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.

发现具有额外小穗和增加谷物产量的面包小麦突变体

面包小麦 (Triticum aestivum L.) 的谷物产量很大程度上取决于穗结构。编码 AP2/ERF 蛋白的 DUO-B1 中的突变导致具有额外小穗的穗结构，从而增加了每个穗的粒数和田间条件下的产量。转基因 DUO-B1 具有增加谷物产量的潜力。
