The actin cytoskeletal characteristics of the root meristem cells in Beta vulgaris L. at different mitotic stages

For the first time the actin cytoskeleton in meristem cells of B. vulgaris root has been studied. It was established that all discovered earlier patterns of microfilament arrangement were also specific for meristem of present species. Specific rearrangements of actin in the sites of spindle (prophase) and phragmoplast formation (telophase) were revealed. It is supposed, that actin cytoskeleton determines certain position of spindle in cells and takes part in the cell plate formation.
