The hidden potential of South American Cortinarii

点击翻译按钮获取中文摘要

The aim of the project is to sample and eventually newly describe South American dermocyboid C., to isolate, identify their pigments, and to test the latter for photo-activity. As a base of the project, the taxonomy of endemic dermocyboid Cortinarii is resolved with extensive fieldwork, molecular network analysis of metabolites, and multi-gene phylogeny. Molecular network analysis is used for the first time here as metabolomic-taxonomical tool. Pigment profiles will be created by coupling thin layer chromatography and mass spectrometry using desorption electrospray ionization. (New) pigments will be isolated and their structure elucidated and tested for their biological activity with a focus on targeted light activation.
