Abstract excerpt

In this study, we present a comprehensive genomic and comparative analysis of Sinorhizobium meliloti strain LPU88, highlighting the structure, function, and evolutionary dynamics of its plasmids. The complete genome sequencing revealed five replicons: a chromosome, two megaplasmids (pSymA-like pSmeLPU88c and pSymB-like pSmeLPU88d), and two accessory plasmids (pSmeLPU88a and pSmeLPU88b). Furthermore, the genome of...
