“…KBase is a user-friendly graphical user interface for biological informatics that is developed and maintained with significant investment from the US Department of Energy [194]. Because RSSC genomes are dispersed across several (often inaccurate) taxid pages, we developed a KBase Narrative that can help us and other scientists identify the phylogenetic identity of new RSSC genomes.…”

The Ralstonia species complex is a genetically diverse group of plant wilt pathogens. Ralstonia strains are classified by a “phylotype-sequevar” phylogenetic system. Since the development of the phylotype-sequevar system, over one hundred papers have described the genetic diversity of Ralstonia strains isolated from agriculturally important crops, ornamental plants, and plants in natural ecosystems. Our goal is to create a database that contains the reported global distribution and host range of Ralstonia sequevars. In this first release, we have catalogued information from 35 manuscripts that report one or more Ralstonia strain isolated from 50 geographic regions. The database is hosted as a GitHub repository (https://github.com/lowepowerlab/Ralstonia_Global_Diversity) that will be updated regularly.

“…Bacterial wilt, a pervasive and destructive plant disease, inflicts annual damage of approximately 1 billion US dollars. It is caused by the notorious Ralstonia solanacearum species complex. − R. solanacearum, a soil-borne Gram-negative bacterium, demonstrates strong pathogenicity across a spectrum of more than 250 plant species, including potatoes, tomatoes, tobacco, and chili. , The initial invasion occurs via secondary root emerging points, wounds, or root tips, spreading to aerial parts and resulting in severe plant wilting.…”

Ralstonia solanacearum can induce severe wilt disease in vital crops. Therefore, there is an urgent need to develop novel antifungal solutions. The natural compound 2,4-di-tert-butylphenol (2,4-DTBP) exhibits diverse physiological activities and affects soil function. However, its specific impact on the R. solanacearum remains unclear. Here, we investigated the antimicrobial potential of 2,4-DTBP. The results demonstrated that 2,4-DTBP effectively inhibited its growth and altered morphology. In addition, it substantially impeded biofilm formation, motility, and exopolysaccharide secretion. Transcriptomic analysis revealed that 2,4-DTBP inhibited energy production and membrane transport. Additionally, 2,4-DTBP hindered the growth by interfering with the membrane permeability, reactive oxygen species (ROS) production, and electrolyte leakage. Concomitantly, this led to a significant reduction in pathogenicity, as evidenced by the biomass of R. solanacearum in the invaded roots. Overall, our data strongly support the potential utility of 2,4-DTBP as a potent antibacterial agent capable of effectively preventing the onset of bacterial wilt caused by R. solanacearum.
