Abstract

Diatoms are among the most diverse and ecologically significant groups of photosynthetic microalgae, contributing over 20% of global primary productivity. Their ecological significance, unique biology, and genetic tractability make them ideal targets for genetic and genomic engineering and metabolic reprogramming. Over the past few decades, numerous genetic methods have been developed and applied to these organisms to better understand the function of individual genes and how they underpin diatom metabolism. Additionally, the ability of diatoms to synthesize diverse high-value metabolites and elaborate mineral structures offers significant potential for applications in biotechnology, including the synthesis of novel pharmaceuticals, nutraceuticals, and biomaterials. This review discusses the latest developments in diatom genetic engineering and provides prospects not only to promote the use of diatoms in diverse fields of biotechnology but also to deepen our understanding of their role in natural ecosystems.

硅藻是光合微藻中种类最多、生态意义最大的一类,占全球初级生产力的 20% 以上。它们具有重要的生态意义、独特的生物学特性和遗传可操作性,因此是遗传和基因组工程以及代谢重编程的理想目标。在过去的几十年里,已经开发了许多遗传方法并将其应用于这些生物,以更好地了解单个基因的功能以及它们如何支撑硅藻的新陈代谢。此外,硅藻合成各种高价值代谢物和复杂矿物结构的能力为生物技术的应用提供了巨大潜力,包括合成新型药物、营养保健品和生物材料。这篇综述讨论了硅藻基因工程的最新发展,不仅为促进硅藻在生物技术各领域的应用提供了前景,而且加深了我们对硅藻在自然生态系统中作用的理解。

期刊介绍: Publishing the best original research papers in all key areas of modern plant biology from the world"s leading laboratories, The Plant Journal provides a dynamic forum for this ever growing international research community. Plant science research is now at the forefront of research in the biological sciences, with breakthroughs in our understanding of fundamental processes in plants matching those in other organisms. The impact of molecular genetics and the availability of model and crop species can be seen in all aspects of plant biology. For publication in The Plant Journal the research must provide a highly significant new contribution to our understanding of plants and be of general interest to the plant science community.
