Physical mapping of ribosomal DNA sites in Festuca arundinacea and related species by in situ hybridization.

Abstract

UNLABELLED: The positions of the 18S-5.8S-26S and 5S rRNA genes have been physically mapped on the chromosomes of diploid, tetraploid, and hexaploid Festuca species by in situ hybridization. The number and position of the rDNA sites in the species were compared. The results confirm some of the earlier phylogenetic studies of these species but suggest that some structural rearrangements have occurred and that sites have been lost during polyploidization. KEYWORDS: Festuca, in situ hybridization, phylogeny, physical mapping, rDNA.
