YUC — Brachypodium distachyon

Summary

BdYUC (BRADI_2G10302V3) on Brachypodium distachyon chromosome 2 encodes a flavin-containing monooxygenase with indole-3-pyruvate monooxygenase activity (EC 1.14.13.168), central to auxin biosynthesis. The gene is associated with IAA biosynthetic and regulatory processes, morphogenesis, leaf and root development, floral meristem determinacy, inflorescence development, embryogenesis, regeneration, drought recovery, and responses to oxidative stress, cytokinin, herbicide, and metals. It localizes to the ER, Golgi, cytosol, mitochondria, and extracellular space. Associations include IAA content, seed size, shoot branching, lateral root formation, anther dehiscence, pollen maturation, senescence, and tolerance to heavy metal, alkaline salinity, and nickel stress. Studies of related genes in other species link the family to floret number, inflorescence size, spikelet fertility, grain traits, photoperiod sensitivity, and drought tolerance.
