RT   "A NAC Gene regulating senescence improves grain protein, zinc, and iron
RT   content in wheat.";
RL   Science 314:1298-1301(2006).
CC   -!- FUNCTION: Transcription factor of the NAC family associated with the
CC       grain protein content (GPC). Accelerates senescence and increases
CC       nutrient remobilization from leaves to developing grains. The
CC       tetraploid cultivated wheat (T.durum) and the hexaploid wheat
CC       (T.aestivum) carry a one bp insertion generating a non-functional
CC       allele of this gene. They have a delayed senescence and a lower grain
CC       protein, zinc and iron content (PubMed:17124321).
CC       {ECO:0000269|PubMed:17124321}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC   -!- DOMAIN: The NAC domain includes a DNA-binding domain and a dimerization
CC       domain.
CC   -!- MISCELLANEOUS: High grain protein content (GPC) is a desirable trait in
CC       breadmaking and pasta wheat varieties because of its positive effects
CC       on quality and nutritional value while Low GPC is a desirable trait for
CC       barley malt and beer production.
