Localization of AtCPSF30 in cells that also express AtCPSF160. GFP-AtCPSF160 was co-expressed with DSRed2-AtZFP11 (panels A-C) or DSRed2-AtCPSF30 (panels D-O). The column labeled "CPSF160" denotes the images of the GFP-AtCPSF160 fusion protein, and the column labeled "marker" denotes either the DSRed2-AtZFP11 marker (panel A), DSRed2-AtCPSF30 (panels D, G, and J), or Hoechst stain (panel M). Panels K and N are the same sample; panel M shows the results of Hoechst staining of the cell shown in Panels J-O, and panel O is the overlay of panels M and N. Multiple cells expressing both AtCPSF30 and AtCPSF160 are shown, as are different scales, to illustrate the variations that were observed in these studies. Red bars in the overlay panels are 10 μm size markers.
