Complete genome sequence of Paenibacillus polymyxa 19197, an endophytic bacterium isolated from the morel mushroom Morchella importuna

Key Points

To sequence the complete genome of Paenibacillus polymyxa 19197 and explore its functional capabilities.
Isolation of Paenibacillus polymyxa from Morchella importuna
Genome sequencing to obtain the complete genome sequence
Analysis of encoded enzymes and operons
The genome is a 6.93 Mb circular chromosome
Encodes 220 glycoside hydrolases, indicating carbohydrate degradation capabilities
Contains a complete nitrogenase operon, suggesting nitrogen fixation potential

Abstract

ABSTRACT We report the complete genome sequence of Paenibacillus polymyxa 19197, an endophyte isolated from Morchella importuna . 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
