AKR — Medicago truncatula

Summary

MTR_5G097940 (symbol AKR) on barrel medic chromosome 5 encodes a member of the AKR4A/B subfamily of aldo-keto reductases, with annotated D-galacturonate reductase, 6'-deoxychalcone synthase, codeinone reductase (NADPH), 3''-deamino-3''-oxonicotianamine reductase, and aldose reductase (NADPH) activities. The gene is associated with secondary metabolite biosynthesis, including flavonoid and alkaloid anabolism and metabolism, as well as ascorbate biosynthesis and siderophore anabolism. It is associated with responses to salt, iron ion starvation, and zinc starvation, and with leaf senescence and hypersensitivity. The encoded protein localises to the cytosol. Studies of related genes in other species link the family to seed protein content, sulfur content, linoleic acid content, seed maturation, stomatal opening, and photochemical quenching.
