when plastid dnas from the original and green cell lines were digested with methyl-sensitive restriction enzymes , dna methylation was detected in regions containing the genes for the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase ( rbcl ) , subunits of chloroplast coupling factor 1 ( atpa , -b , and -e ) , the apoprotein of p700 ( psaa ) , and ribosomal protein s4 ( rps4 ) but not the genes for 16s rrna and the 32-kda qb protein ( psba ) in the original line , whereas no methylation was observed in the green line .
