Phenotypic assays of the RNAi transformants on 5-FOA plates.

<p><i>URA3</i>-silenced transformants, wild-type (<i>wt</i>) and control transformants (CK1, transformed with plasmid pAN7-1) were cultured on CYM medium containing 600 µg/mL 5-FOA for ten days. Hp-2 was one of the pAN7-ura3-hp transformants, s-13 was one of the pAN7-ura3-s transformants, as-3 was one of the pAN7-ura3-as transformants, and dual-2 was one of the pAN7-ura3-dual transformants.
