This study uses MALDI-MSI to map the spatial distribution of Amaryllidaceae alkaloids in Hippeastrum papilio, revealing tissue-specific patterns and challenging existing hypotheses on biosynthesis.

The paper evaluates spatial metabolomics protocols and technologies, showing extensive metabolite coverage and comparable results across imaging MS methods.

An open-source cloud engine annotates imaging mass spectrometry data at controlled false discovery rate; publicly shared results reached over 3200 datasets and 6 million metabolite images by January 2019.
