[January 2019] The Penicillium atramentosum RS17 genome was assembled by Rachel Dutton's group at the University of California, San Diego from Oxford nanopore minion reads, then polished with Illumina short reads using pilon.

The DOE Joint Genome Institute identified several scaffolds containing > 80% bacterial gene models, which were removed from the assembly. In addition, some chimeric scaffolds were identified based on GC-content (this fungal genome averages around 50% GC and the bacterial sequence around 65%) and bacterial gene models, which were spliced and rejoined to remove contaminating sequences. This annotation version 1.0 represents the cleaned assembly.
