Extensive Natural Epigenetic Variation at a De Novo Originated Gene
Figure 1
QQS is embedded in a repeat-rich region.
(A) Genomic structure of the QQS locus (30 kb window) in the Col-0 accession. Dark grey boxes represent two additional TE sequences predicted by [51], [52]. (B) Magnified view of the QQS gene and upstream sequences, showing tandem repeats (TR), methylation of cytosine residues (5 mC) at the three types of sites (CG, CHG and CHH, H = A, T or C) and locus-specific sense and antisense siRNAs (numbers referring to copy number). DNA methylation and siRNA data are from [25].
