Endogenous antimicrobial compounds in Chinese cabbage (Brassica rapa L.) upon viral and bacterial infections
The functions of phenolic compounds in plant defense range from physical and chemical barriers against infection to molecules involved in local and systemic signaling for defense gene induction. It was hypothesized that the flavonoid kaempferol could play an important role in signaling pathway in plant-pathogen interactions as well as that this process is conserved between plants. In this project we investigate the question whether these mechanisms are conserved between plants and whether different plant diseases can be controlled. To this end Brassica rapa L. infected with the cucumber mosaic virus (CMV) as well as with bacteria Pseudomonas will be used as a model plant. Quantitative assays, using Folin-Ciocalteu reagent, and qualitative analysis of phenolics, including flavonoids, using high performance liquid chromatography (HPLC) are carried out and the obtained results compared to Arabidopsis thaliana plants infected with CMV.
