[摘要]
黑果枸杞Lycium ruthenicum为我国西北特殊生境地区食药兼用的生态经济植物,其浆果富含花色苷、花青素、多酚、多糖等物质,是医药保健品、食品添加剂(天然色素)的主要成分和原料。随着测序技术和各组学学科的不断发展,组学技术已被广泛应用于黑果枸杞资源的各项研究中,尤其从单一的基因组、转录组、代谢组、蛋白质组到多组学联合分析,对黑果枸杞品质评价、耐盐碱、果实发育机制以及花青素合成与积累等研究更加深入。综述了近年来组学技术在黑果枸杞资源综合评价、抗逆、次生代谢物生物合成代谢调控中的应用,探讨了资源品质差异成因和生态环境适应机制,为黑果枸杞资源的保护、种质创新及合理开发利用提供科学依据。

[Abstract]
Lycium ruthenicum is an edible and medicinal fruit tree, which widely distributes in the arid desert and saline-alkali region of Northwest China. L. ruthenicum berries have rich secondary metabolites (such as anthocyanins, anthocyanidins, polyphenols, and polysaccharides) and high economic and ecological values, which were widely used in the field of nutritional foods, biochemical drugs, and food additives. With the continuous development of sequencing technology and omics, omics technology (genomics, transcriptomics, proteomics, and metabolomics) and integrative multi-omics approach have become important means for the research of L. ruthenicum resources (especially in the areas of quality evaluation, saline-alkali resistance, fruit development, and synthesis and accumulation of anthocyanins). The application of omics in recent years in comprehensive evaluation of L. ruthenicum, stress resistance, and biosynthesis and regulation of secondary metabolites was reviewed in this paper. The causes of differences in the L. ruthenicum resource quality and ecogeographic adaptation mechanism were also investigated, which provide scientific basis for the L. ruthenicum conservation, germplasm improvement and innovation and rational development and utilization of L. ruthenicum.
