[Anomalies in cytoskeletal microtubules in a mutant line of sugar beets].
The morphological phenotype of meimutation acd (abnormal cytoskeleton dynamics) in Beta vulgaris was analysed using a classic method of achromatic figure visualization (Navashin fixative). The mutation demonstrates two different phenotypes under different growth conditions. The first variant is characterized by formation of chaotic network of microtubule bundles instead of two bipolar spindles at metaphase II. Such abnormality leads to the formation of polyads and monads. The second variant of phenotype demonstrates desorientation of spindles at metaphase II and partial asynapsis of homologous chromosomes.
