The beta-rhizobial strain Paraburkholderia phymatum STM815 is noteworthy for its wide host range in nodulating legumes, primarily mimosoids (over 50 different species) but also some papilionoids. It cannot, however, nodulate soybean (Glycine max [L.] Merr.

- Bacteria are versatile organisms that thrive in various environments and engage in different relationships with other organisms, ranging from beneficial to harmful.
- Understanding the genetic factors that allow bacteria to colonize host organisms is essential for finding new treatments for diseases and developing agricultural enhancements.
- Recent advancements in genetic research have improved our ability to identify key pathways for host colonization, but more research is needed to clarify how these genes function across different bacterial species.
Paraburkholderia sabiae LMG24235 is a nitrogen-fixing betaproteobacterium originally isolated from a root nodule of Mimosa caesalpiniifolia in Brazil. We show here that this strain effectively kills strains from several bacterial families (, , ) which include important plant pathogens in a contact-dependent manner. assembly of the first complete genome of using long sequencing reads and subsequent annotation revealed two gene clusters predicted to encode type VI secretion systems (T6SS), which we named T6SS-1 and T6SS-3 according to previous classification methods (G.

- The pathogen studied is an opportunistic bacteria that poses severe risks for patients with cystic fibrosis and chronic granulomatous disease.
- Researchers discovered that a specific isolate of this bacteria, H111, can survive without oxygen, which is unusual for an obligate aerobe.
- Through transposon sequencing, 71 factors essential for survival in anoxic environments were identified, with specific genes linked to virulence and movement, underscoring their importance in the bacteria's lifecycle and pathogenicity.
is a soil saprophyte that is closely related to the pathogen , the etiological agent of melioidosis in humans. The environmental niches and infection sites occupied by these bacteria are thought to contain only limited concentrations of oxygen, where they can generate energy via denitrification. However, knowledge of the underlying molecular basis of the denitrification pathway in these bacteria is scarce.
