This work was led by PhD candidate Monique van Schie and proteomics wizard Mark Roosjen in our team.

We welcome any feedback to this work!

We hope that these maps will enable more protein-centred approaches in the plant sciences field, and many hypotheses to be generated. To enable this, we developed 5 Shiny apps (links in next post) to navigate the data.

We next compared spatial proteomes in the gnom mutant (BFA target) and wild-type, and identify a small set of proteins that move both after BFA treatment and in the gnom mutant. These include several well-known targets.

This shows the power of global dynamic subcellular proteome mapping

Where the maps are truly insightful is in the dynamic comparisons of global protein localization between conditions. We did this for a brief BFA treatment, and identify >800 proteins that change location. Most of these were not previously connected to BFA or trafficking.

The maps are a reference on their own, and now offer expertimentally defined subcellular localizations for thousands of proteins where this was not known. They can also be integrated with other proteomics datasets, as we show for targets and interactors of the BIN2 protein kinase

Comparing maps and localizations between orthologs in Arabidopsis and Marchantia shows that subcellular protein localization is strongly conserved, but also identifies a few hundred proteins whose localization diverged. These are enriched in membrane trafficking pathways.

Using fluorescently tagged lines, we show that >80% of these patterns check out, which is probably an underestimation.
We generated reference maps in Arabidopsis roots, Arabidopsis seedlings and Marchantia thallus, the latter also valildated with fluorescent markers.

We are very excited to share a new resource from our team: spatial subcellular proteome maps in plants! We developed an MS-based method that registers localizations of about 8000 proteins in Arabidopsis roots in a single experiment.
