Rubisco is degraded during leaf senescence, and its components are recycled within the plant. Although Rubisco can be mobilized to the vacuole by autophagy via specific autophagic bodies, the importance of this process in Rubisco degradation has not been shown directly. Using an assay based on the processing of fluorescent protein‐tagged Rubisco, here, we provide further evidence for the contribution of autophagy to Rubisco degradation during both natural and promoted leaf senescence in Arabidopsis.
