NAC transcription factors are considered as main family of transcriptional regulators in plants. NAC gene family members play significant contribution in regulating transcriptional reprogramming in plants related to plant stress response. These proteins possess highly conserved DNA binding domains and play a diverse functions in several plants. NAC gene is related to several stress factors including biotic and abiotic factors. NAC transcription factors controls several interrelated processes and their protein products can function as negative or positive regulators in many cellular processes. These regulatory functions are also controlled by NAC proteins such as auto and cross regulation. These regulatory proteins are regarded as a central regulator for the interaction of phyto hormones in various stress signaling pathways. This review highlights the role of NAC transcription factors in modulating gene expression and their role in various biotic and abiotic stress tolerance in plants.
