Endocytosis is a fundamental biological process, which is conserved among all eukaryotes. It is essential not only for many physiological and signalling processes but also for interactions between eukaryotic cells and pathogens or symbionts. This book covers all aspects of endocytosis in both lower and higher plants, including basic types of endocytosis, endocytic compartments, and molecules involved in endocytic internalization and recycling in diverse plant cell types. It provides a comparison with endocytosis in animals and yeast and discusses future prospects in this new and rapidly evolving plant research field. Readers will find an overview of the state-of-the-art methods and techniques applied in plant endocytosis research.
