Research conducted in the Department of Biotechnology takes advantage of plant biotechnology methods, including: DNA recombination, transformation and analyses of transgenic plants, in vitro cultures, molecular and protein markers as well as rheological analyses.
Research carried out by the Bioengineering Team concentrates on plant production of biopharmaceuticals, for the most part vaccines administered by oral and/or injection route. The main topic is a preventive vaccine against Hepatitis B Virus (HBV), but also other vaccines are worked on, as a vaccine for therapy of chronic hepatitis B or an anti-HBV/HIV bivalent vaccine. The third field of team?s activity is utilisation of some multimeric proteins as carriers for various immunogenic epitopes.
Studies carried out by the Cereal Phenotyping and Genotyping Team focus on molecular basics of phenotypic variation of agronomic traits in wheat and barley. Materials for the studies consist of doubled haploid and RIL populations, for which genetic maps based on molecular markers are constructed. Plants are phenotyped under fields and controlled greenhouse conditions. Quantitative and qualitative traits of significant importance for agriculture are analysed; special attention is paid to yield, technological and rheological parameters of  grain quality, and properties associated with the resistance to biotic and abiotic stresses. Varietal identity and biodiversity of cereal crops are assessed using electrophoretic, chromatographic and molecular methods. Besides, pleiotropic effects of major genes are examined at the whole plant, organ and tissue levels.
