Interpretive Summary: Stem canker is an economically important disease of soybean. This disease can kill plants from the middle to the end of the growing season, resulting in severe yield loss. It is well-known that the disease is caused by a fungus (Diaporthe aspalathi), however, information about how the disease develops and how the fungus causes the disease are lacking. In the study, we used a molecular approach to sequence the causal pathogen. The genetic make-up of the fungus was investigated and analyzed. This research facilitates the identification of genes associated with fungal growth and pathogenicity, understanding of the mechanism of infection, and development of new control strategies for this pathogen.

Technical Abstract: Diaporthe aspalathi (formerly D. phaseolorum var. meridionalis) is the causal agent of the southern stem canker disease in soybean. This disease can kill plants from the middle to the end of the growing season resulting in severe yield loss. The mechanisms of disease development and pathogen invasion of soybean are not fully understood. The genome sequence of D. aspalathi has not been described. We report the de novo assembled draft genome sequence of a D. aspalathi isolate MS-SSC91, which was isolated in Mississippi, USA from the stem of a field-grown soybean plant in 2006. The resulting draft genome was estimated to be approximately 55 Mb in size with an overall G+C content of 51%. The draft genome contains 14,962 annotated genes. This research will provide information on the genetic basis of fungal infection of the soybean stem. It is valuable for studying soybean-fungal interactions and developing new control strategies for this pathogen.
