Progress in realisation of Preludium 21 (2022/45/N/NZ9/01923) project led by Dr. Weronika Babińska-Wensierska.
We are pleased to inform about the progress in the implementation of the project funded by the National Science Centre, Preludium 21 (2022/45/N/NZ9/01923), led by Dr. Weronika Babińska-Wensierska.
The research conducted within the presented project involves a detailed analysis of the soil microbiome in cultivated land, focusing on its impact on the development of diseases such as black leg and soft rot, caused by pectinolytic bacteria from the Dickeya spp. and Pectobacterium spp.
Head of the Preludium 21 project Dr. Weronika Babińska-Wensierska
The research results collected during the first year of the project were presented in oral and poster presentations at national and international conferences:

Importantly, the results obtained within the Preludium 21 project were part of Dr. Weronika Babińska-Wensierska’s doctoral dissertation entitled ” Characterisation of the Pectobacterium aquaticum isolated from Polish water in addition to studying the selected virulence and environmental factors important for development of potato blackleg and soft rot diseases”, supervisor: Prof. Ewa Łojkowska, auxiliary supervisor: Dr. Agata Motyka-Pomagruk.
We will keep you updated on further progress in the implementation of the Preludium 21 project.
Realization of the NCN Preludium Bis-1 project under the supervision of Prof. Ewa Łojkowska
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
