Mutation of the woolly motif attenuates the interaction between Nbwo and NbCycB2 in N. benthamiana. (a) Yeast two-hybrid (Y2H) assays of the interactions between NbCycB2 and Nbwo or NbWoV using QDO/X/A medium. Clones with pGADT7-53 (BD-53) and pGADT7-T (AD-T) served as positive controls, and clones with pGBKT7-Lam (BD-Lam) and pGADT7-T (AD-T) served as negative controls. Only the positive control and AD-Nbwo and BD-NbcycB2 could grow on the medium. (b) Pull-down assays between Nbwo or NbWoV with NbCycB2 proteins. The NbCycB2-GST protein was immunoprecipitated with glutathione agarose, and the immunoblots were probed with anti-HIS and anti-GST antibodies. Only the recombinant HIS-Nbwo protein could co-precipitate with GST-NbCycB2. The asterisks indicate the bands for Nbwo or NbWoV. (c) Y3H assays to determine the competition between NbCycB2 and the LZ domain of Nbwo for binding to Nbwo (fused to GAL4 DNA-AD). The methionine-repressible promoter in the pBridge vector controlled the expression of NbCycB2 in the presence of the Nbwo LZ domain (fused to GAL4 DNA-BD). (d) Pull-down assays to determine whether NbCycB2 could compete for binding to Nbwo. The total protein from P35S::HA-Nbwo protoplasts was immunoprecipitated with anti-HA beads, and the immunoblots were probed with anti-Flag and anti-MBP antibodies.
