Interpretive Summary: We sequenced the genome of an aflatoxigenic Aspergillus species that is typically affiliated with silk worms. Aspergillus bombycis has been reportedly misidentified as species such as A. flavus and A. nomius, and often requires holistic comparisons to accurately delimit. Aspergillus bombycis secretes B- and G-aflatoxins like A. nomius and A. parasiticus. We sequenced the A. bombycis Type strain's genome and found it comparable in size and gene number to other sequenced Aspergillus genomes. This is an announcement that the genome of A. bombycis has been sequenced, annotated and submitted to GenBank for further research and comparison to other aflatoxigenic fungi.

Technical Abstract: The genome of the A. bombycis Type strain was sequenced using a Personal Genome Machine, followed by annotation of its predicted genes. The genome size for A. bombycis was found to be approximately 37 Mb and contained 12,266 genes. This announcement introduces a sequenced genome for an aflatoxigenic Aspergillus species that may help us to further aflatoxin research and understand the evolution of aflatoxigenic fungi.
