HYD1 — Triticum turgidum subsp. durum

Summary

TRITD5AV1G001860 (symbol HYD1, also known as MAD4) on durum wheat chromosome 5A encodes a protein with C-8 sterol isomerase activity, steroid D-isomerase activity, and cholestenol D-isomerase activity, belonging to the EBP/EXPERA protein family. The gene is associated with carotenoid metabolism and anabolism, sterol anabolism, photoprotection, and cold acclimation. Its product localises to the ER membrane, ER, membrane, and nucleus. HYD1 is associated with lutein, zeaxanthin, carotene, and chlorophyll content, as well as spike length and plant height. It is linked to embryonic cell patterning, vascular tissue development, root growth, stomatal development, cellulose biosynthesis, and cell wall integrity. Related genes in other species are linked to embryonic development and root patterning.
