Laboratory of Cellular and Molecular Protistology

Staff Gallery

Laboratory of Cellular and Molecular Protistology was founded at the end of 2018. Main direction of its activity is evolutionary and taxonomic studies of the key phylogenetic clades of unicellular eukaryotes, research on species problem, biogeography, and the role of protists in natural communities. The research of the Laboratory combines both classical approaches that are based on the studies of morphology and physiology of protistan cells as independent organisms, and modern techniques of phylogenetics, phylogenomics, and molecular biology.

At present, the Laboratory staff is accumulating data on the patterns of the geographic distribution of the key taxa of amoeboid protists, and have collected data for taxonomic revision and reconstruction of the cell coat evolution of amoebae from the order Dactylopodida (Amoebozoa). The research is performed on the biodiversity of Foraminifera in the Arctic seas of Russia, lifecycles of Heliozoa, symbiotic systems of ciliates with prokaryotes, and molecular evolution of trypanosomatid flagellates. In addition, the staff of the Laboratory studies the origin and early evolution of multicellular opisthokonts based on genomic and transcriptomic data analysis.
