Special Issue Information

Dear Colleagues,

Autophagy is a conserved catabolic program of degradation of cytoplasmic components in lytic acidic compartments, intrinsic to all eukaryotic cells. In plants, selective autophagy is an essential mechanism of quality control of organelles and elimination of dysfunctional cell constituents, thus maintaining cell homeostasis. Various abiotic stresses lead to a strong activation of autophagy, which, apart from clearance of damaged cell parts, enables bulk degradation of non-essential cell constituents providing energy and ‘building blocks’ for the maintenance of vital cell parts and functions. Autophagy involves a sophisticated cellular machinery, the core of which is formed by ATG proteins. Bulk autophagy results in large-scaled remodeling of cell structure and metabolism.

The pro-survival role of autophagy in plant cells during stress has been confirmed in many studies. Intriguingly, autophagy can be recruited to serve as a mechanism of programmed cell death (PCD) during development, and was suggested to play a similar role in some cases of stress-induced PCD. The fine-tuned interplay between autophagy and PCD during the plant immune response is critical for the resistance to diverse pathogens. This Special Issue invites research papers and reviews about the molecular and cellular mechanisms and regulators of autophagy, as well as the variety of roles autophagy plays in cells of plants and algae.

Title: ER-phagy and its role in ER homeostasis in plants
Authors: Yan Bao; Diane C. Bassham

Abstract: The endoplasmic reticulum (ER) is the largest continuous membrane-bound cellular organelle and plays a central role in the biosynthesis and distribution of lipids and proteins to other organelles. Autophagy is a conserved process that is required for recycling unwanted cellular components, and recent studies have implicated the ER as a membrane source for the formation of autophagosomes, vesicles that transport material to the vacuole during autophagy. Upon a condition known as ER stress, in which unfolded proteins accumulate in the ER and/or the ER lipid bilayer is disrupted, ER membranes can also be engulfed through autophagy, a process that is termed ER-phagy. An interplay between ER stress responses and autophagy thus maintains the functions of the ER to allow cellular survival. In this review, we discuss recent progress in understanding ER-phagy in plants, including identification of regulatory factors and selective autophagy receptors, and identify key unanswered questions in plant ER-phagy for future study.
