Complete genome sequence of <i>Paenibacillus polymyxa</i> 19197, an endophytic bacterium isolated from the morel mushroom <i>Morchella importuna</i>
We report the complete genome sequence of <i>Paenibacillus polymyxa</i> 19197, an endophyte isolated from <i>Morchella importuna</i>. The 6.93 Mb circular chromosome encodes a diverse array of carbohydrate-active enzymes (CAZymes), including 220 glycoside hydrolases, and a complete nitrogenase operon, suggesting roles in polysaccharide degradation and nitrogen fixation within the morel ecosystem.
