种子代谢物对植物发育和人类营养都是至关重要的；然而，它们水平的自然变化仍然没有得到充分的表征。在这里，我们分析了水稻品种和水稻品种成熟种子中的121种代谢产物，揭示了水稻种子的代谢表型和地理来源之间的相关性。此外，不仅在代谢产物的相对丰度上，而且在相应的代谢联合网络上，水稻亚种和水稻亚种也存在显著差异。这些发现为研究水稻亚群的代谢适应提供了重要的见解，弥合了基因组和物候组之间的差距，并有助于识别代谢特性的遗传控制，为未来通过代谢工程改善水稻品质奠定了基础。
Seed metabolites are critically important both for plant development and human nutrition; however, the natural variation in their levels remains poorly characterized. Here we profiled 121 metabolites in mature seeds of a wide panel Oryza sativa japonica and indica cultivars, revealing correlations between the metabolic phenotype and geographic origin of the rice seeds. Moreover, japonica and indica subspecies differed significantly not only in the relative abundances of metabolites but also in their corresponding metabolic association networks. These findings provide important insights into metabolic adaptation in rice subgroups, bridging the gap between genome and phenome, and facilitating the identification of genetic control of metabolic properties that can serve as a basis for the future improvement of rice quality via metabolic engineering.
