The drm1 drm2 cmt3 triple mutant plants did not affect CpG methylation at any locus tested, suggesting that the WebMar 20, 2009 · CHG methylation is maintained by the plant-specific CHROMOMETHYLASE 3 (CMT3), and KRYPTONITE (SUVH4), a histone protein methyltransferase. CMT3 binds to methylated histones (chromatin-associated proteins) and KRYPTONITE binds to methylated CHG sites, thereby creating a feedforward loop for …
