HPD — Glycine max

Summary

GmHPD (GLYMA_14G030400V4) on soybean chromosome 14 encodes a 4-hydroxyphenylpyruvate dioxygenase, an iron-binding enzyme with conserved dioxygenase domains. The gene is associated with plastoquinone and tocopherol biosynthesis, carotenoid anabolism, tyrosine and L-phenylalanine catabolism, and vitamin E metabolism. It has been connected to herbicide response, virus-induced PTGS, and shoot regeneration. Localization evidence links the product to the cytosol, mitochondria, and extracellular space. Related genes in other species are linked to tocopherol content, herbicide binding, and photosynthesis, as well as leaf necrosis, seed weight, seed size, chlorophyll content, and salt tolerance.
