[Characteristics of the cytomixis in the pollen mother cells of transgenic tobacco plants (Nicotiana tabacum L.) with mutant phenotype].
This paper represents the frequency characteristics and cytological analysis of cytomixis in the course of male meiosis in transgenic tobacco plants (Nicotiana tabacum L.) with altered flower morphology and male sterility. The influence of cytomixis on qualitative composition of the meiotic products is shoron (cytoplasts and polyads formation). It was established that doubling of chromosomes number increased cytomixis frequency in the investigated plants.
