Should I stay or should I go? Traffic control for plant pattern recognition receptors

- PM-localised PRRs undergo constitutive recycling and ligand-induced endocytosis.
- Ligand-induced endocytosis is conserved between species and across PRR families.
- PRRs are sorted for distinct subcellular destinations in an activation-dependent manner.
- PRR trafficking is involved in regulation of receptor localisation and defence signalling.
