Abstract:
With the advancement of plant synthetic biology, plastids have emerged as an optimal platform for the heterologous production of numerous commercially valuable secondary metabolites and therapeutic proteins. In comparison on nuclear genetic engineering, plastid genetic engineering offers unique advantages in terms of efficient expression of foreign genes and biological safety. However, the constitutive expression of foreign genes in the plastid system may impede plant growth. Therefore, it is imperative to further elucidate and design regulatory elements that can achieve precise regulation of foreign genes. In this review, we summarize the progress made in developing regulatory elements for plastid genetic engineering, including operon design and optimization, multi-gene coexpression regulation strategies, and identification of new expression regulatory elements. These findings provide valuable insights for future research.
