F3H — Glycine max

Summary

GmF3H (GLYMA_01G166200V4) encodes a protein with a DIOX_N domain and an Oxoglu/Fe-dep_dioxygenase_dom, and has flavanone 3-dioxygenase, flavonol synthase, chalcone isomerase, and 2-oxoglutarate dioxygenase activities, and binds vitamin C and metal ions. In soybean, this gene is associated with flavonoid metabolism, pigmentation, UV protection, seed coat development, regeneration, nitrogen fixation, isoflavonoid anabolism, coumarin anabolism, and other biological processes. It is linked to traits including flower color, seed coat color, seed size, seed longevity, protein content, plant height, root length, heterosis, cytoplasmic male sterility, UV-B light sensitivity, oxidative stress response, and salt tolerance. Additional associations include proanthocyanidin accumulation, flavonoid synthesis, UV-B radiation tolerance, circadian clock regulation, photosynthetic activity, cold acclimation, and pathogen response. Studies of related genes in other species link the family to anthocyanin accumulation, UV-B tolerance, seed coat pigmentation, and flavonol synthesis.
