SUVH4, SUVH5, and SUVH6 Interact with HDA6.
BiFC assays of Arabidopsis protoplasts showing that SUVH4, SUVH5, and SUVH6 interact with HDA6. SUVH4/5/6 and HDA6 fused with the N terminus (YN) or the C terminus (YC) of YFP were cotransfected into protoplasts and visualized by confocal microscopy. Hoechst staining indicates the nucleus. DIC, differential interference contrast.
