[Disruption of male meiosis in transgenic line tobacco res91].
The course of meiosis in male-sterile trasgenic tobacco line res91 has been analysed. Cytological analysis included visualization of the spindle and phragmoplast. Abnormal meiosis was characterized with 1) cytomixis; 2) deformation of nuclei at prophase 2 in part of the cells, and lack of spindle formation in such cells at M2; 3) desorientation of spindles in meiosis 2. This set of abnormalities allows to suppose certain disturbancies of cytoskeleton during male meiosis in res91.
