The endoplasmic reticulum (ER) carries out essential cellular functions ranging from protein trafficking to metabolite signaling. ER function is maintained in part by quality control pathways including ER degradation by selective autophagy (reticulophagy) during conditions of cellular stress. Reticulophagy is known to be important for cellular responses to starvation and protein folding stress, but no natural role during development had been identified. While investigating ER remodeling during the conserved cell differentiation process of meiosis in budding yeast, we unexpectedly observed developmentally regulated reticulophagy that was driven by expression of the autophagy receptor Atg40. This reticulophagy was coordinated with massive morphological rearrangement of the ER, including movement of most cortical ER away from the cell periphery. As meiotic reticulophagy prevents specific ER subpopulations from being inherited by gametes, we propose that it serves a quality control role, preventing deleterious material from being passed on to subsequent generations.
