowheads indicate adjacent cells in the
developing flower primordium. The lateral (L) and the medial (M) axis of the
developing flower primordium are marked in B. Scale bar: 20 µm in A-C; 10
µm in D-G.
