Scaffold-level genome assembly of Fusarium neocosmosporiellum strain CA18-1

Fusarium neocosmosporiellum causes alfalfa root rot, leading to significant economic losses. To explore the genetics of F. neocosmosporiellum, strain CA18-1 was isolated from infected alfalfa roots and subjected to whole-genome analysis. A scaffold-level reference genome of strain CA18-1 was assembled using both Nanopore long-read and Illumina short-read sequencing technologies. The assembled genome measured 63,424,297 base pairs (bp) in size, with a contig N50 of 6,480,858 bp and a contig N90 of 3,230,245 bp. A total of 10,486,459 bp repeat sequences and 28,006 protein-coding genes were predicted, of which 15,389 were functionally annotated. This study enhances our understanding of the genetic basis for F. neocosmosporiellum's pathogenicity, providing a foundation for future studies on disease control and fungal evolution.
