FIG. 1.

Agarose gel electrophoresis of total leaf RNA extracts from plants infected with CNV transmission mutants. N. clevelandii plants were inoculated with equal amounts of WT CNV or the indicated mutant virions, and total RNA was extracted from inoculated leaves 3 dpi. Equal amounts of total RNA were loaded onto a nondenaturing 1% agarose gel. The gel was stained with ethidium bromide.
