Fig. 2. Cytokinesis defects in elc mutants. The nuclear phenotypes of wild type and elc were shown by DAPI staining. (A) Wild-type trichome with one nucleus located at the branch point. (B-F) elc mutant trichomes with two nuclei in one stem (B), one nucleus in each stem (C), with three nuclei (D) and with four nuclei (E). (F) Higher magnification of E. (G) Occasionally, trichomes with a wild-type appearance have two nuclei. (H) Multiple nuclei in epidermal pavement cells. (I) Multiple nuclei in hypocotyl cells. (J) Incomplete cell wall in an epidermal pavement cell (red arrow). (K) DAPI staining of J to indicate the position of the two nuclei in the cell (black arrows); the white arrow marks the incomplete cell wall.
