目前，来源性状对于提高产量潜力具有重要意义；例如，人们正在花费大量精力寻找改变光合作用的方法。然而，光合作用只是作物调节的一个组成部分，因此必须以综合的系统方法考虑库活动和整个作物不同过程的协调。一组“接线图”被设计为一种可视化工具，用于整合小麦发育不同阶段的组件过程的相互作用。它们使叶绿体、叶子和整个冠层过程的作用能够在库发展和作物生长的整体背景下被看到。在这篇综述中，我们从解剖学上（叶面和非叶面）和时间上（花前和花后）剖析了源性状，并考虑了它们在局部和整株植物/作物水平上的调节证据。我们考虑树冠的形成如何为光合作用的组成部分带来挑战（自遮挡）和机遇（动态光合作用）。最后，我们讨论了反馈调节对源活动的调节。该综述是在接线图的框架内撰写的，接线图作为支撑谷物产量性状的综合描述符，旨在为育种者和其他作物科学家提供潜在的工作空间，连同高通量和精确的表型数据、遗传学和生物信息学，将有助于建立未来性状和基因相互作用的动态模型，以实现小麦和其他大田作物的增产。我们在“接线图”的背景下总结和更新了光合产物来源的起源和局限性，描绘了小麦生长和发育过程中的源和汇。
Source traits are currently of great interest for the enhancement of yield potential; for example, much effort is being expended to find ways of modifying photosynthesis. However, photosynthesis is but one component of crop regulation, so sink activities and the coordination of diverse processes throughout the crop must be considered in an integrated, systems approach. A set of ‘wiring diagrams’ has been devised as a visual tool to integrate the interactions of component processes at different stages of wheat development. They enable the roles of chloroplast, leaf, and whole-canopy processes to be seen in the context of sink development and crop growth as a whole. In this review, we dissect source traits both anatomically (foliar and non-foliar) and temporally (pre- and post-anthesis), and consider the evidence for their regulation at local and whole-plant/crop levels. We consider how the formation of a canopy creates challenges (self-occlusion) and opportunities (dynamic photosynthesis) for components of photosynthesis. Lastly, we discuss the regulation of source activity by feedback regulation. The review is written in the framework of the wiring diagrams which, as integrated descriptors of traits underpinning grain yield, are designed to provide a potential workspace for breeders and other crop scientists that, along with high-throughput and precision phenotyping data, genetics, and bioinformatics, will help build future dynamic models of trait and gene interactions to achieve yield gains in wheat and other field crops. We summarize and update the origins of and limitations to sources of photosynthate in the context of a ‘wiring diagram’, depicting source and sink within wheat growth and development.
