We are pleased to announce a progress in the realisation of the NCN Preludium Bis-1 project (2019/35/O/NZ1/02751) granted to Prof. Ewa Łojkowska. A PhD student, Izabela Perkowska, who won the competition for the scholarship planned as a part of the project, is also involved in realisation of the research tasks besides her accessory supervisor Dr Anna Ihnatowicz. The project concerns the understanding of the role and mechanism of regulation of the expression of genes encoding dioxygenases in the process of plant adaptation to grow and develop on land. It is worth emphasizing that dioxygenases are the main group of enzymes involved in degradation of aromatic compounds.
During the course of the project, the research team has already collected very interesting data on the relationship between the accumulation of coumarins, iron deficiency and the susceptibility of the model plant Arabidopsis thaliana to Dickeya infection.
The following outcomes deserve special attention:
→ optimizing the growth of Arabidopsis thaliana in hydroponic cultures under conditions of abiotic stress (different levels of iron ions) and biotic stress (after inoculation of plants with a suspension of Dickeya sp.).
→ development of the 6-point disease severity scale (DSS)
→ optimization of the method for testing of the expression level of the genes coding dioxygenases in plants inoculated with Dickeya strains
Furthermore MSc Izabela Perkowska performed two interships:
- 09.2023 – 11.2023 (3 months) Laboratoire Agronomie et Environnement, Université de Lorraine INRA – UMT1121, Vandœuvre-lès-Nancy, France.
- 11.2021 (1 month) Laboratoire Agronomie et Environnement, Université de Lorraine INRA – UMT1121, Vandœuvre-lès-Nancy, France
