Autophagy promotes programmed cell death and corpse clearance in specific cell types of the Arabidopsis root cap.

ABSTRACT: Autophagy is a conserved quality control pathway that mediates the degradation of cellular components by targeting them to the lysosomes or vacuoles.¹ Autophagy has been implicated in the regulation of some regulated cell death processes in animal systems.² However, its function in developmentally controlled programmed cell death (dPCD) in plants remains little studied and controversial.³ Some studies have reported autophagy pro-survival roles,^4,5 while others have suggested pro-death functions for autophagy,^6,7 calling for further detailed investigations. Here, we investigated the role of autophagy in dPCD using the Arabidopsis root cap as an accessible and genetically tractable model system
