| Abstract: | Using various restriction endonucleases, methylation of nuclearribosomal RNA genes (rDNA) was investigated. Results indicatethat cytosine residues of C-G dinucleotides of Nicotiana glaucarDNA are heavily methylated. 1This work was supported in part by a grant from the ScienceResearch Fund of the Ministry of Education, Science and Cultureof Japan.
