text: Autophagosomes are double-membraned vesicles that traffic harmful or unwanted
cellular macromolecules to the vacuole for recycling. Although autophagosome biogenesis
has been extensively studied, autophagosome maturation, i.e., delivery and fusion
with the vacuole, remains largely unknown in plants. Here, we have identified
an autophagy adaptor, CFS1, that directly interacts with the autophagosome marker
ATG8 and localizes on both membranes of the autophagosome. Autophagosomes form
normally in Arabidopsis thaliana cfs1 mutants, but their delivery to the vacuole
is disrupted. CFS1’s function is evolutionarily conserved in plants, as it also
localizes to the autophagosomes and plays a role in autophagic flux in the liverwort
Marchantia polymorpha. CFS1 regulates autophagic flux by bridging autophagosomes
with the multivesicular body-localized ESCRT-I component VPS23A, leading to the
formation of amphisomes. Similar to CFS1-ATG8 interaction, disrupting the CFS1-VPS23A
interaction blocks autophagic flux and renders plants sensitive to nitrogen starvation.
Altogether, our results reveal a conserved vacuolar sorting hub that regulates
autophagic flux in plants.
