SAR1 — Triticum turgidum subsp. durum

Summary

TRITD6BV1G048510 (symbol SAR1, also known as TtNUP160) on durum wheat chromosome 6B encodes a nuclear pore complex protein NUP160, containing NUP160 helical and TPR domains, and is annotated as a structural constituent of the nuclear pore with protein-binding activity. The gene is associated with poly(A)+ mRNA export from the nucleus, secretion, developmental processes, regulation of the vegetative-to-reproductive phase transition, detoxification, and responses to auxin and cold. It localises to the nuclear pore complex, nuclear membrane, nuclear envelope, and nucleus. Associations include ethylene sensitivity, inflorescence morphology, mRNA export, basal and disease resistance, auxin response, meiotic chromosome condensation, and early flowering with small plants and compromised defense. Related genes in other species link the family to abiotic stress response, seedling growth, flowering time, ethylene response, auxin signalling, and cold stress tolerance.
