Figure 2.

In situ hybridization of cross-sections of rice roots with probes specific for transcripts of cdc2Os1 and cdc2Os3. Cross-sections were prepared from each part of the root, as shown schematically by red shading in the region of dividing cells in the drawing on the left. Numbers indicate positions from which sections were prepared. Pc, Pericycle; Qc, quiescent center; Rc, root cap; Sc, sclerenchyma; Xy, xylem. a, cdc2Os1 antisense probe; b, cdc2Os3 antisense probe; and c, cdc2Os1 sense probe. Bar = 100 μm.
