Figure 2. Interactions between RB-like CC domains from potato species with either IPI-O1 or IPI-O4.

The three-letter abbreviation for each species is shown. Numbers after the species name represents the PCR clone number. + and − signs to the right of the yeast colonies indicate positive or negative interaction, respectively. Photos were taken after 8 days of growth on selective media. Photos represent the results of three independent yeast transformations.
