Construction of a Multi-Omics database for Paeonia lactiflora: A resource for comprehensive data integration and analysis

Abstract

Background

Paeonia lactiflora Pall. is a traditional medicinal plant widely used in East Asia, particularly for its roots, which are processed into various herbal remedies. With the advancement of omics technologies, significant genomic, transcriptomic, proteomic, and metabolomic data related to P. lactiflora have been generated. To facilitate the utilization of this wealth of information for research and applications, a multi-omics database specific to P. lactiflora was developed.

Results

This comprehensive multi-omics database includes genomic, transcriptomic, and proteomic datasets, as well as chemical compound profiles identified in various tissues and growth stages. The database also features data on key biosynthetic pathways, including those associated with monoterpenoid glycosides such as paeoniflorin, and provides tools for analyzing protein structures and interactions. Additionally, it summarizes P. lactiflora’s major active compounds, and highlights reported pharmacological effects. The database is organized into key functional modules: Home, Genome, Transcriptome, Proteome, Tools, Biosynthetic Pathways, Chemical Compounds, and Publications. Notably, the “Tools” module supports sequence alignment, pathway enrichment analysis (including Kyoto Encyclopedia of Genes and Genomes, KEGG), protein structure prediction, and primer design.

Conclusions

The multi-omics database (URL: http://210.22.121.250:8888/cosd/home/indexPage) of P. lactiflora integrates extensive molecular and chemical data, providing a robust platform for researchers. It serves as a valuable resource for advancing studies on the cultivation, breeding, and molecular pharmacognosy of P. lactiflora and supports the development of its medicinal applications.

Background

Paeonia lactiflora Pall., commonly known as the Chinese peony, is a perennial herbaceous plant belonging to the family Paeoniaceae. It is widely distributed across China, Korea, Japan, and eastern Russia and is one of the representative species of the genus Paeonia [1, 2]. Known for its strikingly beautiful flowers, P. lactiflora is often referred to as the “Prime Minister of Flowers,” a title that highlights its aesthetic appeal and profound cultural significance [3]. As early as the 6th century BCE, peonies were mentioned in The Book of Songs, China’s earliest collection of poetry, where they symbolized beauty and love, becoming a prominent motif in ancient literature and art [4]. Beyond its ornamental value, the P. lactiflora holds an irreplaceable role in traditional Chinese medicine (TCM), with its medicinal use traceable to Sheng Nong’s herbal classic, the first pharmacological text in China [5]. In Shanghan Lun (Treatise on Cold Damage Diseases) by Zhang Zhongjing, a classic TCM book, formulas containing P. lactiflora account for one-third of all prescriptions, underscoring the plant’s importance in traditional medicine [6]. The root of P. lactiflora is its primary medicinal component, which can be processed into two main forms: Bai Shao (Radix Paeoniae Alba) and Chi Shao (Paeoniae Radix Rubra). Modern pharmacological studies have revealed the chemical composition and bioactivity of P. lactiflora roots, which are rich in monoterpenes, glycosides, and flavonoids [7–9]. Among these, paeoniflorin, a key bioactive compound, has been demonstrated to possess significant analgesic, anti-inflammatory, and immunomodulatory effects [10–12]. These properties make P. lactiflora not only a vital resource in traditional medicine but also a promising candidate for modern drug development, providing invaluable resources for contemporary medical research.

The family Paeoniaceae is unique in the plant kingdom as it contains only one genus, Paeonia, comprising approximately 30 species [13]. Many species are cultivated extensively for their ornamental value due to their uniquely beautiful flowers [14]. To date, researchers and horticulturists have successfully developed over 8,000 cultivars, primarily derived from hybridization among more than 30 wild species, and this number continues to grow [15]. These abundant cultivars not only cater to the demands of the horticultural market but also serve as crucial resources for botanical and genetic research. However, despite the evident ornamental and medicinal value of peonies, the utilization of their genetic resources remains challenging [16]. To facilitate genome-assisted breeding and cultivar improvement, the development of high-quality reference genomes for wild peony species has become imperative. Although paeoniflorin is the primary bioactive compound in P. lactiflora, its biosynthetic pathway remains incompletely elucidated, and the associated key genes are yet to be identified [17]. Addressing these knowledge gaps requires the support of comprehensive and high-quality genomic data. In recent years, advances in genome sequencing technology have overcome many technical bottlenecks in constructing high-quality genomes [18, 19]. To date, several species within the family Paeoniaceae have had their genomes successfully sequenced, including P. ludlowii, P. ostii, and P. suffruticosa [20–22]. Building on these advancements, our laboratory conducted a whole-genome sequencing project for P. lactiflora. The results reveal that approximately 11.4 Gb of genomic sequences were anchored to five chromosomes, comprising 2,408 contigs. This high-quality genomic dataset establishes a solid foundation for studying the functional genes of P. lactiflora and advancing its genetic improvement, while also providing critical data for decoding the biosynthetic pathways of representative monoterpenes produced by P. lactiflora.

In modern life sciences, the acquisition and analysis of large-scale, complex data have consistently posed significant challenges [23, 24]. With the rapid expansion of bioinformatics technologies, the efficient storage, integration, and visualization of such data have become essential tasks for researchers. Online databases, known for their integrative and convenient nature, have become indispensable tools in life sciences research [25, 26]. For instance, online databases for Arctium lappa and Myrica rubra have greatly facilitated research and applications related to these species [27, 28]. Such successful models offer valuable insights for developing databases for other economically and medicinally important plants. To further explore the biosynthetic pathway of paeoniflorin and its ecological functions, we performed comprehensive multi-omics analyses—including transcriptomics, proteomics, and metabolomics—on the roots, stems, and leaves of P. lactiflora samples. By integrating multi-omics data with genomic information, we constructed a powerful P. lactiflora database. This database incorporates a genome browser, sequence alignment tools, homologous protein prediction, and primer design functionalities, providing researchers with an efficient platform for data retrieval. For example, 3-hydroxy-3-methyl glutaryl coenzyme A (HMG-CoA) reductase, which catalyzes the rate-limiting step of the mevalonate pathway by reducing HMG-CoA to mevalonic acid, serves as the pivotal enzyme in the mevalonate pathway [29]. Our database contains five distinct HMG-CoA reductase genes that can be effectively retrieved, demonstrating its practical utility for investigating the biosynthetic pathway of paeoniflorin.

As global demand for medicinal plant resources continues to rise, the dual ornamental and medicinal value of P. lactiflora has made its research increasingly prominent. The establishment of this database enables researchers to systematically study the genetic characteristics, gene expression, and functional proteins of peonies. This will accelerate the breeding of new cultivars and the application of functional genes. Additionally, these research outcomes will provide novel molecular targets and scientific foundations for modern drug development, further advancing the modernization of traditional Chinese medicine.

Conclusion

The database is publicly accessible at http://210.22.121.250:8888/cosd/home/indexPage. Our team is committed to its long-term maintenance. This study aims to provide a comprehensive storage platform for P. lactiflora-related data. It is an intelligent, interactive, and user-friendly system that enables researchers and practitioners to browse, search, and retrieve relevant and valuable information. The database facilitates genomic, transcriptomic, proteomic, and metabolomic research on P. lactiflora.

In particular, the database offers key resources to support investigations into the biosynthetic pathways of bioactive compounds, such as paeoniflorin. Although the overall biosynthetic route of paeoniflorin remains incompletely elucidated, several functionally relevant enzymes have been identified. For instance, in the terpenoid biosynthesis pathway, farnesyl pyrophosphate synthase (FPS) plays a crucial role by catalyzing the condensation of geranyl pyrophosphate (GPP) and isopentenyl pyrophosphate (IPP) to produce farnesyl pyrophosphate (FPP)—a key branching point for the synthesis of sesquiterpenes and triterpenes. This enzymatic step is of central importance to understanding plant secondary metabolism and advancing natural product development [32]. Our database provides access to three FPS genes in P. lactiflora, allowing researchers to systematically explore their regulatory roles in paeoniflorin biosynthesis.

Moreover, downstream modification processes are also partially characterized. Notably, PoDPBT, a BAHD-family O-benzoyltransferase, has been experimentally validated to catalyze the benzoylation of 8-debenzoylpaeonidin to produce paeoniflorin, marking it as the first functional enzyme identified in the modification phase of the paeoniflorin pathway [33]. To further support pathway elucidation, the database includes three additional BAHD-family genes predicted to be involved in similar modification steps, offering a valuable foundation for future functional studies.

Despite these advances, major gaps remain. The mechanism underlying the formation of paeoniflorin’s characteristic hemiketal-acetal bond is still unknown and likely involves a series of yet-uncharacterized enzymatic reactions. Through its specialized modules, our platform enables the identification and retrieval of candidate genes that may participate in these processes, thereby accelerating functional characterization and pathway reconstruction.

While the P. lactiflora database provides a valuable and integrative resource, we acknowledge several limitations in its current iteration. First, the data coverage is not yet exhaustive. Although the platform includes whole-genome sequencing data, there are gaps in annotation quality and consistency. Some entries currently lack comprehensive functional annotations or contextual metadata, which may limit interpretability for certain users. Second, with regard to update frequency, we strive to keep the platform timely and relevant, but it may not always reflect the most recent discoveries or datasets in real time. Third, as the volume and complexity of biological data continue to grow exponentially, the long-term scalability of our existing infrastructure and data model requires ongoing evaluation and optimization. We are actively working to address these limitations. Future development efforts will focus on expanding data coverage, enhancing annotation depth through manual curation and the integration of emerging knowledge sources, and increasing the frequency and automation of updates. Importantly, user feedback will play a crucial role in guiding these improvements, ensuring that the database continues to meet the evolving needs of the research community.

Materials and methods

The genomic data incorporated into the P. lactiflora database were sourced from wild specimens (coordinates: 118.2826°E, 41.6225°N) collected in Meilin Town, Chifeng City, Inner Mongolia Autonomous Region, China, during 2023 under official permission from the Meilin Town Government. These specimens were field-collected by Dr. Rongchun Han and deposited in the Herbarium of Anhui University of Chinese Medicine (Voucher No. 231010PL003). In parallel, the proteomic and metabolomic datasets originated from cultivated samples (coordinates: 117.3875°E, 31.9406°N) harvested in 2024 at Anhui University of Chinese Medicine, Hefei City, Anhui Province, China, with formal approval from the Academic Committee of Anhui University of Chinese Medicine. The latter specimens, acquired by Mr Zongran Lu, were preserved in the same repository (Voucher No. 241215PL009). All botanical materials were taxonomically authenticated by Dr. Rongchun Han. The precise decimal degrees coordinates are provided to ensure reproducibility of specimen collection for ecological studies, accurate documentation of germplasm provenance in genetic resource databases.

Whole-genome sequencing was performed using the PacBio Revio platform (Pacific Biosciences, USA; https://www.pacb.com), which utilizes Single Molecule Real-Time (SMRT) sequencing technology. Genome assembly was carried out using a combination of tools, including Hifiasm v0.19.5, minimap2 v2.21, and 3D-DNA (version 180922), while genome annotation was conducted with software such as BLAST v2.11.0+, MAKER v3.01.03, DIAMOND v2.0.7, and RNAmmer v1.2. Proteomic profiling was performed via nano-liquid chromatography coupled with a timsTOF Pro mass spectrometer operated in diaPASEF mode. Quantitative analysis of the proteomic data was conducted using DIA-NN (library-free mode), referencing a P. lactiflora protein sequence dataset from UniProt. Identified proteins were functionally annotated and analyzed for pathway enrichment using databases including GO, KEGG, and Pfam. Metabolomic profiling was performed using liquid chromatography–tandem mass spectrometry (LC-MS/MS) to provide a comprehensive characterization of metabolite composition.

The P. lactiflora database is deployed on the Ubuntu 16.04 operating system and developed using AKKA 2.6.5 (web server), MySQL 5.7 (database server), Scala 2.13.2, and SBT 13.9. All data in the database are managed and stored by the MySQL database management system. The query functionality is implemented using the Slick 3.3.2 middleware layer. For genome visualization, we utilize JBrowser 1.12.3. The website interface components are designed and implemented using Bootstrap 4.6.0 and Play Framework 2.8.7.
