Endoreplication phenotypes of the ccs52a1-1 DEL1OE double mutant. A, Flow cytometric analysis of wild-type (Col-0), ccs52a1-1, DEL1OE, and ccs52a1-1 DEL1OE three-week-old first true leaves. Data are representative for the mean (n = 3). B, Scanning electron microscope images of wild-type (Col-0), ccs52a1-1, DEL1OE, and ccs52a1-1 DEL1OE trichomes. Images are representative for the mean (n = 3). Bars = 300 μm. C, Epifluorescence images of DAPI-stained wild-type, ccs52a1-1, DEL1OE, and ccs52a1-1 DEL1OE trichome nuclei. Images are representative for the mean (n > 13). Bars = 10 μm.
