ERD8 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0678460 (HvERD8) on barley chromosome 7H encodes a heat shock protein 90 family member with ATP-dependent protein folding chaperone activity, also annotated for transcription regulator activity, siRNA and miRNA binding, RNA endonuclease activity, cis-trans proline isomerase activity, blue light photoreceptor activity, and ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase activity. The gene is associated with diverse biological processes including cellular response to brassinosteroid stimulus, photoentrainment of the circadian clock, UV protection, auxin metabolism, and negative regulation of cellulose anabolism. It is linked to traits such as maturity time, photoperiod-sensitive flowering, drought sensitivity, stem rust response, aphid response, seed viability, starch grain synthesis, and herbicide sensitivity. Localisation evidence connects the product to the chloroplast outer membrane, ER lumen, proteasome, and secretory vesicles.
