Abstract

C-banding studies revealed the presence of C-positive regions interspersed amongst the euchromatin of the prophase holocentric chromosomes of Luzula flaccida. In-situ hybridization showed a highly-repeated DNA sequence to be located in clusters throughout the extended chromosomes. The interspersed distribution pattern of prophase C-bands and satellite DNA in L. flaccida is discussed in relation to those in organisms with monocentric chromosomes.
