Draft genome sequence resource for blumeriella jaapii, the cherry leaf spot pathogen

Abstract

Blumeriella jaapii is the causal agent of cherry leaf spot (CLS), the most important disease of tart cherry in the Midwestern United States. Infection of leaves by B. jaapii leads to premature defoliation, which places trees at heightened risk of winter injury and death. Current management of CLS relies primarily on the application of three important fungicide classes, quinone outside inhibitors, sterol demethylation inhibitors, and succinate dehydrogenase inhibitors. Here, we present the first high-quality genome of B. jaapii through a hybrid assembly of PacBio long reads and Illumina short reads. The assembled draft genome of B. jaapii is 47.4 Mb and consists of 95 contigs with a N50 value of 1.5 Mb. The genomic information of B. jaapii, representing the most complete sequenced genome of the family Dermateaceae (Ascomycota) to date, provides a valuable resource for identifying fungicide resistance mechanisms of this pathogen and expands our knowledge of the phytopathogenic fungi in this family.
