Chromosomal position effects reveal different cis-acting requirements for rDNA transcription and sex chromosome pairing in Drosophila melanogaster.

Genetics - 1 Jul 2000

Briscoe A, Tomkiel J E

Abstract excerpt

In Drosophila melanogaster, the rDNA loci function in ribosome biogenesis and nucleolar formation and also as sex chromosome pairing sites in male meiosis. These activities are not dependent on the heterochromatic location of the rDNA, because euchromatic transgenes are competent to form nucleoli and restore pairing to rDNA-deficient X chromosomes. These transgene studies, however, do not address requirements for...
