Subcellular localization of four GFP-fused VvBBX proteins. The four VvBBX-GFP fusion proteins (VvBBX1-GFP, VvBBX9-GFP, VvBBX13-GFP and VvBBX22-GFP) were transiently expressed in tobacco leaves and observed by fluorescence microscopy 72 h later. Nucleus were visualized by co-transformation with an mCherry-labelled nuclear marker ((NF-YA4-mCherry)
