Abstract

Diazotrophs are bacteria and archaea that can reduce atmospheric dinitrogen (N2) into ammonium. Plant-diazotroph interactions have been explored for over a century as a nitrogen (N) source for crops to improve agricultural productivity and sustainability. This scientific quest has generated much information about the molecular mechanisms underlying the function, assembly, and regulation of nitrogenase, ammonium assimilation, and plant-diazotroph interactions. This review presents various approaches to manipulating N fixation activity, ammonium release by diazotrophs, and plant-diazotroph interactions. We discuss the research avenues explored in this area, propose potential future routes, emphasizing engineering at the metabolic level via biorthogonal signaling, and conclude by highlighting the importance of biocontrol measures and public acceptance.

编写重氮菌和作物之间的新对话。
固氮菌是能够将大气中的二氮(N2)还原为铵的细菌和古菌。一个多世纪以来,人们一直在探索植物与重氮菌的相互作用,将其作为作物的氮源,以提高农业生产力和可持续性。这一科学探索已经产生了许多关于固氮酶的功能、组装和调节、铵同化和植物重氮相互作用的分子机制的信息。本文综述了控制固氮活性、重氮菌释放铵以及植物重氮菌相互作用的各种方法。我们讨论了该领域探索的研究途径,提出了未来的潜在路线,强调通过双正交信号在代谢水平上进行工程,并强调了生物控制措施和公众接受的重要性。
