Proposed model of CaSun1-CaAtg8 function in nitrogen starvation-induced mitophagy.

Caption

Proposed model of CaSun1-CaAtg8 function in nitrogen starvation-induced mitophagy. (A) Nitrogen starvation induces mitochondrial rupture and dysfunctional mitochondria, urging that CaSun1 recruits CaAtg8 to initiate the process of mitophagy. The autophagosomes encapsulating the mitochondria then fuse with vacuoles before degradation. (B) The ΔCasun1 mutant cannot efficiently remove dysfunctional mitochondrial by mitophagy in time, leading to damaged mitochondrial accumulation and abnormal mycelial physiology.
