Multi-chromosomal location of ribosomal RNA genes and heterochromatin association in brown trout.

A M Pendás1, P Morán, E Garciía-Vázquez.   

Abstract

The ribosomal rRNA genes have been mapped by fluorescent in situ hybridization (FISH) to brown trout chromosomes. One major NOR chromosome pair and 8 novel minor NOR chromosome pairs have been found. Both major and minor NORs were closely related to polymorphic heterochromatin, as revealed by FISH and C-banding. These results are discussed with respect to NOR expression, the relationship between rDNA and heterochromatin, and evolutionary aspects.
