EDM1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0273490 (HvEDM1) on barley chromosome 3H encodes an Sgt1-like protein with domains including TPR repeats, a CS domain, and an HSP20-like chaperone domain, and exhibits molecular functions such as Hsp90 binding, ubiquitin ligase binding, SUMO transferase activity, and protein serine/threonine phosphatase activity. The gene is associated with upregulation of cellular defense response, respiratory burst involved in defense, response to humidity, heat, cold, and auxin stimulus, as well as RNA breakdown, chaperone-mediated protein complex assembly, and chloroplast stroma protein import. It localizes to the nuclear matrix, perinuclear region, SCF complex, stress granules, and chloroplast envelope. HvEDM1 is linked to traits including stem rust response, drought tolerance, flowering time, stomatal opening and closure, variegated leaf, cadmium concentration, and brassinosteroid sensitivity, along with phenotypes such as plant immunity, temperature-dependent seedling lethality, and effector-triggered immunity.
