ZDS — Triticum turgidum subsp. durum

Summary

TRITD2BV1G099850 (ZDS, TtZDS) on durum wheat chromosome 2B encodes a zeta-carotene desaturase with 9,9'-di-cis-zeta-carotene desaturase and phytoene dehydrogenase activities, binding FAD and localizing to the chloroplast thylakoid and envelope. This gene is associated with carotenoid and zeaxanthin content, as well as lycopene, carotene, and carotenoid anabolism, and pigment breakdown. It is linked to chloroplast and leaf development, retrograde signalling, abscisic acid biosynthesis, photoprotection, plant growth, and response to herbicide. Related genes in other species are associated with grain yield, weight, size, texture, protein content, flour color, amylose and amylopectin content, anthesis time, plant height, leaf stomatal conductance, transpiration rate, chlorophyll content, and pre-harvest sprouting.
