Transcription factors (TFs) regulate gene expression by binding to specific sequences on DNA through their DNA-binding domain (DBD), a universal process. This update conveys information about the diverse roles of TFs, focusing NACs (NAM-ATAF-CUC), in regulating target-gene and influencing various aspects plant biology. NAC TFs appeared before emergence land plants. The family constitutes group plant-specific found mosses, conifers, monocots, eudicots. discusses evolutionary origins genes/proteins from green algae crucial development stress response across species. From mosses lycophytes angiosperms, number proteins increases significantly, suggesting gradual evolution basal streptophytic algae. play critical role enhancing abiotic tolerance, with function conserved angiosperms. Furthermore, modular organization NACs, dimeric function, localization within cellular compartments contribute functional versatility complexity. While most are nuclear-localized active, subset is other compartments, indicating inactive forms until cues trigger translocation nucleus. Additionally, it highlights involvement endoplasmic reticulum (ER) stress-induced programmed cell death (PCD) activating vacuolar processing enzyme (VPE) gene.

Globally, rice is being consumed as a main staple food and faces different kinds of biotic abiotic stresses such drought, salinity, pest attacks. Through the cytokinin signaling, Type-B authentic response regulators (ARR-Bs) respond positively towards environmental stimuli. ARR-Bs are involved in stress tolerance plant development but their molecular mechanisms fragrant still not fully explored.
