Plants have an additional organelle to animals (the chloroplast), which means that they have a greater repertoire of protein homeostasis (proteostasis) mechanisms. We find that chloroplast proteostasis components prevent aggregation of a pathogenic fragment of human huntingtin expressed in plants, which reveals a potential avenue for therapeutic intervention in human proteinopathies.
