Abstract

AbstractThe proteins of the nuclear envelope have been characteriszd in detail in non‐plant systems, revealing a complex series of interactions between the inner and outer nuclear envelope, with the proteins of the nuclear pore complex and connecting to the nucleoskeleton and cytoskeleton. Many of the proteins described in animal and fungal systems have not been identified in plants; however, recent advances have resulted in the description of several key plant nuclear envelope proteins including members of the Sad1/UNC84 (SUN) domain family and recently the first Klarsicht/Anc‐1/Syne‐1 Homology (KASH)‐domain protein. This chapter describes the emerging networks of protein interactions at the plant nuclear envelope, together with discussion of their likely functions. In particular, the important role of plant SUN domain proteins as a key component of a linker of nucleoskeleton and cytoskeleton complex is described together with prospects for future study of plant nuclear envelope interaction networks.
