ERD8 — Triticum aestivum

Summary

TaERD8 (TRAESCS7B02G149200) on wheat chromosome 7B encodes an HSP90 family chaperone with ATP-dependent protein folding activity, annotated with functions including transcription regulator activity, siRNA and miRNA binding, RNA endonuclease activity, and blue light photoreceptor activity. In bread wheat, TaERD8 is associated with powdery mildew resistance and is linked to salicylic acid signaling, hormone signaling pathways, and HSF1 transcription. The gene has been associated with numerous traits including maturity time, reproductive growth, starch grain synthesis, stem rust and aphid response, photoperiod-sensitive flowering, seed viability, root hair length, and herbicide sensitivity. It is also associated with downy mildew resistance, plant immunity, heat stress response, and male sterility. Studies of related genes in other species link the family to embryo development, heat shock response, floral transition, photoperiodic flowering, drought memory, and pathogen resistance.
