Abstract: Transcription factors, the proteins with special structures, can bind to specific sites and regulate specific expression of target genes. NAC (NAM, ATAF1/2, CUC1/2) transcription factors, unique to plants, are composed of a conserved N-terminal domain and a highly variable C-terminal transcriptional activation domain. NAC transcription factors are involved in plant growth and development, responses to biotic and abiotic stresses and other processes, playing a regulatory role in flower development. In this paper, we reviewed the studies about NAC transcription factors in terms of discovery, structure, and regulatory roles in anther development, other floral organ development and flowering time. This review will provide a theoretical basis for deciphering the regulatory mechanism and improving the regulatory network of NAC transcription factors in flower development.
