Research interests
Studies of wild populations and laboratory lines of model plant species, creating laboratory lines convenient for conducting experiments under controlled conditions, evaluating the effects of various environmental factors, such as UV and electromagnetic radiation, on growth parameters and the potential to generate point mutations at specific loci. Studies on genetic diversity, population genetic structure, phylogeny, phylogeography, effects of anthropogenic activities on wild populations, effects on nature and humans of fish (e.g. Rutilus rutilus, Perca fluviatilis).
Annotation of the doctoral dissertation
Purpose: To investigate the genetic structure of perch, roach and duckweed populations and possible effects caused by anthropogenic activities in Lithuanian and Latvian, using markers of nuclear coding genes, mtDNA D-loop fragments and chloroplast non-coding sequences and to determine the genetic variability in experimental clones of duckweed exposed of increased electromagnetic radiation using sequence markers of nuclear genes associated with oxidative stress.
Tasks: 1. To determine the markers of nuclear gene sequences for interpopulation and intrapopulation variability of perch and roach in Lithuania and Latvia.
2. To measure the genetic diversity of perch populations using markers of nuclear genes, mtDNA D-loop fragments, and microsatellite sequences.
3. To measure the genetic diversity of roach populations using markers of nuclear genes and mtDNA D-loop fragments.
4. To measure the genetic diversity of duckweed populations using markers of nuclear genes and chloroplast non-coding sequences.
5. To perform the comparative molecular studies of perch, roach and duckweed populations and to evaluate the possible effects of genetic structure caused by anthropogenic activities using genetic markers.
6. To determine the genetic variability in experimental clones of duckweed exposed of increased electromagnetic radiation using markers of nuclear genes and chloroplast non-coding sequences.
