Draft genome sequence of Marssonina coronaria, causal agent of apple blotch, and comparisons with the Marssonina brunnea and Marssonina rosae genomes.

ABSTRACT: Marssonina coronaria Ellis & Davis is a filamentous fungus in the class Leotiomycetes that causes apple blotch, an economically important disease of apples worldwide. Here, we sequenced the whole genome of M. coronaria strain NL1. The genome contained 50.3 Mb with 589 scaffolds and 9,622 protein-coding genes. A phylogenetic analysis using multiple loci and a whole-genome alignment revealed that M. coronaria is closely related to Marssonina rosae and Marssonina brunnea. A comparison of the three genomes revealed 90 species-specific carbohydrate-active enzymes, 19 of which showed atypical distributions, and 12 species-specific secondary metabolite biosynthetic gene clusters, two of which have the potential to synthesize products analogous to PR toxin and swainsonine, respectively.
