PER1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0120840 (symbol PER1) on barley chromosome 2H encodes a 1-Cys peroxiredoxin (EC 1.11.1.24) with thioredoxin-dependent peroxidase activity. The gene is associated with maintenance of seed dormancy, seed development, somatic embryogenesis, cellular oxidant detoxification, cell redox homeostasis, response to desiccation, nitric oxide storage, and defence response to fungi. Its product localises to the mitochondria, cytosol, cytoplasm, and nucleus. PER1 is linked to grain filling period, thermotolerance, seed dormancy, stress tolerance, and seed germination under stress. Related genes in other species are linked to seed germination, primary seed dormancy, oxidative stress tolerance, abiotic stress tolerance, and endosperm and root development.
