[Dynamics of cytoskeleton microtubules in higher plant meiosis. I. The perinuclear band of microtubules and the meiotic spindle formation].
A planar meridional perinuclear band of microtubules was observed at the late meiotic prophase I in a range of higher plant species. A distinct high-organized structure and a long time of existence allow to consider it as a new class of MTs dependent on the cell cycle in plant meiosis. MTs of the perinuclear band convert into meiotic spindle through a complex process of spatial rearrangements.
