Rhizobium laguerreae is a nitrogen-fixing bacterium with prospects in legume bio-inoculant design. Its ability to form symbiotic relationships with legume plants makes it an important target for agricultural biotechnology research. Pan-genome analysis can provide valuable insights into the genetic diversity and functional potential of R. laguerreae. This study aims to analyze 98 genome sequences of R. laguerreae, including six unique AMPS strains, in order to understand its intricate genetic architecture and metabolic capabilities. By analyzing the core and accessory genome components, we aim to identify the genetic determinants responsible for the symbiotic efficiency and adaptability of R. laguerreae. Thus, the detection of two key enzymes in effective strains—allophanate hydrolase and UDP-N-acetylglucosamine 4,6-dehydratase— indicates their crucial role in symbiotic performance.
