YUC — Brachypodium distachyon

Summary

BdYUC (BRADI_4G40770V3) encodes a flavin-containing monooxygenase with indole-3-pyruvate monooxygenase activity (EC 1.14.13.168) and is associated with auxin biosynthesis in Brachypodium distachyon. The gene is associated with IAA biosynthetic processes, regulation of auxin biosynthesis, and multiple developmental programs including leaf, root, floral meristem, inflorescence, and cotyledon development. BdYUC has been linked to drought recovery, regeneration, response to oxidative stress, cytokinin, herbicides, and metals. The encoded protein localizes to the endoplasmic reticulum, Golgi membrane, cytosol, mitochondria, and extracellular space. Associations with IAA content and phenotypes such as seed size, shoot branching, lateral root formation, anther dehiscence, senescence, and heavy metal stress tolerance have been reported. Related genes in other species link the YUCCA family to drought tolerance, oxidative stress tolerance, phototropism, pollen development, and grain traits.
