ABI3 — Brachypodium distachyon

Summary

BdABI3 (BRADI_2G58390V3) on Brachypodium distachyon chromosome 2 encodes a B3 DNA-binding domain protein with transcription coactivator activity, sequence-specific DNA binding, and protein dimerization activity. It is associated with positive regulation of seed maturation, cellular response to gibberellin stimulus, regulation of triglyceride catabolic process, and far-red signaling. The gene is linked to seed set percent, seedling vigor, vegetative vigor, photoperiod sensitivity, water stress response, temperature stress response, and iron content. It has been connected to seed dormancy, drought stress response, lateral root formation, and endosperm development. Studies of related genes in other species link the family to seed longevity, abscisic acid responsiveness, oil accumulation, iron distribution in seed, vivipary, and leaf angle.
