Spin-off project: Analysis of the biodiversity of glucosinolate compounds in cabbage vegetables

IGZ/V. Púčiková

317 cabbage varieties were cultivated on the IGZ trial field to analyze their biodiversity.

Together with the Leibniz Institute for Food Systems Biology at the Technical University of Munich (LSB), the IGZ has acquired funding for the computer-aided analysis of metabolite profiles in cabbage species. The project complements the work of the "SharpGreens" project, which is investigating how human health can be improved with the help of cabbage vegetables. Here, cabbage varieties with a high content of health-promoting plant constituents are identified in order to develop innovative foods from them.

Brassica vegetables are rich in various phytochemicals that support immune function and prevent chronic diseases in humans. A large proportion of these protective effects are attributed to certain degradation products of mustard oil glycosides, the glucosinolates. These secondary metabolites are modified by specific plant enzymes. In order to better understand their accumulation in cabbage vegetables and thus improve plant quality, the different hydrolysis patterns are to be investigated and the modifying proteins identified.

The aim of the project is therefore to use multi-variant data analysis methods to identify variety-specific patterns in the formation of secondary metabolites in cabbage vegetables (Brassica oleracea) with regard to their evolutionary relationships. In addition, they will serve as clues for the characterization of previously unknown modifying enzymes.

Metabolite profiles of 317 varieties of cabbage serve as the data basis: kohlrabi, white cabbage, red cabbage, savoy cabbage, cauliflower, Chinese broccoli and kale. The profiles originate from a field trial at the IGZ in summer 2023. The results will be made available as an interactive web application within the Food Systems Biology Database.

The project, which is funded by the Leibniz Association, lays the foundation for an in-depth joint collaboration between IGZ and LSB for the computer-aided analysis of multi-omics data sets and the application of the two institutes' complementary analytical platforms. The current project, headed by Dr. Katja Witzel, will start on 01.12.2024 and run for a period of twelve months. Dr. habil. Franziska Hanschen (IGZ), Vanda Púčiková (IGZ) and Dr. Andreas Dunkel (LSB) complete the research team. The Leibniz Research Network "Active Ingredients" supports collaborations between Leibniz institutes within the framework of "Seed Money" projects with up to €10,000.
