Localization of the Transcripts of NtmybA1, A2, and B in Tobacco Shoot Apices.
Longitudinal sections of shoot apices were hybridized with digoxigenin-labeled antisense RNA probes of Nicta;CycB1;3 (CycB) and NtmybA1, A2, and B and viewed under a bright field. Hybridization signals are visible as purple color development. Sense RNA probes did not produce any hybridization signals (data not shown). Bar = 50 μm.
