The biotechnological importance of the plant-specific NAC transcription factor family in crop improvement

Abstract Climate change, malnutrition, and food insecurity are the inevitable challenges being faced by agriculture sector today. Plants susceptible to extreme temperatures during crucial phases of flowering seed development, elevated carbon levels also lead yield losses. Productivity is affected floods droughts. Therefore, increasing plant stress tolerance priorities be met through novel biotechnological interventions. The contributions NAC genes towards enhancing survivability under well known. Here we focus on potential in regulation abiotic tolerance, secondary cell wall synthesis, lateral root potential, size biomass, ROS signaling, leaf senescence, programmed death. Once naturally tolerant candidate have been identified, nature their association with growth fitness against multi-environmental stresses has determined, they can exploited for building inherent future crops via transgenic technologies. An update latest developments provided this review, which summarizes current understanding roles establishment various stress-adaptive mechanisms model crop plants.
