NAC54 — Triticum aestivum

Summary

TRAESCS6D02G390200, also known as TaNAC2 or NAC54, encodes a NAC domain-containing protein on bread wheat chromosome 6D. The product is a sequence-specific DNA-binding transcription factor with protein homodimerization activity. This gene is associated with the regulation of endosperm development, secondary cell wall biogenesis, root cap development, and ribosome biogenesis. It is linked to ethylene, gibberellic acid, auxin, and abscisic acid signaling pathways, as well as responses to salinity and thirst. Associations with agronomic traits include grain weight per spike, grain yield, grain length, grain protein content, grains per spike, ear number, flag leaf senescence, stem rust and stripe rust disease responses, anther extrusion, and root branching. Studies of related genes in other species link the family to drought tolerance, leaf senescence, and seed germination.
