cropPAL2020 provides a powerful tool to investigate subcellular localisation in a growing number of crop species through the unification of disparate datasets and by the provision of web services through our accessible interface. Users can construct powerful queries or interrogate their protein sets resulting in a one-stop-shop for protein localisation and protein location relationships. The compendium of cropPAL2020 houses large scale proteomic (MS/MS), fluorescence protein (FP) localisation as well as Protein-Protein Interaction (PPI) inferred from Arabidopsis PPI experimentation.
