Figure 5. Northern-blot analysis of GH5BG transcript levels in (A) 7-day-old rice seedlings and 6-week-old mature plant tissues and (B) 7-day-old rice seedlings grown a further 2 days with various abiotic stresses and plant hormones.

GH5BG, RNA blots were probed with α-³²P-labelled GH5BG gene-specific probe; 18S rRNA indicates the same blot probed with an α-³²P-labelled 18 S rRNA cDNA probe. A 20 μg portion of total RNA from the appropriate tissues was loaded in each lane.
