AAT — Brachypodium distachyon

Summary

BdAAT (BRADI_2G04860V3) on Brachypodium distachyon chromosome 2 encodes a pyridoxal phosphate-dependent aminotransferase with multiple transaminase activities, including kynurenine-oxoglutarate, methionine-oxo-acid, and L-aspartate:prephenate transaminase activity, as well as 1-aminocyclopropane-1-carboxylate synthase activity. The gene is associated with inhibition of IAA biosynthetic process, negative regulation of ethylene biosynthetic process, shade avoidance, C4 photosynthesis, L-phenylalanine anabolism, auxin anabolism, ethylene anabolism, systemic acquired resistance, salicylic acid mediated signaling pathway, fruit ripening, and embryo development ending in seed dormancy. Its product localizes to the amyloplast membrane, chloroplast stroma, mitochondria, and cytosol. Related genes in other species link the family to grain protein content, grain weight, yield, drought tolerance, and salinity stress response.
