Abstract

The nuclear pores form the gateways connecting the nucleoplasm of eukaryotic cells with the cytoplasm. They are essentially fusions of the inner and outer nuclear membranes forming a connecting pore membrane and a “hole” in the nuclear envelope. They are organized and anchored by a multi-protein complex termed the nuclear pore complex (NPC), which facilitates and regulates the transport of molecules across the barrier provided by the nuclear envelope. While proteomics analysis has unraveled the molecular composition of the vertebrate and yeast NPC, our knowledge of the plant nuclear pore is still far from comprehensive. However, several components of the plant NPC and nucleocytoplasmic transport machinery have emerged in recent mutant screens and were found to affect diverse processes ranging from plant—microbe interactions and hormone and stress responses to development and the regulation of flowering time. Taken together, these studies illustrate the importance of the NPC and nucleocytoplasmic transport in the regulation of plant growth and responses to the environment.
