✦ Synopsis

An electron microscope study has been made of the generative cell in Endymion non-scripta. At interphase microtubules are found in bundles against the cell wall, aligned with the long axis of the cell. These microtubules are frequently cross-linked. Mitotic spindle microtubules at prophase show no cross-linking. The implications of this result for a proposed model for mitosis are discussed.

The assembly of the higher plant cytoskeleton poses several fundamental questions. Since different microtubule arrays are successively assembled during the cell cycle in the absence of centrosomes, we can ask how these arrays are assembled and spatially organized. Two hypotheses are under debate. Ei
