In eukaryotic cells, autophagosomes are double-membrane vesicles that are highly mobile and traffic along cytoskeletal tracks. While core autophagy-related proteins (ATGs) and other regulators involved in autophagosome biogenesis in plants have been extensively studied, the specific components regulating plant autophagosome motility remain elusive. In this study, using TurboID-based proximity labeling, we identify the retromer subcomplex comprising sorting nexin 1 (SNX1), SNX2a, and SNX2b as interacting partners of ATG8.
