Interpretive Summary: Dactylonectria macrodidyma is a fungus that causes diseases of many important crop plants, including grapevine, avocado, and olive. In order to understand the genetic mechanisms contributing to plant pathogen virulence, plant degradation, and toxin production, the complete genome of D. macrodidyma was sequenced and genes predicted. Knowledge of the genetic diversity of this fungus will help scientists to identify the DNA and genes involved in the development of diseases of crop plants, thereby leading to new methods of disease control.

Technical Abstract: Dactylonectria macrodidyma is part of the Nectriaceae, a family containing important plant pathogens. This species possesses the ability to induce disease on grapevine, avocado and olive. Here, we report the first draft genome of D. macrodidyma isolate JAC15-08. The assembled genome was 58 Mbp and contained an estimated 16,454 genes.
