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

Summary

Scientists sequenced the complete genome of a fungus that causes disease in tobacco plants. The fungus, Fusarium oxysporum, was isolated from diseased tobacco roots in China. The resulting genetic blueprint contains over 17,000 genes and will help researchers develop better ways to prevent and control this destructive plant disease.

Background

Root diseases caused by soil-borne pathogens increasingly threaten plant health. Fusarium oxysporum is a significant pathogenic fungus that affects various crops including tobacco. Whole-genome sequencing provides critical insights for understanding and controlling fungal diseases.

Objective

To present the whole-genome sequence of Fusarium oxysporum K326-S, a pathogenic fungus isolated from diseased tobacco roots. This genomic resource aims to support future research on disease prevention and control strategies.

Results

The assembled genome is 51,143,096 bp with 1,153 scaffolds and a maximum scaffold length of 1,078,849 bp. Gene prediction identified 17,272 coding genes along with 310 tRNAs and 63 rRNAs. BUSCO analysis confirmed high genome completeness at 98.9%.

Conclusion

The genomic assembly of F. oxysporum K326-S expands available resources for the F. oxysporum species complex. This high-quality genome sequence provides a foundation for future research on fungal pathogenesis and disease control mechanisms.
