ERD8 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G089150 (ERD8) on durum wheat chromosome 7A encodes a heat shock protein 90 (Hsp90) family member with ATP-dependent protein folding chaperone activity, along with annotated functions including transcription regulator activity, RNA endonuclease activity, and blue light photoreceptor activity. The gene is associated with powdery mildew resistance in durum wheat and has been linked to numerous processes including cellular response to brassinosteroid stimulus, auxin metabolism, UV protection, gene silencing by miRNA, chloroplast localization, and cytosol-to-ER transport. Associations extend to traits such as maturity time, photoperiod-sensitive flowering, seed viability, and responses to various pathogens including downy mildew. The protein localizes to the ER lumen, chloroplast outer membrane, and proteasome.
