Arabidopsis SWP73A and B Interact with Core SWI3 Subunits of SWI/SNF Complexes.

(A) Yeast two-hybrid assays showing SWP73-SWI3 protein interactions (blue color). Right panel: controls for the yeast two-hybrid protein interaction assays.

(B) BiFC assays of in vivo interactions of SWP73B, SWI3C, and SWI3D proteins in wild tobacco (Nicotiana benthamiana) leaves. Left panel, YFP channel; middle panel, differential interference contrast image; right panel, merged picture. Lower panels: Negative controls for BiFC analysis including the RFP channel. Bar = 10 µm.

(C) Model of interaction network between SWP73A, SWP73B, and core subunits of SWI/SNF complex. Red lines indicate data presented in this article. Black lines indicate previously published data (Sarnowski et al., 2005; Vercruyssen et al., 2014).
