Here, we identified and characterized the HYPERSENSITIVE TO LATRUNCULIN B1 (HLB1) protein isolated through a forward-genetic screen in <italic>Arabidopsis thaliana</italic> for mutants with heightened sensitivity to actin-disrupting drugs. HLB1 is a plant-specific tetratricopeptide repeat domain-containing protein of unknown function encoded by a single Arabidopsis gene. HLB1 associated with the <italic>trans</italic>-Golgi network (<xref ref-type="def" rid="def3">TGN</xref>)/early endosome (<xref ref-type="def" rid="def4">EE</xref>) and tracked along filamentous actin, indicating that it could link post-Golgi traffic with the actin cytoskeleton in plants. HLB1 was found to interact with the ADP-ribosylation-factor guanine nucleotide exchange factor, MIN7/BEN1 (HOPM INTERACTOR7/BREFELDIN A-VISUALIZED ENDOCYTIC TRAFFICKING DEFECTIVE1) by coimmunoprecipitation. The <italic>min7/ben1</italic> mutant phenocopied the mild root developmental defects and latrunculin B hypersensitivity of <italic>hlb1</italic>, and analyses of a <italic>hlb1/ min7/ben1</italic> double mutant showed that <italic>hlb1</italic> and <italic>min7/ben1</italic> operate in common genetic pathways. Based on these data, we propose that HLB1 together with MIN7/BEN1 form a complex with actin to modulate the function of the <xref ref-type="def" rid="def3">TGN</xref>/<xref ref-type="def" rid="def4">EE</xref> at the intersection of the exocytic and endocytic pathways in plants.</p></abstract><counts><page-count count="24"></page-count></counts><custom-meta-group><custom-meta><meta-name> DJS Export </meta-name><meta-value>v1</meta-value></custom-meta></custom-meta-group></article-meta><notes><glossary><title>Glossary</title><def-list><def-item><term id="term1">ER</term><def id="def1"><p>endoplasmic reticulum</p></def></def-item><def-item><term id="term2">PM</term><def id="def2"><p>plasma membrane</p></def></def-item><def-item><term id="term3">TGN</term><def id="def3"><p><italic>trans</italic>-Golgi network</p></def></def-item><def-item><term id="term4">EE</term><def id="def4"><p>early endosome</p></def></def-item><def-item><term id="term5">LatB</term><def id="def5"><p>latrunculin B</p></def></def-item><def-item><term id="term6">DIC</term><def id="def6"><p>differential interference contrast</p></def></def-item><def-item><term id="term7">TPR</term><def id="def7"><p>tetratricopeptide repeat</p></def></def-item><def-item><term id="term8">BFA</term><def id="def8"><p>Brefeldin A</p></def></def-item><def-item><term id="term9">PVC</term><def id="def9"><p>prevacuolar compartment</p></def></def-item><def-item><term id="term10">co-IP</term><def id="def10"><p>coimmunoprecipitation</p></def></def-item><def-item><term id="term11">MS</term><def id="def11"><p>Murashige and Skoog</p></def></def-item></def-list></glossary></notes></front></pmc><affiliations><list><country><li>États-Unis</li></country><region><li>Michigan</li><li>Oklahoma</li></region></list><tree><country name="États-Unis"><region name="Oklahoma"><name sortKey="Sparks, J Alan" sort="Sparks, J Alan" uniqKey="Sparks J" first="J.
