In situ hybridization of rice root apices with
probes specific for transcripts of cdc2Os1,
cdc2Os2, cdc2Os3, and R2.
Longitudinal sections of roots were allowed to hybridize with
digoxigenin-labeled RNA probes. Hybridization signals are visible as
brownish-purple staining. a, cdc2Os1 antisense probe; b,
cdc2Os2 antisense probe; c, cdc2Os3
antisense probe; d, R2 antisense probe; and e,
cdc2Os1 sense probe. Bar = 100 μm.
