A clustered mitochondria family protein mediates the plant mitophagy (Curr. Biol.)
Plant Science Research WeeklyMitochondria function as cellular powerhouses to generate energy via oxidative phosphorylation and facilitate the synthesis of essential macromolecules. To protect against proteotoxic stress, damaged mitochondria are selectively removed by autophagy via a process known as mitophagy. In mammalian cells,…
Exo70B2 functions as a exocyst subunit in secretion linked to immunity and autophagy (Plant Cell)
Plant Science Research WeeklyThe exocyst is a conserved protein complex that mediates tethering of secretory vesicle to the plasma membrane prior to SNARE-mediated membrane fusion. Exo70 is one of eight subunits and has expanded into 23 homologs in Arabidopsis. Brillada and Teh et al. identified Exo70B2 as a bona fide exocyst subunit…

How to Eat One’s Feelings: Autophagy and Phosphatidylinositol 3-Phosphate
Blog, Research, The Plant Cell, The Plant Cell: In BriefMoving around taught me two essential skills, only one being relevant here: how to put up wallpaper, and how critical it is to label boxes to help the moving company drop them at their intended location. Now think of a cell: the boxes are vesicles, their contents are proteins and metabolites, and the…

A cross-kingdom conserved ER-phagy receptor maintains ER homeostasis during stress (eLIFE)
Plant Science Research WeeklyQuality control of the protein folding mechanism in the endoplasmic reticulum (ER), which selectively eliminates or recycles unwanted cytoplasmic components, is recognized by specific autophagy receptors. Selective removal of certain ER domains by the autophagy pathway (termed as ER-phagy) is controlled…
An interactome of plant autophagy proteins and pathogen effectors (Cell Host Microbe) ($)
Plant Science Research WeeklyAutophagy is a regulated process whereby select cytoplasmic components are degraded. It is involved in a variety of biological processes, including defense against pathogens. As such, plant pathogens have evolved mechanisms to target host autophagy machinery to gain virulence. However, we still lack…
Feasting While Fasting: How Autophagy Helps Maize Survive Carbon Starvation
Blog, Research, The Plant Cell, The Plant Cell: In BriefMost macro-molecular components of plant cells (e.g., proteins, lipids, and even entire organelles) are subject to an ongoing process of recycling to both rejuvenate aging structures and optimize the allocation of cellular nutrients. A major recycling route is autophagy, which occurs under normal conditions…
