摘要

Background

Beneficial plant-associated microorganisms are key drivers of sustainable agriculture. However, their discovery and practical application remain insufficiently explored. Here, we present the first comprehensive comparative genomic analysis of a newly identified Sinomonas strain together with all publicly available genomes to assess its agronomic potential.

Results

Our results demonstrate that Sinomonas has an open pangenome and harbors multiple pathways for IAA biosynthesis, including a rare pathway found in only a limited number of bacterial taxa. The genus also contains genes involved in the synthesis of cytokinin analogues. In addition, genomic annotation identified ten genes putatively associated with phosphorus solubilization. A total of sixteen distinct biosynthetic gene clusters were identified, covering pathways for the biosynthesis of stenothricin, dactylocycline, aborycin, reveromycin, michiganin A, ikarugamycin, and peucechelin, all of which are compounds with reported antibacterial activity. In addition, Sinomonas carries multiple genes potentially involved in improving plant stress tolerance, including genes related to the biosynthesis of spermidine, 2,3-butanediol, acetoin, betaine, proline, and trehalose.

Conclusion

Overall, these findings highlight the functional diversity of the Sinomonas genome and provide preliminary insights into its potential agricultural applications.
