Journal ArticleDOI
Regulation of selective autophagy: the p62/SQSTM1 paradigm
TL;DR: Autophagy receptors can induce local recruitment and activation of ULK1/2 and PI3KC3 complexes at the site of cargo sequestration, and Regulation of the capacity of the core autophagy machinery also affects selective autophagic.
Journal ArticleDOI
Plant NBR1 is a selective autophagy substrate and a functional hybrid of the mammalian autophagic adapters NBR1 and p62/SQSTM1
TL;DR: It is shown that AtNBR1 is an autophagy substrate degraded in the vacuole dependent on the polymerization property of the PB1 domain and of expression of AtATG7, which is similar to mammalian NBR1 and p62.
Journal ArticleDOI
Starvation induces rapid degradation of selective autophagy receptors by endosomal microautophagy.

TL;DR: Qualitative proteomics data support a model in which amino acid deprivation elicits endocytosis of specific membrane receptors, induction of macroautophagy, and rapid degradation of autophagy receptors by endosomal microautophagic.
Journal ArticleDOI
Turnip Mosaic Virus Counteracts Selective Autophagy of the Viral Silencing Suppressor HCpro
TL;DR: This study identified selective autophagy as antiviral pathway during plant infection with turnip mosaic virus (TuMV), a positive-stranded RNA potyvirus and found that NBR1-independent bulk Autophagy prevents premature plant death, thus extending the lifespan of virus reservoirs and particle production.
Journal ArticleDOI
Autophagy mediates temporary reprogramming and dedifferentiation in plant somatic cells

TL;DR: Observations indicate that autophagy mediates cell‐state switches that underlie somatic cell reprogramming in plants and possibly other organisms, and thereby promotes phenotypic plasticity.
