HPD — Glycine max

Summary

GmHPD (GLYMA_02G284600V4) encodes a 4-hydroxyphenylpyruvate dioxygenase, an enzyme with 4-hydroxyphenylpyruvate dioxygenase activity that binds iron and metal ions. In soybean, this gene is associated with plastoquinone, carotenoid, and vitamin E anabolism, as well as tyrosine and L-phenylalanine breakdown. It is linked to herbicide response, regeneration, and virus-induced post-transcriptional gene silencing. The encoded protein is localized to the cytoplasm, mitochondria, and extracellular space. Studies of the Arabidopsis relative PDS1 link the family to tocopherol biosynthesis, herbicide response, and chlorophyll retention, while sequence similarity connections associate the family with leaf necrosis, seed weight, seed size, protein content, and salt tolerance.
