摘要:

水稻产量形成依赖于源器官(叶)的光合生产能力、库器官(籽粒)的同化产物储存能力和流(维管束系统)的转运能力以及三者的协调,其调控受内在与环境因子的共同作用。近年来,随着生理生化、遗传和分子生物学研究手段的革新,研究者已逐步揭示水稻源器官发育、库容量构建及同化物转运的分子调控和互作机制及其对环境和栽培因素的响应机理。本文重点综述了源-流-库系统的形成及调控的生理和分子机理,总结了环境因子、激素信号转导和栽培技术对源-流-库的协同调控作用及产量形成的影响。最后指出了通过遗传改造、重要基因和蛋白挖掘及功能解析、激素互作机制和源-流-库动态协调网络解析等策略优化源流库关系来提高水稻产量的研究方向。

Abstract:

The formation of rice yield depends on the photosynthetic production capacity of the source organ (leaves), the storage capacity of assimilates in the sink organ (grains), the transport capacity of the flow (vascular bundle system), and the coordination of these three traits. Its regulation is influenced by both intrinsic and environmental factors. In recent years, with the innovation of physiological, biochemical, genetic, and molecular biology research methods, researchers have gradually revealed the molecular regulatory and interaction mechanisms underlying rice source organ development, sink capacity construction, and assimilate transport, as well as their response mechanisms to environmental and cultivation factors. This manuscript focuses on the physiological and molecular mechanisms of the formation and regulation of the source-flow-sink system and explores the synergistic regulatory effects of environmental factors, hormone signal transduction, and cultivation techniques on this system and yield formation. Finally, several research directions are proposed to improve rice yield by optimizing the source-flow-sink relationship through strategies such as genetic modification, mining and functional analysis of key genes and proteins, investigation of hormone interaction mechanisms, and dynamic coordination network analysis of the source-flow-sink system.
