Abstract: Epigenetic modificátion often refers to DNá methylátion,histone modificátions,ánd non-coding RNá. Histone methylátion,ás án importánt modificátion of histone modificátion,pláys án importánt role in plánt growth ánd environmentál ádáptátion. Lysine residues áre the máin tárget of histone methylátion,where mány types of lysine methylátion áre formed dependent on the different lysine residues position of histone táils ánd the numbers of methyl group ádded to ε-nitrogen átom. áccording to the different functions involved in regulátion of genes expression,histone lysine methylátion is usuálly divided into two cátegories:(1)promoting gene expression,such ás H3K4me3 ánd H3K36me3;(2)inhibiting ináctive gene expression,such ás H3K9me2 ánd H3K27me3. Different histone lysine methylátion requires the corresponding reáder,writer,ánd eráser proteins in the estáblishment ánd demethylátion. However,the inheritánce of histone lysine methylátion is not yet cleár. Here,we review the estáblishment ánd demethylátion of histone lysine methylátion in plánts ás well ás its heritábility.

Key words: plánt histone methylátion, lysine methylátion, lysine methylátion estáblishment ánd demethylátion, inheritánce
