Medicinal Plant Research 2025, Vol.15, No.3, 142-150 http://hortherbpublisher.com/index.php/mpr 147 the identification of high-performing germplasm with high-quality traits. Pan-genomics facilitates the cataloging of variable and core genes, which are of good use in the development of high-resolution molecular markers such as SSRs. The markers are vital during variety registration, germplasm characterization, and marker-assisted selection in breeding programs (Hur et al., 2021; Moghaddam et al., 2023). These materials assist in accelerating selection and protection of improved Astragalus lines. 6.2 Improvement of medicinal components and quality consistency control The pan-genome provides an accurate map of gene families and structural variations engaged in the biosynthesis of key bioactive molecules like triterpenoids and flavonoids. This data enables specific breeding and genetic enhancement to generate high bioactive content and consistent quality. With the knowledge of the genetic determinants of metabolic pathways, breeders can select lines for uniform and high levels of pharmacologically active metabolites that facilitate the standardization of traditional Chinese medicine products (Chen et al., 2022; Shi et al., 2022). 6.3 Enhancement of stress-resistance traits and ecological adaptability Pan-genomic studies-uncovered variable genes are usually enriched in biotic and abiotic stress-resistance functions. The results are beneficial for breeding Astragalus cultivars with increased environmental stress and pathogen tolerance. Pan-genomic information coupled with phenotypic and ecological information facilitate the development of cultivars for varied and changing environments to meet sustainable production (Bayer et al., 2020; Chang et al., 2021). 6.4 Pan-genome-enabled precision development of traditional chinese medicine Pan-genomics also offers a new reference platform for precision breeding and modernization of traditional Chinese medicine. By linking structural and sequence variation to phenotypic traits and medicinal quality, pan-genome resources enable the rational design of Astragalus cultivars for target therapeutic uses. Integration of pan-genomic data with metabolomics and transcriptomics also enables precision development and quality control of herbal medicines (Jayakodi et al., 2021). 7 Interdisciplinary Integration and Application Expansion of Pan-genomics in Astragalus 7.1 Integration of pan-genomics with multi-omic Integrating pan-genomics with multi-omics approaches—i.e., metabolomics, epigenomics, and transcriptomics-allows for a comprehensive understanding of genetic diversity, gene regulation, and metabolic networks. Integration unveils novel aspects of genome complexity, relates genetic diversity to phenotypic traits, and facilitates the identification of regulatory elements and metabolic pathways in medicinal quality and adaptation. Multi-omics approaches like these are increasingly important for deciphering the functional effects of pan-genomic variation in plants and other species. 7.2 Combination with systems biology and network pharmacology Pan-genomics coupled with systems biology and network pharmacology allows one to reconstruct gene regulatory and metabolic networks. It is by virtue of this inter-disciplinary approach that one can model intricate biological processes, predict the function of genes, and unveil significant nodes of pharmacological routes. Such information is significant for understanding the all-encompassing influence of genetic variance on crop traits and for rational drug design and discovery (Reghu et al., 2024). 7.3 Applications of big data and artificial intelligence in gene function analysis The genomic flood requires advanced computational strategies. Artificial intelligence (AI) and big data analytics and machine learning models are increasingly utilized currently to pan-genomic datasets in predicting gene function, genome mining, and discovery of new biosynthetic gene clusters. These enhance functional annotation in terms of speed and accuracy and accelerate identification of genes linked to important traits and medicinal attributes (Kloosterman et al., 2020; Liu et al., 2022).
