The number of transcriptionally active nucleolar organizer regions (NORs) of one monohaploid, one dihaploid and two tetraploids of Solanum tuberosum and one diploid S. phureja was established by the silver staining of metaphases in root meristems and in in vitro-cultured leaf explants. The maximum number of active NORs per cell was one per haploid set of… CONTINUE READING
