Figure 1. DNA methylation in methylation-sensitive loci detected from all analyzed specimens of Xenostrobus securis, per population.

Type I to IV are respectively: no methylated, methylation of internal C, methylation of external C or hemimethylation, and hypermethylation or mutation in restriction site. Methylated: Global methylation level estimated following Nicotra et al. (Nicotra et al.⁴¹), as proportion of (Type II+Type III loci)/(scorable loci). The letters yo mean “year old”.
