This study unveils the complete genome sequences obtained through whole-genome shotgun sequencing of four biocontrol agents originating from Solanum species samples gathered in Northern Tunisia. These genome sequences serve to enrich the current array of genomics data and provide valuable insights into the bacterial diversity intertwined with plants. Moreover, they offer a perspective into essential genes pivotal for their endophytic behaviors, interactions with host plants, and their effectiveness in biocontrol against plant pathogens. The sequencing of the bacterial strains was supported by the GetGenome initiative of The Sainsbury Laboratory, Norwich, UK, with support from the Gatsby Charitable Foundation and the Biotechnology and Biological Sciences Research Council (BBBSRC).
