Journal ArticleDOI
FM-dyes as experimental probes for dissecting vesicle trafficking in living plant cells.
TL;DR: Background information on the important characteristics of the FM‐dyes, and of optimal dye concentrations, conditions of dye storage, and staining and imaging protocols, are provided and particular emphasis is placed on using the FM-dyes in double labelling experiments to identity specific organelles.
Journal ArticleDOI
Plant peptides govern terminal differentiation of bacteria in symbiosis.

TL;DR: It is demonstrated that nodule-specific cysteine-rich NCR peptides are targeted to the bacteria and enter the bacterial membrane and cytosol and reveal a previously unknown innovation of the host plant that adopts effectors of the innate immune system for symbiosis to manipulate the cell fate of endosymbiotic bacteria.
Journal ArticleDOI
Remorin, a Solanaceae Protein Resident in Membrane Rafts and Plasmodesmata, Impairs Potato virus X Movement
Sylvain Raffaele,Emmanuelle Bayer,David Lafarge,Stéphanie Cluzet,Sylvie German Retana,Tamy Boubekeur,Nathalie Leborgne-Castel,Jean-Pierre Carde,Jeannine Lherminier,Elodie Noirot,Béatrice Satiat-Jeunemaitre,Jeanny Laroche-Traineau,Patrick Moreau,Thomas Ott,Andrew J. Maule,Philippe Reymond,Françoise Simon-Plas,Edward E. Farmer,Jean-Jacques Bessoule,Sébastien Mongrand +19 more
TL;DR: It is shown that REM can interact physically with the movement protein TRIPLE GENE BLOCK PROTEIN1 from PVX and the potential for lipid rafts to act as functional components in plasmodesmata and the plasma membrane is discussed.
Journal ArticleDOI
The C‐terminal HDEL sequence is sufficient for retention of secretory proteins in the endoplasmic reticulum (ER) but promotes vacuolar targeting of proteins that escape the ER
Véronique Gomord,Lise-Anne Denmat,Anne-Catherine Fitchette-Lainé,Béatrice Satiat-Jeunemaitre,Chris Hawes,Loïc Faye +5 more
TL;DR: It is proposed that, in addition to its function as an ER retention signal, HDEL could also act in quality control by targeting chaperones or chaperone-bound proteins that escape the ER to the plant lysosomal compartment for degradation.
Journal ArticleDOI
Sphingolipids Containing Very-Long-Chain Fatty Acids Define a Secretory Pathway for Specific Polar Plasma Membrane Protein Targeting in Arabidopsis
Jonathan E. Markham,Diana Molino,Lionel Gissot,Yannick Bellec,Kian Hématy,Jessica Marion,Katia Belcram,Jean Christophe Palauqui,Béatrice Satiat-Jeunemaitre,Jean-Denis Faure +9 more
TL;DR: It is shown that Arabidopsis has two classes of ceramide synthases discriminating acyl chain length and also that very-long-acyl-chain sphingolipids are required for polar auxin transport in particular during lateral root emergence and a trafficking pathway with specific endomembrane compartments and polar auxIn transport protein cargoes is defined.
