ERF3 — Triticum aestivum

Summary

TRAESCS6B02G210300, designated TaERF3 (also known as TaWIN1-6B, TaSHN1, TaSHN2, TaSHN3), encodes an AP2/ERF domain-containing transcription factor on wheat chromosome 6B. The protein possesses sequence-specific DNA binding and transcription factor activity, and is associated with wax, cuticle, and cutin metabolism, aldehyde anabolism, and ethylene-mediated signaling. TaERF3 is associated with heat tolerance, osmotic and stress responses, detoxification, and growth. It is also associated with grain weight, grain width, grain yield, stripe rust resistance, plant height, anthesis time, seed germination, chlorophyll content, anthocyanin content, and stomatal resistance. The gene product localizes to the nucleus and protoplasm. Studies of related genes in other species link the family to leaf surface wax content, cutin biosynthesis, defense responses, drought, salt, and osmotic stress tolerance.
