🔎 SPECIAL ISSUE VIEWPOINT 🔎 A variety of motifs mediate protein localization at plasmodesmata. Should they be viewed as targeting or retention signals? Barr & Tilsner explore the motifs and mechanisms underlying plasmodesmal protein localization ⚙️ 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪
Fig. 1.Conceptual illustration of retention of plasmodesmata (PDs) components paired with plasma membrane (PM) and endoplasmic reticulum (ER) trafficking mechanisms. (A) PM-associated proteins traffic to the bulk PM via the Golgi body and secretory pathway. (B) Ribosomes associated with the rough ER traffic ER-associated proteins to the bulk ER. (C) The specialized composition at PDs indicated with labels and illustrated with colour gradients: the cortical ER (green) and PD–ER (navy blue), and the bulk (light blue) and specialized (purple) cell wall (CW). Magenta outlining conceptualizes the properties of PD-retained proteins clustered to the PD-specific membranes.

📢 New plant science textbook Staff and alumni from our institute and @thesainsburylab.bsky.social have recently published Essential Plant Biology, a new textbook presenting current and comprehensive knowledge of plant biology 🌱
Alison Smith, Author and Emeritus Fellow at the John Innes Centre said, “We were inspired to write this book by the stimulating, creative and supportive environment provided by our JIC and TSL colleagues. It is intended to provide a new generation of plant scientists with an appreciation of the wealth and breadth of radically new knowledge and technologies in plant science. The book also reveals some of the exciting opportunities for fundamental discovery and innovation in plant science to help tackle global challenges including sustainable food production, environmental pollution, climate change and biodiversity loss.”
