nud — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0719680, symbol nud, on barley chromosome 7H, encodes an AP2/ERF transcription factor (ERF subfamily) with sequence-specific DNA-binding activity, localised to the nucleus. The gene is associated with upregulation of wax anabolism and cuticle anabolism, as well as responses to ethylene, abscisic acid, drought, osmotic stress, and defence. It is linked to the naked caryopsis (nud) grain morphology trait. The gene has also been connected to nodulation and regulation of DNA-templated transcription. Studies of related genes in other species link the family to heat tolerance and salt tolerance, and to high temperature stress response and drought tolerance.
