Barley RIPa interacts with barley type I and type II ROPs in yeast. Bait- and prey-construct transformed yeast cells were dropped on either transformation-selected (SD -L-W) or interaction-selective (SD –L,-W,-A-H) medium. pGADT7 and pGBKT7 present empty vector controls to exclude auto-activity of respective ROP or RIPa constructs
