bacteria have been studied for more than 80 years thanks to their ability to produce an incredible array of antibiotics and other specialized metabolites and their unusual fungal-like development. Their antibiotic production capabilities have ensured continual interest from both academic and industrial sectors, while their developmental life cycle has provided investigators with unique opportunities to address fundamental questions relating to bacterial multicellular growth. Much of our understanding of the biology and metabolism of these fascinating bacteria, and many of the tools we use to manipulate these organisms, have stemmed from investigations using the model species Streptomyces coelicolor and Streptomyces venezuelae. Here, we explore the pioneering work in S. coelicolor that established foundational genetic principles relating to specialized metabolism and development, alongside the genomic and cell biology developments that led to the emergence of as a new model system. We highlight key discoveries that have stemmed from studies of these two systems and discuss opportunities for future investigations that leverage the power and understanding provided by S. coelicolor and .
由于能够产生令人难以置信的抗生素和其他特殊代谢物阵列以及其不寻常的真菌样发育,细菌已经被研究了 80 多年。它们的抗生素生产能力确保了学术界和工业界的持续关注,而它们的发育生命周期为研究人员提供了独特的机会,可以解决与细菌多细胞生长相关的基本问题。我们对这些迷人细菌的生物学和新陈代谢的大部分理解,以及我们用来操纵这些生物体的许多工具,都源于对模型物种链霉菌和委内瑞拉链霉菌的研究。在这里,我们探讨了在链霉菌中进行的开创性工作,该工作确立了与特殊代谢和发育相关的基础遗传原理,以及导致作为一个新的模型系统出现的基因组和细胞生物学发展。我们强调了源于这两个系统研究的关键发现,并讨论了利用链霉菌和提供的力量和理解进行未来研究的机会。
