Key directions of scientific research:

  • Study of genome polymorphism as a basis of biotechnology;
  • Study of the role of DNA methylation processes in the regulation of gene expression;
  • Identification of molecular genetic mechanisms of plant adaptation to abiotic and biotic stresses;
  • Study of the genetic diversity of plants, fish, and honey bees;
  • Development of new DNA technologies for the marker-assisted selection of new varieties of agricultural plants, fish breeds, races of honey bees and their genetic certification;
  • Development of methods for molecular genetic diagnostics of a predisposition to hereditary diseases in companion animals;
  • Development of technologies for genetic identification of fish and seafood.
