Fig. 4From: Molecular cloning, expression analysis and subcellular localization of four DELLA genes from hybrid poplarSubcelluar localization of the Populus DELLA proteins. Green fluorescence protein (GFP), chlorophyll autofluorescence (Auto), merged 1, bright and merged 2 images are shown. Scale bar 5 µm. The 35::GFP fusion was used as a positive protein control, and was detected in the nucleus and cytoplasm in protoplastsBack to article page
