    Endocytic trafficking underlies processes essential for plant growth and development, including the perception of and response to abiotic and extracellular stimuli, post‐Golgi and exocytic trafficking, and cytokinesis. Protein adaptors and regulatory factors of clathrin‐mediated endocytosis that contribute to the formation of endocytic clathrin‐coated vesicles are evolutionarily conserved. Yet, work of the last ten years has identified differences between the endocytic mechanisms of plants and Opisthokonts involving the endocytic adaptor TPLATE complex, the requirement of actin during CME, and the function of clathrin‐independent endocytosis in the uptake of plant‐specific plasma membrane proteins. Here, we review clathrin‐mediated and ‐independent pathways in plants and describe recent advances enabled by new proteomic and imaging methods, and conditional perturbation of endocytosis. In addition, we summarize the formation and trafficking of clathrin‐coated vesicles based on temporal and structural data garnered from high‐resolution quantitative imaging studies. Finally, new information about the cross‐talk between endocytosis and other endomembrane trafficking pathways and organelles will also be discussed. Endocytic trafficking underlies processes essential for plant growth and development. This review (a) provides an overview of plant clathrin‐mediated and ‐independent endocytosis based on recent advances enabled by cutting‐edge proteomic and imaging methods and conditional perturbation of endocytosis, yielding high‐resolution structural and temporal details, and (b) discusses the cross‐talk between endocytosis and other endomembrane trafficking pathways and organelles.
