The energy sensor SnRK1 promotes starvation-induced autophagosome formation by modulating ATG13a phosphorylation in Arabidopsis.
In eukaryotes, autophagy is an evolutionarily conserved cellular degradation and recycling process that is tightly associated with cellular nutrient status. The energy sensor SNF1-RELATED KINASE 1 (SnRK1) is thought to sense nutrient starvation and induce autophagy, but how it regulates autophagosome formation in plant...
