Interpretive Summary: Phomopsis seed decay of soybean is a major cause of poor quality of soybean seeds. The disease is caused primarily by a fungus, but 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 invested 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: Phomopsis longicolla T.W. Hobbs is the primary cause of Phomopsis seed decay in soybean. We report the de novo assembled draft genome sequence of P. longicolla type strain TWH P74. The resulting draft genome was estimated to be approximately 64 Mb in size with an overall G+C content of 48.1%. The draft genome contains 16,606 annotated genes. The draft genome of the type strain TWH P74 of P. longicolla represents one of the important seed-borne fungal pathogens in the Diaporthe-Phomopsis complex. The P. longicolla genome sequence provides molecular resources for developing genetic markers to study the genetic variability of this pathogen, and valuable for studying soybean-fungal interactions. It 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.
