The influence of 5-azacitidine (5A) DNA-demethylation agent on Amur grapes (Vitis amurensis Rupr) cellular culture with the help of karyological indicators is described in the article. The chromosomal variability increase and the kernel relation reduction as the result of 5A processing in various studied culture concentrations are determined. These processes testify the cells protein biosynthesis activation.
