Matrix assisted laser desorption/ionization-mass spectrometry imaging (MALDI-MSI) for direct visualization of plant metabolites in situ

- Plant chemical organization is visualized directly using MALDI-MSI.
- MALDI-MS imaging of plant tissues reveals unforeseen analyte compartmentalization.
- Analyte heterogeneity has been validated by other MS and biochemical analyses.
- Novel instrument modifications have driven spatial and chemical resolution to unprecedented levels.
