Membrane proteins of the PIN-FORMED (PIN) family exhibit polar localization in plant cells and facilitate cellular efflux of the plant hormone auxin, thereby regulating multiple developmental processes [1, 2]. PIN proteins undergo constitutive endocytosis and GNOM ARF GEF-dependent recycling [3-5], and their localization is under extensive regulation by developmental and environmental cues [6-9]. We designed a fluorescence imaging-based screen to identify Arabidopsis thaliana mutants defective in internalization of proteins including PINs from the plasma membrane. We identified three mutant loci, BFA-visualized endocytic trafficking defective1 (ben1) through ben3 that do not efficiently accumulate PIN1-GFP in intracellular compartments after inhibition of recycling and secretion by fungal toxin brefeldin A (BFA). Fine mapping revealed that BEN1 encodes an ARF GEF vesicle trafficking regulator from the functionally uncharacterized BIG class. ben1 mutant has been previously implicated in pathogen response [10] and shows cell polarity, BFA sensitivity, and growth defects. BEN1 is involved in endocytosis of plasma membrane proteins and localizes to early endocytic compartments distinct from GNOM-positive endosomes. Our results identify BEN1 as the ARF GEF mediating early endosomal traffic."}],"quality_controlled":0,"publisher":"Cell Press","issue":"5","publist_id":"3653","intvolume":"        19","volume":19,"_id":"3048","doi":"10.1016/j.cub.2009.01.057","title":"Fluorescence imaging based screen identifies ARF GEF component of early endosomal trafficking","author":[{"first_name":"Hirokazu","last_name":"Tanaka","full_name":"Tanaka, Hirokazu"},{"full_name":"Kitakura, Saeko","last_name":"Kitakura","first_name":"Saeko"},{"first_name":"Riet","last_name":"De Rycke","full_name":"De Rycke, Riet M"},{"full_name":"De Groodt, Ruth","last_name":"De Groodt","first_name":"Ruth"},{"id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596","last_name":"Friml","full_name":"Jirí Friml","first_name":"Jirí"}],"month":"03","date_updated":"2021-01-12T07:40:41Z","type":"journal_article","citation":{"chicago":"Tanaka, Hirokazu, Saeko Kitakura, Riet De Rycke, Ruth De Groodt, and Jiří Friml. “Fluorescence Imaging Based Screen Identifies ARF GEF Component of Early Endosomal Trafficking.” <i>Current Biology</i>.
