我们的生活依赖于极少数谷物品种，它们的谷物为我们的饮食提供了比任何其他来源更多的卡路里。种植谷物的非凡生产力反映了数千年的选择、最近的定向育种和现代农业实践。在这里，我们研究了谷物主要身体部分的选定的建筑和农艺特征：叶、枝、花序、茎和根；并讨论了它们的操纵如何提高作物的表现。强调实验室模型和田间系统的协同研究，我们考虑了多样化的分子电路、新颖的调节器以及遗传、激素和分子机制的保守成分如何控制谷物的结构。最后，我们强调了谷物生长过程中发展决策的农业重要性，并提出了未来稳健建筑改进的前景，这一点因我们日益加剧的气候危机而变得更加紧迫。
Our lives depend on an incredibly small number of cereal species whose grain provides more calories to our diet than any other source. The extraordinary productivity of cultivated cereals reflects millennia of selection, recent directed breeding, and modern agricultural practices. Here, we examine selected architectural and agronomic features of major cereal body parts: leaf, branch, inflorescence, stem and root; and discuss how their manipulation enhanced crop performance. Highlighting synergistic research across laboratory models and field-based systems, we consider how diversified molecular circuitry, novel regulators and conserved components of genetic, hormonal and molecular mechanisms control cereal architecture. Lastly, we emphasise the agricultural importance of developmental decisions during cereal growth and propose future perspectives for robust architectural improvement, made ever more urgent by our accelerating climate crisis.
