Plasmodesmata, a Maze of Questions

This book bears witness to quantum leaps in the knowledge of plasmodesmal structure, functioning and function. At the same time, much is still obscure. Any overview of the literature on plasmodesmata reveals a multitude of untouched areas, uncertainties, uncertified assumptions and controversies. The number of those pertaining to basic issues is striking. One is tempted to believe, therefore, that we are only beginning to explore the amazing properties of plasmodesmata. In this chapter, an attempt is made to list some of the unresolved questions. Several of them are discussed more extensively in the following chapters, while others are only touched upon or hardly taken into consideration. Our goal here is to identify a few challenging areas and sketch some prospects on future plasmodesmal research.
