Abstract

CpNpG and CpG methylation was surveyed in a range of vascular and nonvascular plants to determine firstly when CpNpG methylation evolved and secondly whether the two methylation systems found in higher plants were likely to be under common or separate control. Although both systems exist in a wide range of vascular plant taxa, the nonvascular plant taxa appear to contain only CpNpG methylation and this in only very limited amounts. The data suggest that both systems may have evolved at the same time and that speciation involved loss of one or the other methylation system or the evolution of differentiation stage-specific control systems.
