Nuclear phenotypes of crwn mutants. Images of representative DAPI-stained adult leaf cell nuclei from wild type and the twelve viable crwn mutants. The top row contains the wild type control and crwn2, crwn3 and crwn2 crwn3 mutants with normal nuclear morphology phenotypes. The middle row shows nuclear phenotypes of crwn1 and double mutants containing a crwn1 mutation. The bottom row displays nuclear phenotypes from crwn4 mutants, as well as higher-order mutants containing a crwn4 mutation. The arrowheads highlight thin projections from crwn4 nuclei. A 5 μm size bar is shown in the upper left inset; all images are shown at the same magnification.
