摘要:

合成生物学是汇聚了工程学和生物学的新兴交叉学科,近年来逐步在植物研究领域中显现其重要作用。利用合成生物学技术不仅可以对作物的产量及营养品质性状进行精准的改良和优化,还有望将植物改造成高价值的植物天然产物生产工厂满足人们更多的需求。本文从DNA合成与组装、植物基因编辑技术、核和质体遗传转化体系以及染色体工程等方面介绍了在植物中广泛应用的合成生物学技术。阐述了利用合成生物学开展多样化生物传感器设计、作物产量优化、营养品质强化、植物天然产物与蛋白高效合成等方面的最新研究进展。最后讨论了目前植物合成生物学所面临的问题以及今后的发展趋势。相信经过新一轮的快速发展,植物合成生物学将在未来农作物育种中发挥越来越重要的作用。

Abstract:

Synthetic biology is a new interdisciplinary field that combines engineering and biology. With an initial focus on microbial systems, it is now increasingly developed for plants. Plant synthetic biology has been applied to design crops for improved yield and nutritional value. It is also possible to transform plants into living factories for producing high-value natural products. In this review, we first summarize the definition of plant synthetic biology and introduce emerging technologies, including DNA synthesis and assembly, genome editing, genetic transformation targeting nucleus and plastid, and chromosome engineering. We then discuss recent applications in biosensor design, yield and nutrition improvement, and natural product and protein biosynthesis. We conclude with the current challenges and future perspective of this field. We envision plant synthetic biology will revolutionize crop breeding.

Key words: plant synthetic biology, gene editing, genetic transformation, metabolic engineering, biofortification, biosensors, biological parts, genetic circuits
