Methylated and undermethylated rDNA repeats are interspersed at random in two higher plant species.
The organization of methylated rDNA repeats of radish and pea is described and it is shown that methylated repeats and non-methylated repeats are interspersed one with another. Methylated arrays are not much longer than 100 kb, or about 10 repeat units in length.
