GLDH — Triticum aestivum

Summary

TRAESCS5B02G132600 (symbol TaGLDH) on bread wheat chromosome 5B encodes a protein with L-gulono-1,4-lactone dehydrogenase, galactonolactone dehydrogenase and D-arabinono-1,4-lactone oxidase activities, and binds FAD. This product belongs to the GL_DH and FAD_lactone_oxidase domain families and is localised to the mitochondrial membrane. The gene is associated with the formation of ascorbate from L-galactono-1,4-lactone, cofactor biosyntheses, and general metabolism and regulation. It has been linked to stomatal opening and aperture, and to drought tolerance. Related genes in other species have been linked to ascorbate and vitamin C biosynthesis, mitochondrial complex I assembly and accumulation, and plant viability, as well as to tiller number, plant height, panicle number, root length, seed viability, carotenoid content, and arsenic concentration.
