Origin of an apparent B chromosome by mutation, chromosome fragmentation and specific DNA sequence amplification.

Chromosoma - 1 Dec 2002

Dhar Manoj K, Friebe Bernd, Koul Awtar K, Gill Bikram S

Abstract excerpt

The present study documents the de novo origin of an apparent B chromosome in Plantago lagopus. The origin was associated with mutation (aneuploidy), chromosome fragmentation, specific DNA sequence amplification, addition of telomeric repeats, and centromeric misdivision. It originated in the progeny of trisome 2, from the excision of 5S rDNA and 18S, 5.8S, 25S rDNA sequences located on chromosome 2, and within a...
