Research profile

The aim of team’s research is to use biotechnological methods together with natural plant traits for utilitarian purposes. The research are conducted in two fields of plant biotechnology: biopharming and the use of giant grasses of Miscanthus genus for bioenergy and phytoremediation. The first one includes production of antigenic proteins assembled into Virus-Like Particles (VLPs) in plant expression systems and their use as vaccines and epitope and nanoparticle carriers. The second area involves the determination of biological mechanisms responsible for Miscanthus tolerance to abiotic stresses such as cold and arsenic soil contamination. It also investigates their effects on biomass production. These mechanisms, along with supporting biotechnological methods, are being explored to enhance the production of bioethanol, other biofuels and bioproducts and soil phytoremediation.

We use methods common for both research fields as tissue cultures and statistical analysis together with bioinformatics as well as specific methods. Production and processing of VLPs includes: DNA recombination, plant transformation using Agrobacterium tumefaciens and biolistic method, plant in vitro regeneration, transient expression, transgene detection, protein assay/detection using ELISA and western blot, protein purification or plant tissue lyophilisation and finally analysis of elements of immune response. Complex studies of Miscanthus reaction to stresses are performed using spectrum of methods: gene transcription using qPCR and whole transcriptome analysis, enzyme activity assay, measurements of photosynthesis and other physiological processes, biochemical and metabolic analyses, micropropagation and phenotyping, bioethanol production.

Our main achievements in biopharming are: production of VLPs assembled by HBcAg and S-HBsAg (core and small surface antigens of Hepatitis B Virus) in plant expression systems, development of basics of processing of plant material to obtain vaccine preparations, determination of conditions of effective injection-oral immunization using plant-derived vaccines.

Studies in the area of Miscanthus exploitation for bioenergy/phytoremediation resulted so far in: development of effective regeneration and biolistic transformation system, determination of Miscanthus as a feedstock for bioethanol production, recognition of fundamental mechanisms of cold tolerance of Miscanthus and its effects for cell wall reconstruction, determination of basics of arsenic tolerance, effects of the stresses for biomass quantity/quality and bioethanol production.
