Genetic engineering offers a promising approach to enhance the production of these valuable phytochemicals. For instance, sesquiterpenoids, which are known for their neuroprotective effects, can be produced in higher quantities through the manipulation of specific biosynthetic pathways (Si et al., 2021). Additionally, the identification of key genes involved in the synthesis of terpenoids and polyacetylenes provides targets for genetic modification to boost their production (Fang et al., 2022). The use of high-throughput RNA sequencing has revealed differentially expressed genes that could be manipulated to optimize the yield of these bioactive compounds (Fang et al., 2022). 7.2 Genomic tools for breeding and conservation The conservation and breeding of A. macrocephala can greatly benefit from genomic tools. Studies utilizing chloroplast DNA and microsatellites have shown that cultivated populations of A. macrocephala possess higher genetic diversity compared to their wild counterparts, which is crucial for breeding programs aimed at improving medicinal quality (Chen et al., 2018). Furthermore, the complete plastome sequence of A. macrocephala has been characterized, providing a comprehensive genetic resource that can be used for phylogenetic studies and the identification of molecular markers for breeding (Cai et al., 2020). Cryopreservation techniques, such as droplet-vitrification, have also been developed to conserve the genetic resources of A. macrocephala, ensuring the long-term preservation of its valuable germplasm (Zhang et al., 2015). 7.3 Potential for synthetic biology approaches Synthetic biology offers innovative strategies to harness the medicinal potential of A. macrocephala. By constructing synthetic pathways in microbial hosts, it is possible to produce complex phytochemicals in a controlled environment. The complete plastome and nuclear gene sequences of A. macrocephala provide a blueprint for the design of synthetic pathways (Cai et al., 2020; Wang et al., 2020). Additionally, the identification of molecular markers and the understanding of the genetic relationships among Atractylodes species can facilitate the development of synthetic biology approaches to produce specific bioactive compounds (Wang et al., 2020; Liu et al., 2022). The integration of genomic data with synthetic biology could lead to the scalable production of high-value phytochemicals, thereby enhancing the medicinal applications of A. macrocephala. In summary, the application of genetic engineering, genomic tools, and synthetic biology holds significant promise for enhancing the phytochemical production, breeding, conservation, and medicinal utilization of Atractylodes macrocephala. These biotechnological advancements can lead to the development of more effective and sustainable medicinal products derived from this valuable herb. 8 Future Perspectives and Research Directions 8.1 Gaps in current knowledge Despite significant advancements in understanding the medicinal properties and genetic makeup of Atractylodes macrocephala, several gaps remain. Firstly, while numerous bioactive compounds have been identified, the precise molecular mechanisms and structure-function relationships of these constituents are not fully understood (Zhu et al., 2018). Additionally, the potential synergistic and antagonistic effects among these compounds require further investigation (Zhu et al., 2018). The genetic diversity and population structure of A. macrocephala have been studied, but the impact of domestication on its genetic resources and the conservation of unique gene pools need more comprehensive analysis (Chen et al., 2018). Furthermore, the autotoxic effects of certain compounds on the plant's immune system and their broader ecological impacts are not well-documented (Zheng et al., 2018). 8.2 Emerging technologies and approaches Emerging technologies such as next-generation sequencing (NGS) and network pharmacology offer promising avenues for advancing our understanding of A. macrocephala. The complete plastome and chloroplast genome sequencing have already provided valuable insights into the genetic structure and phylogenetic relationships of
