Subcellular localization of AtPum proteins. Representative epifluorescence images of cells expressing AtPum proteins fused to the amino terminus of GFP or RFP in onion (A to D) or fava bean (E to I) epidermal cells. (A) AtPum7-GFP, (B) AtPum8-RFP, (C) AtPum9-RFP, (D) AtPum10-GFP, (E) AtPum12-GFP, (F) AtPum14-GFP, (G) AtPum18-RFP, (H) AtPum23-GFP, and (I) AtPum24-GFP. Arrow identifies heavily stained region that likely resulted from aggregation of protein complexes. Bar, 10 microns.
