Grain yield in bread wheat (Triticum aestivum L.) is largely determined by spike architecture. Mutations in DUO-B1, encoding an AP2/ERF protein, result in a spike architecture with extra spikelets that increases both grain number per spike and yield under field conditions. Genetically modifying DUO-B1 has the potential to increase cereal production.
