Total RNAs from various sources were hybridized with probe EE2.3. The RNAs as they appeared in the ethidium bromide (EtBr)-stained gel before transfer are shown to indicate RNA integrity and loading differences. A, RNAs from embryo (Em) and endosperm (En) harvested 20 DAP, seedling leaves (L), immature root (R), and immature tassel (T). B, RNAs from maize endosperm harvested at various times after pollination. C, RNAs from nonmutant (Su1) and mutant (su1-Ref ) kernels harvested 20 DAP.
