HY5 Positively Regulates Autophagy to Mediate Red Light‐Induced Tomato Fruit Ripening
Plant Biotechnology Journal, EarlyView.ABSTRACT Red light accelerates tomato fruit ripening, but the molecular link between light signalling and autophagy remains unclear. Here, we show that red light promotes fruit coloration by activating autophagy in tomato pericarp. This response largely depends on the transcription factor HY5, which positively regulates this process by directly ...

Plant, Cell &Environment, EarlyView.ABSTRACT The anaphase‐promoting complex/cyclosome (APC/C) is a multi‐subunit E3 ubiquitin ligase that regulates cell cycle progression, but its role in plant‐pathogen interactions is poorly understood. Here, we demonstrate that regulation of the ubiquitin–proteasome system, involving APC/C‐associated components, is critical for coordinating host cell ...

Molecular insights and translational opportunities to enhance heat tolerance in rice
The Plant Genome, Volume 19, Issue 3, September 2026.Abstract Heat stress is an increasingly serious threat to rice (Oryza sativa L.) productivity, yet the genetic and regulatory architecture underlying thermotolerance remain poorly resolved and fragmented across studies. Earlier research focused on individual pathways or specific developmental stages; however, recent advances now support an integrated ...

Coordination of Autophagosome–Lysosome Fusion by Atg8 Family Members [PDF]
Current Biology, 2018 Macroautophagy is a conserved intracellular lysosomal degradative pathway, vital for the maintenance of cellular homeostasis. It is characterized by double-membrane vesicles called autophagosomes, which sequester the cytoplasmic material destined for lysosomal turnover. In a final step, autophagosomes fuse with lysosomes to release their cargo into the

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers
Chemistry – A European Journal, Volume 32, Issue 30, 13 August 2026.ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

MicroorganismsAutophagy is an essential eukaryotic catabolic process through which damaged or superfluous cellular components are degraded and recycled via the formation of double-membrane autophagosomes.

PLoS ONE, 2012 Autophagy is a membrane-mediated degradation process, which is governed by sequential functions of Atg proteins. Although Atg proteins are highly conserved in eukaryotes, protozoa possess only a partial set of Atg proteins.

Nature Communications, 2020 The ER is subject to autophagy (ER-phagy) for turnover, with Atg40 acting as a receptor to sequester ER with Atg8 in autophagosomes. Here, the authors show that Atg40 is clustered by interaction with Atg8 to generate local membrane curvature and promote ...

Advanced Science, Volume 13, Issue 48, 28 August 2026.Ubiquilin (UBQLN), like many other human proteins, contains both well‐folded and disordered regions. Here, we show that intramolecular interactions between disordered regions and folded domains modulate between open and closed topologies of UBQLN proteins, altering their structure and function.
