The mechanisms of plant cell dedifferentiation and the acquisition of totipotency are poorly understood. One of the methods to induce the dedifferentiation process in plant cells is simple and requires the removal of the cell wall. After cell wall removal in protoplasts, large-scale chromatin decondensation is observed (Tessadori et al. in J Cell Sci 120:1200–1208, 2007). Here, we show that...
The spatial organisation of the splicing system in plant cells containing either reticular (Allium cepa) or chromocentric (Lupinus luteus) nuclei was studied by immunolabelling of SR proteins, snRNA, and the PANA antigen, known markers for interchromatin granule clusters in mammalian cells. Electron microscope results allowed us to determine the distribution of these molecules within the structural...
