AIN1 — Brachypodium distachyon

Summary

BRADI_3G34160V3 (BdAIN1) on chromosome 3 of Brachypodium distachyon encodes a PLATZ domain-containing protein that binds zinc and other proteins. The gene is associated with the GABA shunt, TCA cycle, fatty acid anabolism, sodium transport, cold acclimation, and homeostasis, and its product localises to both the nucleus and mitochondria. BdAIN1 is associated with ethylene sensitivity and response, ABA sensitivity, leaf senescence, root and hypocotyl elongation, gravitropic response, and desiccation tolerance (including seed and vegetative desiccation tolerance). Studies of related genes in other species link the PLATZ family to grain size, length, weight, and appearance, as well as yield, anthesis time, cold and drought tolerance, stomatal traits, quantum yield, and root morphology.
