Autophagy, which is believed to be an Atg7- and Atg3-dependent process, is known to be involved in animal development. Baehrecke and colleagues show that autophagy drives the controlled degradation of the developing Drosophila midgut. Interestingly, this process is Atg7- and Atg3-independent, and instead requires the E1-activating enzyme Uba1 for programmed reduction of cell size in the midgut.
