The 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…

Moving 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…

Plantae Presents - Evo-devo. What can we learn from comparative studies? Recorded Wednesday, October 28 - 10 am EDT We're pleased to announce the second in our series of webinars that are drawn from contributed short videos, followed by a panel discussion. This week we'll look at the topic of…

Quality 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…

Autophagy 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…

Most 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…
