摘要

荞麦(Fagopyrum spp.)是一种典型的假谷物,因其广泛的营养保健潜力和数百年的种植历史而备受重视。鞑靼荞麦和普通荞麦由于含有大量蛋白质、类黄酮和矿物质,已在全球广泛使用,并成为著名的营养食品。此外,对荞麦的需求日益增加,因此提高荞麦的营养价值、性状和产量至关重要。本综述根据荞麦的化学结构、特性和生理功能,对荞麦中积累的生物活性化合物进行了全面评估。通过对类黄酮生物合成的调控,有条不紊地总结了类黄酮、酚酸和苦荞素的生物合成途径。虽然前人的研究已经提出了经典的合成途径,但这些化合物在荞麦中合成的代谢流程仍未被揭示。通过多组学研究,确定了参与黄酮醇生物合成、胁迫响应和植物发育的功能基因。此外,该研究还深入探讨了多组学在改善荞麦农艺性状方面的应用,包括:产量、营养成分、抗逆性和生物活性化合物的生物合成。庞基因组学与其他全局组学相结合挖掘精英基因、特定农艺性状和生物活性成分生物合成的调控网络和机制,以及为基因工程开发更高效的遗传转化系统,这些都需要进一步研究,以实施旨在提高荞麦理想性状的育种设计。这篇重要综述将使人们全面了解多组学技术在荞麦营养保健和性状改良方面的应用。

Advancements in multi-omics for nutraceutical enhancement and traits improvement in buckwheat.

Buckwheat (Fagopyrum spp.) is a typical pseudocereal, valued for its extensive nutraceutical potential as well as its centuries-old cultivation. Tartary buckwheat and common buckwheat have been used globally and become well-known nutritious foods due to their high quantities of: proteins, flavonoids, and minerals. Moreover, its increasing demand makes it critical to improve nutraceutical, traits and yield. In this review, bioactive compounds accumulated in buckwheat were comprehensively evaluated according to their chemical structure, properties, and physiological function. Biosynthetic pathways of flavonoids, phenolic acids, and fagopyrin were methodically summarized, with the regulation of flavonoid biosynthesis. Although there are classic synthesis pathways presented in the previous research, the metabolic flow of how these certain compounds are being synthesized in buckwheat still remains uncovered. The functional genes involved in the biosynthesis of flavonols, stress response, and plant development were identified based on multi-omics research. Furthermore, it delves into the applications of multi-omics in improving buckwheat's agronomic traits, including: yield, nutritional content, stress resilience, and bioactive compounds biosynthesis. While pangenomics combined with other omics to mine elite genes, the regulatory network and mechanism of specific agronomic traits and biosynthetic of bioactive components, and developing a more efficient genetic transformation system for genetic engineering require further investigation for the execution of breeding designs aimed at enhancing desirable traits in buckwheat. This critical review will provide a comprehensive understanding of multi-omics for nutraceutical enhancement and traits improvement in buckwheat.
