PDS — Glycine max

Summary

GmPDS (GLYMA_18G003900V4) encodes a phytoene desaturase, an enzyme with 9,9'-di-cis-zeta-carotene desaturase and phytoene dehydrogenase activities that binds FAD. The gene is associated with carotene, strigolactone, hormone and carotenoid anabolism, appressorium formation, homologous recombination, response to herbicide, virus-induced PTGS, regeneration and nodulation. It is linked to auxin content, leaf shape, root length, and phenotypes including phytoene desaturation, chlorophyll biosynthesis, albino phenotype, primary root growth and lateral root formation. The product localises to plastid membranes, chloroplast thylakoid and envelope, and cytosol. Studies of related genes in other species link the family to carotenoid content, photobleaching, drought tolerance, chlorophyll homeostasis, plant height, chloroplast biogenesis and insect resistance.
