MALDI-TOF/TOF tandem mass spectrometry imaging reveals non-uniform distribution of disaccharide isomers in plant tissues

[Display omitted] •A tandem mass spectrometry imaging method was developed to visualize disaccharide isomers in plant tissues.•Disaccharide isomers have different location in plant tissues.•New disaccharide isomers besides sucrose were found in onion bulbs. Mass spectrometry imaging (MSI) is a power...
