Abstract

The migration of chromatin between cells in microsporogenesis in Cerasus fruticosa Pall occurs through plasmodesma or by cell fusion. Cytomixis is detected in 13.0% of anthers. Cytomixis often occurs at the earliest stages of chromosome condensation in prophase I (leptonema, zigonema) and develops as a full cell fusion. This anomaly begins with the formation of 1 - 3 cytoplasmic canals between meiocytes. Then the canals begin to increase in size. Both cells unite. The cytomixis consequences occur at different stages. At the meiosis final stages the chromatin that migrates into the recipient cell is defined as micronuclei or cytomixis polyads.
