Laboratory of Plant Cytogenomics

Head: Elena A. Sycheva

PhD (Biology), Associate Professor


Key directions of scientific research:

  • Cytogenomics of grain crops, studying the structural and functional variability of genomes at molecular and cellular levels at distant hybridization, polyploidy and inbreeding;
  • Studying of microevolutionary differentiation mechanisms of polyploid crop species;
  • Experimental transformation of the genetic structure of cereal crops (rye, wheat, triticale, and secalotriticum) by chromosome engineering methods;
  • Chromosomal and molecular marking of the new gene pool of tetraploid and hybrid (CMS) rye, recombinant tetraploid and hexaploid forms of triticale and secalotriticum; marker-assisted selection (MAS).
