...Lara Spinner; Martine Pastuglia; Katia Belcram; Mathieu Pegoraro; Magali Goussot; David Bouchez; Didier G. Schaefer The preprophase band (PPB) is a transient ring of microtubules that forms before mitosis in land plants, and delineates the cytokinetic division plane established at telophase...

... are required for nuclear/MtOC rotation. These inhibitors also result in aberrant orientation of the first division plane. Microtubules visualized by confocal microscopy connect the rotating nucleus to the apical cortex and may provide the force for rotation. In experiments utilizing cold treatment...

... expected. These results suggest that cell interactions immediately prior to and during division do not influence strongly the orientation and position of the division plane. In contrast, interactions between the cells within an intact early 8-cell embryo, which is subsequently disaggregated to singletons...
