WebChromomethyltransferase CMT2, along with DMT DRM2, is responsible for methylation of CNN sites in the Arabidopsis genome [7]. On the phylogenetic tree of chromomethylases, methyltransferase CMT2 forms a separate branch. In most organs, the CMT2 gene is expressed much more weakly than CMT3. WebJan 9, 2024 · CHG and CHH methylation in heterochromatin are maintained by CHROMOMETHYLTRANSFERASE 2 (CMT2) and CMT3, respectively (Stroud et al. 2014; Zemach et al. 2013 ). In addition to CMT2, DRM2 is also likely involved in the maintenance of CHH methylation via the RdDM pathway (Zhang et al. 2024 ).
