Genome resource of Phlyctema vagabunda strain 19EL15, a pathogen of post-harvest bull’s eye rot of apple

Summary

Scientists sequenced the complete genetic blueprint of a fungus called Phlyctema vagabunda that causes serious damage to apples and pears after harvest, particularly creating brown spots called bull’s eye rot. The fungus is found across Europe and North America and costs farmers significant money in crop losses. This genetic information will help researchers better understand how the fungus works and develop better ways to prevent or manage the disease.

Background

Phlyctema vagabunda is a plant pathogenic fungus widespread in Europe and North America that causes severe post-harvest losses in apple and pear crops through bull’s eye rot disease. The fungus is also associated with olive tree leprosy. This research provides the first complete genome sequence for strain 19EL15 isolated from an infected apple fruit in South Tyrol, Italy.

Objective

To generate and annotate the complete genome sequence of Phlyctema vagabunda strain 19EL15 to provide genomic resources for understanding the pathogen’s biology and supporting future research on this economically important fungal disease.

Results

The assembled genome comprises 38.34 Mb across 13 scaffolds with an N50 of 3,904,904 bp and BUSCO completeness of 93.8%. The genome annotation predicted 11,483 protein-coding genes. High-quality genomic data and transcriptomic information are now available for future biological research.

Conclusion

The complete genome sequence of Phlyctema vagabunda strain 19EL15 provides a crucial genetic resource for understanding this important plant pathogen and supporting future research into mechanisms of pathogenicity and disease management strategies.
