Single integration and spread of a Copia-like sequence nested in rDNA intergenic spacers of Allium cernuum (Alliaceae).

Cytogenetic and genome research - 1 Jul 2010

Chester M, Sykorova E, Fajkus J, Leitch A R

Abstract excerpt

The 35S ribosomal DNA (rDNA) intergenic spacer (IGS) of Allium cernuum is examined. Initial sequencing of IGS clones revealed that some rDNA units contain a truncated retrotransposon sequence most similar to members of the Copia superfamily. Fluorescence in situ hybridisation (FISH) to metaphase chromosomes indicates that this element is dispersed along both pairs of major rDNA arrays. Southern hybridisation...
