Abstract:

Plant Cell Culture (PCC) has emerged as a highly promising synthetic biology chassis, offering a range of advantages such as short growth cycles, cost-effectiveness, absence of pathogenic risks, and abundant secondary metabolites. These features make PCC an attractive alternative option for applications in medicine, food, and health. However, insufficient production efficiency due to difficulties in genetic transformation, complex regulatory networks, cell aggregation, and poor genetic stability remains a major obstacle, limiting the commercialization of PCC. Synthetic biology, with its bottom-up engineering design approach, provides a powerful toolkit to address these challenges. By enabling the precise design and modification of native plant cells, synthetic biology offers innovative strategies to develop efficient and economically viable plant cell factories. In this paper, we first review the current status of PCC in synthesizing high-value compounds, particularly recombinant proteins and secondary metabolites. Recent advancements have demonstrated the potential of PCC to produce therapeutic proteins, vaccines, and industrial enzymes, as well as bioactive compounds such as alkaloids, flavonoids, and terpenoids. These successes underscore the versatility of PCC as a bioproduction platform. We then explore the role of synthetic biology in advancing PCC industrialization. Key developments include the creation of high-quality plant cell lines through genome editing tools like CRISPR/Cas9, enhancing genetic stability and metabolic efficiency. Additionally, synthetic biology has improved genetic transformation systems, overcoming a critical bottleneck in PCC. Enhanced expression systems, incorporating synthetic promoters and regulatory elements, have significantly boosted target compound yields. Furthermore, synthetic biology has expanded PCC applications by enabling the biosynthesis of heterologous compounds beyond their native metabolic pathways. Finally, we discuss future prospects, emphasizing the potential of synthetic biology to overcome current technical challenges. Emerging technologies such as multi-omics integration, machine learning, and synthetic organelle development are expected to further enhance PCC's scalability and efficiency. By addressing these challenges, synthetic biology will pave the way for large-scale plant cell cultivation, facilitating its widespread adoption in industrial bioproduction. The convergence of PCC and synthetic biology holds immense potential for sustainable, cost-effective, and scalable production of high-value compounds.

摘要:

植物细胞培养(Plant cell culture, PCC)作为一种极具发展潜力的生物合成平台,具有生长周期短、成本效益高、无病源危害、次生代谢产物丰富等优势,在医药、食品和保健等领域备受关注。然而,生产效率不足是限制PCC应用于商业化生产的最大阻碍,问题在于遗传转化困难、调控网络复杂、细胞结团及遗传稳定性差。合成生物学遵循自下而上的工程化建造理念,对天然植物细胞进行精准设计与改造,为开发高效、经济可行的植物细胞工厂提供了新的解决方案。本文首先回顾了PCC作为合成平台在生产重组蛋白和次生代谢产物中的研究现状。重点探讨了植物合成生物学对PCC的工业化发展中的推动作用,包括优质植物细胞系的构建、遗传转化体系的优化、表达系统的优化、生产效率与产能的提升以及赋予植物细胞合成异源产物的能力。最后,本文对PCC未来的发展前景进行了展望,强调了合成生物学理念和技术在突破当前技术瓶颈中的关键作用,为植物细胞大规模培养的进一步发展指明了方向。
