NBR1-mediated selective autophagy in plant stress responses. The cargo proteins and biological roles of NBR1 in aggrephagy, heat stress memory, antiviral defense and Exo70E2 are well supported by biochemical, molecular and genetic evidence. Studies through analysis of protein localization, gene expression, protein-protein interactions and transgenic overexpression have also suggested possible roles of NBR1 in stress-induced pexophagy, S nutrient response and ABA signaling.
