Potential core and dispensable chromosomes in the genomes of Dothideomycetes.

Mycosphaerella graminicola has been shown previously to contain dispensable (i.e., not necessary for survival) chromosomes [24]. These chromosomes are smaller, less gene-dense and more repeat-rich than the core chromosomes. Proteins encoded by genes on these chromosomes less frequently contain a PFAM domain. Scaffolds with similar characteristics are also present in five other Dothideomycetes. Additional statistics for these scaffolds are given in Table S12.
