Description of the project Introduction


In the past few years, the increased production and consumption of fresh vegetables, was accompanied by increased number of reports of food-borne diseases caused by HPMOs. The origin of HPMOs can be diverse: polluted soils enriched with organic fertilisers, crops irrigated with contaminated waters, or the faeces of free-living animals. It should be noted that many of the microorganisms that naturally accompany plants (endophytic or rhizosphere microorganisms) might be opportunistic human pathogens.


The main goal of the project is: (i) to determine the diversity and incidence of HPMOs in rhizosphere and tissues of crops communities, (ii) to determine HPMOs influence on plant as well as on microbiome diversity and the endophytes abundance in vitro and in pot experiment.


Expected results. Received results will: (i) extend the knowledge of plant–HPMO interactions with staple crops, (ii) reveal mechanisms limiting or preventing infection of plants by HPMOs.

In this proposal we investigate whether staple crops synthesizes specific compounds with anti-HPMO properties and whether its unique microbiome limits the colonization of tissues by HPMOs. Complexity of mechanisms determining interaction between plants and pathogens results in the lack of repeatability and predictability in terms of infection outcome and level. It will probably take many years of work to develop technologies for producing vegetables that are free of HPMOs or have increased susceptibility to infection by HPMOs. The production of safe food (i.e., HPMOs-free) is an extremely important issue, especially considering the increasing number of HPMOs present in plant production systems. The PhD project will be conducted under the framework of COST Action 16110 Control of Human Pathogenic Microorganisms in Plant Production Systems. Supervisor of this project prof. K. Hrynkiewicz is part of the Management Committee of this Action (|Name:management-committee).

The project is conducted in cooperation with: Dr. rer. Nat. habil. Silke Ruppel, Leibnitz-Institute of Vegetable and Ornamental Crops, Großbeeren, Germany, Department of Plant nutrition, Germany.

Principal supervisor: Prof. dr hab. Katarzyna Hrynkiewicz, Chair of Microbiology, Faculty of Biology and Environmental Protection, Nicolaus Copernicus University in Torun, Poland.


Subsidiary supervisor: will be assigned.
