NAC26 — triticum aestivum

Summary

TRAESCS7A02G194700, designated NAC26 on wheat chromosome 7A, encodes a protein with a NAC domain and sequence-specific DNA-binding and protein homodimerization activity. The gene is associated with regulation of endosperm development, leaf senescence, lateral root development, embryogenesis, and ethene-mediated signalling. It is linked to lignin, starch, flavonoid and fatty acid metabolism, as well as activation of salinity response and GA-signalling. The encoded protein localises to both the nucleus and endoplasmic reticulum. NAC26 is associated with numerous grain quality and yield traits, including flour yield, starch yield, grain protein content, thousand kernel weight, seed dormancy, pre-harvest sprouting tolerance, grain iron and zinc content, amylose content, test weight, and seed hardness. It is also associated with diastatic power, flag leaf senescence, awn length, and responses to stem rust and stripe rust.
