Abstract

The Corydalis genus, one of the largest within the Papaveraceae family, holds a rich diversity of medicinal resources, particularly among its tuberous species. Benzylisoquinoline alkaloids (BIAs) are primarily responsible for the medicinal properties observed in Corydalis plants. In this study, we conducted an integrated evolutionary analysis by combining whole-genome resequencing with comprehensive metabolite profiling across various Corydalis species. Guided by these initial findings, supported by local cultivation practices and an extensive literature review, we further investigated six tuberous Corydalis species: C. yanhusuo, C. decumbens, C. schanginii, C. ledebouriana, C. solida, and the newly identified C. nanchuanensis. Our results revealed conserved alkaloid profiles across these species but highlighted significant variations in key bioactive compounds. Notably, C. nanchuanensis exhibited considerably higher levels of tetrahydropalmatine compared to the commonly used medicinal species C. yanhusuo, while C. solida, originally sourced from the Netherlands, displayed elevated concentrations of corydaline, palmatine, and dehydrocorydaline. Additionally, transcriptome-metabolome correlation analyses pinpointed several critical genes involved in protopine biosynthesis, particularly emphasizing the TNMT gene family. These discoveries significantly enhance our understanding of metabolic diversity in tuberous Corydalis, providing essential insights for the exploration of novel medicinal resources and facilitating targeted genetic improvements for therapeutic use.

代谢组学和进化整合揭示了六种延胡索属植物的药用潜力。
紫堇属,罂粟科中最大的一个,拥有丰富多样的药用资源,特别是在其块茎物种中。苯基异喹啉生物碱(Benzylisoquinoline alkaloids, BIAs)是延胡索属植物的主要药用成分。在这项研究中,我们通过将全基因组重测序与综合代谢物分析相结合,对不同延胡索属物种进行了综合进化分析。在这些初步发现的基础上,结合当地的栽培实践和广泛的文献综述,我们进一步研究了6个块茎延胡索(C. yanhusuo)、C. decumbens、C. changinii、C. ledebouriana、C. solida和新发现的C. nanchuanensis。我们的研究结果揭示了这些物种中保守的生物碱谱,但突出了关键生物活性化合物的显著差异。值得注意的是,与常用药用品种延湖梭相比,南川梭含有更高水平的四氢巴马汀,而原产于荷兰的南川梭含有较高浓度的堇青碱、巴马汀和脱氢堇青碱。此外,转录组-代谢组相关分析确定了几个参与原嘌呤生物合成的关键基因,特别强调了TNMT基因家族。这些发现极大地增强了我们对块茎延胡索代谢多样性的认识,为探索新的药用资源和促进治疗用途的靶向遗传改进提供了重要的见解。

期刊介绍: Aims Molecular Horticulture aims to publish research and review articles that significantly advance our knowledge in understanding how the horticultural crops or their parts operate mechanistically. Articles should have profound impacts not only in terms of high citation number or the like, but more importantly on the direction of the horticultural research field. Scope Molecular Horticulture publishes original Research Articles, Letters, and Reviews on novel discoveries on the following, but not limited to, aspects of horticultural plants (including medicinal plants): ▪ Developmental and evolutionary biology ▪ Physiology, biochemistry and cell biology ▪ Plant-microbe and plant-environment interactions ▪ Genetics and epigenetics ▪ Molecular breeding and biotechnology ▪ Secondary metabolism and synthetic biology ▪ Multi-omics dealing with data sets of genome, transcriptome, proteome, metabolome, epigenome and/or microbiome. The journal also welcomes research articles using model plants that reveal mechanisms and/or principles readily applicable to horticultural plants, translational research articles involving application of basic knowledge (including those of model plants) to the horticultural crops, novel Methods and Resources of broad interest. In addition, the journal publishes Editorial, News and View, and Commentary and Perspective on current, significant events and topics in global horticultural fields with international interests.
