Graduate student, Julia Zheku, sectioned the wheat root radially using Leica VT1000S Vibratome and stained with calcofluor white (cyan) and propidium iodide (magenta). The image was captured with the Evident SpinSR microscope (UBC Bioimaging facility).

An an eukaryote, plant cells have nucleus. The nuclear shape is not constantly spherical. In this movie, you are watching nuclear shape (visualized by nuclear envelope protein; fluorescently tagged with green). on top of that you can see chromatin (magenta dots) inside the nucleus. Altogether, you will see dynamic nuclear shape and chromatin dynamics at the same time.

Tobacco pavement cell is differentiated cell, which means their fate is determined and these cells are not supposed to go through cell division. In this movie, the tobacco pavement cell is induced to go through mitosis and at the same time, nuclear envelope protein is expressed. As a result, we can observe the dynamic localization of nuclear envelope proteins during mitosis. 

An asymmetric cell division during the stomatal development. Microtubule and histone are visualized using CFP-TUB and YFP-HIS, respectively. 

During the asymmetric cell division, the division plane of future cell division goes wrong due to the misplacement of nucleus. Microtubule and histone are visualized using CFP-TUB and YFP-HIS, respectively.

Prior to the asymmetric cell division, nucleus is supposed to be polarized. In a nuclear envelope protein mutant, nucleus is moving away from the polarized side of the guard mother cell. 

Prior to the asymmetric cell division, nucleus is supposed to be polarized. In a nuclear envelope protein mutant, nucleus is moving back and forth to the polarized side of the guard mother cell. 

After the preprophase band formation, nucleus usually gets locked with the preprophase band. In a nuclear envelope protein mutant, nucleus is roaming around directionless even after the preprophase band formation.
