The bacA gene homolog, mlr7400, in Mesorhizobium loti MAFF303099 is dispensable for symbiosis with Lotus japonicus but partially capable of supporting the symbiotic function of bacA in Sinorhizobium meliloti.

Abstract excerpt

Establishment of rhizobium-legume symbiosis requires a series of mutual authentication, which might involve bacterial evasion of host defense. One such evasion-related genes is Sinorhizobium meliloti bacA that is essential for bacteroid formation. BacA is a transmembrane protein highly similar to Escherichia coli SbmA, a predicted transporter, and has homologs even in animal pathogens, such as Brucella abortus in...
