AGL2 — Brachypodium distachyon

Summary

BdAGL2 (BRADI_3G41260V3) on Brachypodium distachyon chromosome 3 encodes a MADS-box transcription factor with DNA-binding, transcription regulator, and coactivator/corepressor activities, as well as histone demethylase and ATP hydrolase functions. The gene is associated with regulation of proanthocyanidin anabolism, abscisic acid breakdown, cellular water homeostasis, and responses to osmotic stress and biotic stimuli. It has been linked to negative regulation of seed maturation, release of seed from dormancy, regulation of double fertilization forming a zygote and endosperm, fruit abscission, and negative regulation of floral organ abscission. Associations with traits include seed coat hardness and color, floral organ size and morphology, leaf shattering, fruit ripening, plant height, and photoperiod-sensitive flowering time. The protein localizes to the nucleus, cytoplasm, plastid, plasmodesma, and chromatin-remodeling complexes. Studies of related genes in other species link the family to floral organ identity, seed development, heading date, and stress tolerance.
