Correlation between the size of the intergenic regulatory region, the status of cytosine methylation of rRNA genes and nucleolar expression in wheat.

Molecular & general genetics : MGG - 1 Jan 1993

Sardana R, O'Dell M, Flavell R

Abstract excerpt

A large number of wheat rRNA genes are methylated at all the CCGG sites that are present in the intergenic regions. A smaller number of rRNA genes are not methylated at one or more CCGG sites. A subset of genes was found unmethylated at a specific CCGG site just downstream of the array of 135 bp A repeats in the intergenic region. In all the genotypes studied, the rDNA loci with larger intergenic regions between...
