Aspergillus flavus NRRL3357 (JCVI-afl1-v2.0)

Aspergillus flavus NRRL3357 Assembly and Gene Annotation

About the Aspergillus flavus genome

Aspergillus flavus is a saprotrophic and pathogenic fungus with a cosmopolitan distribution. It is best known for its colonization of cereal grains, legumes and tree nuts. Postharvest rot typically develops during harvest, storage, and/or transit. A. flavus infections can occur while hosts are still in the field (preharvest), but often show no symptoms (dormancy) until postharvest storage and/or transport. In addition to causing preharvest and postharvest infections, many strains produce significant quantities of toxic compounds known as mycotoxins, which, when consumed, are toxic to mammals. A. flavus is also an opportunistic human and animal pathogen, causing aspergillosis in immunocompromised individuals.

The genome of Aspergillus flavus strain NRRL3357 was sequenced at 5X coverage using whole genome shotgun (WGS) sequencing. The current genome assembly (GCA_000006275.2) consists of 958 contigs assembled into 331 scaffolds.

Database construction and maintenance

The Aspergillus genome sequences and annotation is maintained and curated in an Ensembl schema by the Central Aspergillus Data Repository and made available for inclusion within Ensembl Genomes. CADRE is operated at the School of Medicine at the University of Manchester. More information about the CADRE management team is provided here.
