AIN1 — Brachypodium distachyon

Summary

BRADI_3G43000V3 (AIN1, also known as BdPLATZ1 or BdPLATZ2) 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 mitochondria and the nucleus. AIN1 is associated with ethylene sensitivity and response, ABA sensitivity, root and hypocotyl elongation, leaf senescence, gravitropic response, and desiccation tolerance in seeds and vegetative tissues. Studies of related genes in other species connect the PLATZ family to grain size, length, weight, and appearance, as well as yield, anthesis time, drought and cold tolerance, stomatal traits, quantum yield, and root morphology.
