Abstract: Abstract: Membrane-bound NAC transcription factors are a group of NAC transcription factors with transmem-brane domain. They contain a highly conserved NAC domain in N-terminal ends and a membrane-bound motif in C-terminal ends. It was reported that membrane-bound NAC transcription factors play important roles in multiple biological functions such as development， growth， responses to stresses. This article reviewed characters of structure， biological function， mechanism of regulation of plant membrane-bound NAC transcription factors， as well as the recent research progress.
Key words: membrane-bound NAC transcription factors; structure; biological function; mechanism of regulation
