YUC — Brachypodium distachyon

Summary

BdYUC (BRADI_2G04257V3) on chromosome 2 of Brachypodium distachyon encodes a flavin-containing monooxygenase with indole-3-pyruvate monooxygenase activity (EC 1.14.13.168), placing it in the auxin biosynthesis pathway. The gene is associated with IAA biosynthetic and regulatory processes, and is linked to drought recovery, regeneration, floral meristem determinacy, and responses to cytokinin, oxidative stress, and herbicides. It is associated with regulation of leaf, root, and inflorescence development, as well as embryogenesis and cotyledon development. The product localises to the ER, Golgi, mitochondria, and cytosol. Associations with IAA content, seed size, shoot branching, lateral root formation, senescence, and heavy metal stress tolerance have been reported. Studies of related genes in other species link the family to traits including inflorescence size, floret number, aluminium tolerance, and photoperiod sensitivity.
