Relationship between genomic organization and DNA methylation of 5 S genes in the studied species
Species 1Organization Number of 5 S loci 1Position on chromosomes 2mC average mC range
Artemisia absinthium LS 2 (sub-)terminal 46% 34-62%
Tagetes patula L 7 (sub-)terminal 33% 11-44%
Elachanthemum intricatum SL n.d. n. d. 39% 31-45%
Helichrysum bracteatum L 1 (sub-)terminal 34% 16-43%
Helianthus annuus S 5 pericentromeric 63% 30-96%
Arabidopsis thaliana S 3 pericentromeric 379% 336-95%

1 The genomic organization and chromosomal position of 5 S rDNA is taken from [12-15,38] and from the Plant rDNA database [39].

2This work.

3 Methylation levels of coding region were determined by bisulfite sequencing. Data for Arabidopsis genes are from [40]; slightly lower values were reported in [41].
