Whole-genome sequencing of Fusarium oxysporum K326-S isolated from tobacco

Summary

Scientists have sequenced the complete genetic code of a fungus called Fusarium oxysporum that infects tobacco plant roots, causing them to wilt and turn brown. This fungus is a major problem for tobacco farmers because it lives in soil and is difficult to control. By mapping out all 17,272 genes in this fungus, researchers now have detailed information that will help them develop better ways to prevent and manage this disease.

Background

Root diseases are increasingly threatening plant health, particularly soil-borne pathogens. Fusarium oxysporum is a significant soil-borne fungal pathogen affecting tobacco crops. Whole-genome sequencing of such fungi provides critical insights for disease management and control strategies.

Objective

To present the whole-genome sequence of Fusarium oxysporum K326-S, a soil-borne pathogenic fungus isolated from tobacco roots exhibiting browning and wilting symptoms. This genomic data aims to provide valuable insights for future disease prevention and control research.

Results

The assembled genome of F. oxysporum K326-S is 51,143,096 bp with 1,153 scaffolds and a maximum scaffold length of 1,078,849 bp. The genome contains 17,272 coding genes, 310 tRNAs, and 63 rRNAs, with a high completeness of 98.9% based on BUSCO analysis. Functional annotation was performed against multiple databases including NR, Swiss-Prot, Pfam, eggNOG, GO, and KEGG.

Conclusion

The assembled genome of F. oxysporum K326-S expands available genomic resources for the F. oxysporum species complex and provides a solid foundation for future research on disease prevention and control. This comprehensive genomic dataset will support further investigations into pathogenicity mechanisms and management strategies.
