Figure 1.

Northern-blot analysis of total RNA isolated from beechnut seeds imbibed at 4°C in 100 mm ABA, water, and 100 mm GA₃ from 1 to 6 weeks. Ten micrograms of RNA were used per lane and hybridized with a FsGASA4 cDNA probe. Top section: Ethidium bromide-stained gel showing RNAs. The numbers indicate weeks of imbibition.
