Streptomyces spp. constitute a major clade of the phylum Actinobacteria. These Gram-positive, filamentous prokaryotes are ubiquitous in soils and marine sediments, and are commonly found in the rhizosphere or inside plant roots. Plant-interacting Streptomyces have received limited attention, in contrast to Streptomyces spp. extensively investigated for decades in medicine given their rich potential for secondary metabolite biosynthesis. Recent genomic, metabolomic, and biotechnological advances have produced key insights into Streptomyces spp., paving the way to the use of their metabolites in agriculture. In this Opinion article we propose how Streptomyces spp. could dominate future aspects of crop nutrition and protection. Risks and benefits of the use of these microorganisms in agriculture are also discussed.
链霉菌属是放线菌门的一个主要分支。这些革兰氏阳性、丝状的原核生物在土壤和海洋沉积物中无处不在，通常存在于根际或植物根部内部。与几十年来在医学领域得到广泛研究的链霉菌属相比，与植物相互作用的链霉菌属受到的关注有限，因为它们在次生代谢物生物合成方面具有丰富的潜力。最近的基因组学、代谢组学和生物技术的进步为链霉菌属提供了关键的见解，为其代谢产物在农业中的应用铺平了道路。在这篇观点文章中，我们提出了链霉菌属如何主导未来作物营养和保护的各个方面。还讨论了这些微生物在农业中的使用的风险和益处。
