摘要:

近年来,农业生产面临磷源匮乏和环境污染的双重挑战,亚磷酸脱氢酶(phosphite dehydrogenase, PTDH)的发现和应用为解决这一问题提供了新的思路。在微生物中,PTDH使得非无菌环境下的高效发酵成为可能,降低了成本并提高了生产效率。在植物中,PTDH不仅解决了磷源问题,还为除草剂的开发提供了新的途径。此外,亚磷酸盐可作为一种潜在的除草剂和磷源使用,相比传统除草剂更环保、成本更低、稳定性更好。尽管亚磷酸脱氢酶的应用研究取得了显著进展,但目前仍处于功能解析和概念验证阶段,对亚磷酸脱氢酶的催化机理、蛋白结构和酶活改良等方面的研究还需进一步深入。综述了PTDH在微生物、模式植物(如拟南芥和烟草)、经济作物(如棉花和油菜)以及粮食作物(如水稻和玉米)中的应用进展。随着蛋白质定向进化技术、基因转化和基因编辑技术的发展,未来将进一步优化亚磷酸脱氢酶的应用效果,为作物的高效利用亚磷酸盐和环境保护提供更多可能。

Abstract:

In recent years, agricultural production is facing the dual challenges of phosphorus deficiency and environmental pollution. The discovery and application of phosphite dehydrogenase (PTDH) provides a new idea to solve this problem. In microorganisms, PTDH makes efficient fermentation in non-sterile environments possible, reducing costs and increasing production efficiency. In plants, PTDH not only solves the problem of phosphorus source, but also provides a new way for the development of herbicides. In addition, the use of phosphite as a potential herbicide and phosphorus source is more environmentally friendly, low cost and stable than traditional herbicides. Although significant progress has been made in the application of phosphite dehydrogenase, the current research is still in the stage of functional analysis and conceptual verification. The research on the catalytic mechanism, protein structure and enzyme activity improvement of phosphite dehydrogenase needs to be further studied. This study reviewed the application of PTDH in microorganisms, model plants (such as Arabidopsis and tobacco), cash crops (such as cotton and rapeseed) and food crops (such as rice and corn). In the future, with the development of protein directed evolution technology, gene transformation and gene editing technology, the application effect of phosphite dehydrogenase will be further optimized, which will provide more possibilities for efficient utilization of phosphite and environmental protection of crops.

Key words: phosphite dehydrogenase, phosphorus source, genetic engineering, microorganism, plant
