The goal of the Plant Cell Atlas (PCA) is to bring together a community who will comprehensively describe plant cell types by integrating high-resolution subcellular and cellular location information of nucleic acids, proteins, and metabolites. In line with achieving this goal, metabolomics provides a functional readout of the cellular and molecular programs controlled through expression of genes and proteins, as metabolites are directly linked to cellular function, response to environmental stresses, and progression to disease.
 Significant advances in mass spectrometry imaging and spatially resolved mass spectrometry technologies now make high-spatial resolution metabolomics notably more accessible for plant science. Moreover, new multiomics methods, including spatially resolved approaches, enable the ability to directly connect transcriptional and proteomic signatures with metabolic activity. This second PCA workshop on spatial metabolomics aims to bring together world leaders in spatial and mass spectrometry imaging-based metabolomics from plant sciences and beyond to help realize the development of a comprehensive PCA metabolome.
