Draft genome sequence data of Fusarium verticillioides strain REC01, a phytopathogen isolated from a Peruvian maize

Summary

Researchers sequenced the genome of a fungus that causes rot disease in corn plants, specifically from samples found in Peru. The fungus produces toxins that harm both human and animal health and reduces crop yields. By analyzing the fungus’s genetic code and comparing it with other strains, scientists can better understand how it causes disease and develop better strategies to protect corn crops.

Background

Fusarium verticillioides is a major phytopathogenic threat to maize crops worldwide, producing mycotoxins that impact human and animal health and cause significant economic losses. The pathogen has multiple infection routes including systemic infection in seedlings and stem infections through mechanical damage. Understanding local strains and their genetic variability is crucial for developing targeted management strategies.

Objective

To present genomic sequence data of F. verticillioides strain REC01 isolated from maize stems showing vascular rot symptoms in Peru. The study aimed to perform comprehensive microbiological identification, pathogenicity testing, and genomic analysis with comparative studies against other Fusarium genomes.

Results

The assembly yielded 456 contigs totaling 42.8 Mb with GC content of 48.26%. BUSCO analysis showed 97.55% complete sequences. Pathogenicity testing demonstrated reduced seed germination from 100% (control) to 57.10% and 33.30% with increasing inoculum concentrations. SSR analysis identified 3113 microsatellite loci with a frequency of 72.62 SSR/Mb.

Conclusion

The genomic data of F. verticillioides strain REC01 provides valuable information for comparative genomic studies and understanding pathogenicity mechanisms. This information enables development of genetic engineering strategies and contributes to understanding the evolutionary relationships within the Fusarium genus and improving regional disease management.
