Main research directions


  • Development of new, fast and specific methods for the detection of plant viruses.
  • Studying the occurrence of plant viruses, host range, symptoms on plants caused by viral diseases.
  • Identification of potential determinants in the genome of viruses responsible for the occurrence of specific symptoms in plants.
  • Analysis of genetic diversity and evolutionary dynamics of viruses (recombination and reassortment, rate of replication, co-evolution of amino acids, selection pressure affecting individual codons, determination of phylogenetic relations between isolates, correlation between the position of the isolate on the tree and the origin of the virus and its host).
  • Studying the dRNA formation process depending on the number of subcultures, virus species and isolate, host and environmental conditions.
  • Analysis of subviral RNA molecule (dRNA and satRNA) sequences and their evolution and analysis of structures/regions in genomes of auxiliary viruses that may affect their formation (analysis of recombination and secondary RNA structures).
  • Studying the effects of subviral RNA molecules on virus replication, disease symptoms and virus localisation in plant cells under study.


  • Identification and biochemical and molecular characterisation of new bacterial pathogens and phytoplasmas infesting crops and vegetables.
  • Development of methods for detection of plant bacteria and phytoplasmas (including real-time PCR, LAMP, HRM, Gen III Biologist System).
  • Studying sensitivity of bacteria to natural and artificial disinfectants.
  • Studying the pathogen-host-vector interactions (bacterium-plant-insect).
  • Identification of the role of common field weeds as a potential reservoir of bacteria and phytoplasmas pathogenic to crops.
  • Analysis of the occurrence and transmission of bacterial diseases and phytoplasmas.
  • Monitoring of winter rape crops for phytoplasma occurrence.
  • Detection of phytoplasmas in tissues using fluorescence microscopy.
  • Identification of phytoplasmic virulence factors.
  • Studying the composition of bacterial flora (bacteria and endosymbionts) of insects and plant pests.
  • Research on plant growth promoting bacteria (e.g. of the genus Serratia) and their application in plant breeding; Identification of molecular markers of genetic traits beneficial to plants.
  • Characterisation of antagonistic bacteria for popular plant pathogens.
  • Development of the composition of bacterial consortia (e.g. accelerating tomato growth, preventing the occurrence of storage diseases of crop plants, making it easier for plants to obtain phosphates, having antifungal properties).
