Interpretive Summary: Coniothyrium glycines is a fungal pathogen that causes a severe disease known as red leaf blotch of soybean. The distribution of the pathogen is currently limited to a few African countries. C. glycines is listed by USDA as a plant pathogen Select Agent due to the risk for US agriculture, economics, and trade. However, little is known about the biology and genetics of the fungus, and currently, no molecular detection methods are available. The lack of information on C. glycines makes it important to conduct studies to understand its biology. We report here assembled genomic sequences to provide a valuable resource for ongoing studies that include marker development, diagnostics, and population diversity. The genomes will provide plant pathologists and regulatory agencies with information for development of diagnostic assays needed to detect the pathogen in commodities and at ports of entry. Soybean researchers will use the information to identify pathogen population structures and identify potential virulence factors that breeders will find useful in testing and deployment of novel resistance genes.

Technical Abstract: Coniothyrium glycines (R.B. Stewart) Verkley & Gruyter is a fungal pathogen that causes a severe disease known as red leaf blotch of soybean. The distribution of the pathogen is currently limited to a few African countries. C. glycines is listed by USDA under 7CFR part 331 as a plant pathogen Select Agent due to the extreme risk for US agriculture, economics, and trade. However, little is known about the biology and genetics of the fungus, and currently, no molecular detection methods are available. The lack of information on C. glycines makes it important to conduct studies to understand its biology. Combining read data from the MinION Mk1C system and the Illumina NextSeq platform, we report genomic sequences produced under two de novo hybrid assembly approaches to provide a valuable resource for ongoing studies that include marker development, diagnostics, and population diversity.
