ERD8 — Brachypodium distachyon

Summary

BdERD8 (BRADI_3G39620V3) on chromosome 3 of Brachypodium distachyon encodes a heat shock protein 90 family member (Hsp90) with ATP-dependent protein folding chaperone activity, ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase activity, transcription regulator activity, siRNA and miRNA binding, RNA endonuclease activity, cis-trans proline isomerase activity, blue light photoreceptor activity, and LRR domain binding. It is associated with cellular responses to brassinosteroid stimulus and calcium ions, photoentrainment of the circadian clock, auxin metabolism, root hair cell differentiation, leaf pattern formation, quiescent center organization, and UV protection. The gene is linked to traits including maturity time, reproductive growth time, photoperiod-sensitive flowering, seed viability, starch grain synthesis, shoot meristem development, and responses to downy mildew, aphids, viral disease, and heat stress. Related genes in other species connect the family to embryo development, floral transition, and temperature compensation.
