RNA gel-blot analysis. Total RNA was extracted from endosperm of kernels harvested at 20 DAP, fractionated on a 1% (w/v) agarose-formaldehyde gel, and hybridized with Su1 cDNA antisense RNA. RNA concentration variations can be visualized by the ethidium bromide-stained rRNA, shown in the lower panel. The lanes shown were run simultaneously in the same gel.
