Wheat root tips in seven stages of the cell cycle. 7-aminoactinomycin D.

Panel of confocal micrographs showing cells from wheat root tips in seven stages of the cell cycle. DNA was stained with 7-aminoactinomycin D (A1310]), and microtubules were labeled with an anti&endash;ß-tubulin antibody in conjunction with a fluorescein-labeled secondary antibody. Cells vary in width from about 15 µm to about 25 µm. The stages are (from top left): interphase cortical microtubule array; pre-prophase band of microtubules (predicts future plane of division); metaphase mitotic spindle; telophase, showing early phragmoplast and cell plate; fully developed phragmoplast during cytokinesis; late cytokinesis (plane of division matching plane of earlier pre-prophase band); restoration of cortical arrays in daughter cells.
