PDS1 — Brachypodium distachyon

Summary

BRADI_1G72400V3 (BdPDS1) on chromosome 1 encodes a phytoene desaturase with 9,9'-di-cis-zeta-carotene desaturase and phytoene dehydrogenase activities, binding FAD. The gene is associated with carotene and chlorophyll anabolism, protein homotetramerization, response to herbicide, virus-induced PTGS, and DNA recombination. It localizes to the plastid membrane, chloroplast thylakoid and envelope, membrane, and cytosol. The gene is linked to phytoene desaturation, chlorophyll biosynthesis, albino phenotype, lateral root formation, and primary root growth. Studies of related genes in other species connect the family to carotenoid, lycopene, lutein, and zeaxanthin content, grain color and yield, plant height, seed germination and maturation, drought tolerance, stripe rust resistance, leaf stomatal conductance, transpiration, chloroplast development, photobleaching, and insect resistance.
