Nucleogenesis during microsporogenesis of Rheo discolor

The present paper deals with the study of Nucleogenesis and nucleolar behavior during microsporogenesis of Rheo discolor using silver- nucleolar organizer regions (NOR) staining technique. It is observed that only one nucleolar organizer regions is present in each genome of R. discolor and NORs are achieved during the Pre-meiotic and meiotic stages. It is observed that common pattern of nucleolar activity is not conserved in the present plants and process of nucleogenesis is similar in both mitotic and meiotic cell divisions
