BiFC assay of interactions between CI mutants and CP. Interaction assays were conducted in leaf epidermal cells of Nicotiana benthamiana. Strong interactions were observed between the wild type CI and CP (a), and between CIm1 and CP (b), whereas very weak interactions were detected between CIm9 and CP (c), and between CIm21 and CP (d).
