Editorial: Understanding the key border: Structure, function, and dynamics of the plant nuclear envelope

The Nuclear Envelope is a hallmark of eukaryotic cells. Despite its emerging role as a key structural and signaling platform, the plant NE remains one of the least understood membrane systems. This Frontiers Research Topic aims to highlight recent advances made to examine the role of the nuclear envelope (NE) as the “key border” in plants. Exploring this border is now proving hugely rewarding, with implications for many aspects of cell function and plant responses to the environment. Better understanding of this membrane system involves understanding its physical connections and its signaling and transport functions. Together they underpin its many functions- as an anchor and shaper; as a transport hub; and as a signaling center. The papers in this Topic provide current knowledge on all these aspects and a valuable basis for further advances
