LSU — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0131350 (LSU, IDS3) on barley chromosome 2H encodes a prenyl diphosphate synthase with all-trans-nonaprenyl-diphosphate synthase, FGPP synthase, geranyltranstransferase, dimethylallyltransferase, and farnesyltranstransferase activities. The gene is associated with geranylgeranyl diphosphate, geranyl diphosphate, farnesyl diphosphate, isoprenoid, ubiquinone, terpenoid, carotenoid, plastoquinone, and starch anabolism, as well as response to herbivore, insect, jasmonic acid, and salicylate, NO storage, proteolysis, and homeostasis. It has been linked to seed iron concentration. The product localizes to the plastid, chloroplast thylakoid membrane, etioplast, endoplasmic reticulum, and mitochondria, and is part of a polyprenyl diphosphate synthase complex. Related genes in other species are linked to sesterterpene production and carotenoid biosynthesis.
