The process in which cells degrade mitochondria by inducing a vacuole-like structure which directly engulfs and degrades the unhealthy mitochondria by accumulating lysosomes.
Comment:
In this mechanism of mitochondrion degradation, the mitochondrion is directly engulfed by a lysosome-like vacuole. It is therefore distinct from canonical autophagy, which is mediated by a double-membrane autophagosome.
