Abstract excerpt

An Eco RI polymorphism, present in the 26S ribosomal RNA gene (rDNA) of the maize hybrid Sx19 (B73 x Mo17), was utilized to correlate DNaseI sensitivity, undermethylation and expression in rDNA. We have previously shown that in double digest experiments with methylation-sensitive restriction enzy...
