HYD1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G001720 (HYD1, TtHYD1) on durum wheat chromosome 5B encodes a protein with C-8 sterol isomerase activity, steroid D-isomerase activity, and cholestenol D-isomerase activity, belonging to the EBP/EXPERA domain family. The gene is associated with carotenoid metabolism, sterol anabolism, photoprotection, and cold acclimation, and localises to the ER membrane, membrane, and nucleus. It is linked to lutein content, zeaxanthin content, carotene content, carotenoid content, chlorophyll content, spike length, and plant height. Associations also include embryonic cell patterning, embryonic development, vascular tissue development, seedling morphogenesis, root growth, cell expansion, stomatal development, root patterning, cellulose biosynthesis, cell wall integrity, and embryogenesis. Studies of related genes in other species connect the family to spikelet number and root thickness.
