AspGD is an organized collection of genetic and molecular biological
information about the filamentous fungi of the genus
Aspergillus. Among its many species, the genus contains an excellent
model organism (A. nidulans, or its teleomorph Emericella nidulans),
an important pathogen of the immunocompromised (A. fumigatus), an
agriculturally important toxin producer (A. flavus), and two species
used in industrial processes (A. niger and A. oryzae). AspGD contains
information about genes and proteins of multiple Aspergillus species;
descriptions and classifications of their biological roles, molecular
functions, and subcellular localizations; gene, protein, and
chromosome sequence information; tools for analysis and comparison of
sequences; and links to literature information; as well as a
multispecies comparative genomics browser tool (Sybil) for exploration
of orthology and synteny across multiple sequenced Aspergillus

New and Noteworthy
Aspergillus annotation updates
The reference gene sets in AspGD have been updated, based on PASA analysis conducted by AspGD in 2015. The following changes were made:
Please, visit the Chromosome History page to review the changes.
(Posted September 15, 2015)
A. nidulans - 5 new features were added, and 4 former pseudogenes were reannotated as uncharachterized ORFs;

AspGD Curation News
AspGD and FungiDB integration
AspGD data are being integrated into FungiDB. Please click here for additional details.
Discussion of how to maximize the value of FungiDB for the Aspergillus research community will be a major topic at the upcoming
AsperFest12 meeting at Asilomar (March 16-17, 2015). |
An open letter to the Aspergillus research community on genome database resources:
As many of you may already be aware, the NIH R01 research grant that has supported development of the AspGD database will not be
renewed … not because the NIH doesn't appreciate the value and importance of this resource to the Aspergillus research community,
but because the current funding climate makes it difficult to support curation-intensive databases serving individual pathogens
and relatively small research communities. However, NIH has provided one year of funding to ensure that information from AspGD
is integrated into FungiDB, a component of the EuPathDB Bioinformatics Resource Center. We do not anticipate that AspGD will
disappear: you should still be able to access the existing web site, at least for the foreseeable future, but curatorial
engagement will have to be significantly reduced over the coming months.
The EuPathDB family of databases supports a wide range of microbial eukaryotes, including protozoan parasites and many fungal and
oomycete species, including non-pathogens. This resource has been specifically designed to provide sustainable, cost-effective
automated analysis of multiple genomes, integrating curated information where available, along with comments and supporting
evidence from the user community (PubMedIDs, phenotypic information, images, datasets, etc). In addition to gene records,
browser views, and data downloads, FungiDB also provides a variety of sophisticated tools for integrating and mining diverse
Omics datasets, which we expect that Aspergillus researchers and other fungal biologists will find quite useful. See sidebar on
the FungiDB web site for access to tutorials, videos, and exercises; more fungi-specific materials should become available over
the coming months.
AspGD and FungiDB/EuPathDB will be working together to maximize value to the Aspergillus community, given the limited resources
available. The upcoming AsperFest12 and 28th Fungal Genetics meetings in Asilomar (March 16-22, 2015) will be attended by staff
from both groups, with presentations and a ‘help-desk’ to introduce the Aspergillus community to FungiDB. We look forward to
productive discussions on how to ensure that Aspergillus researchers retain access to information from AspGD, learn to use
FungiDB effectively and have a voice in its further development, and craft a strategy for meeting future informatics needs.

Sequence trace files available
We have added archival Aspergillus sequence data from the NCBI TraceDB site, and these data are now available
from our AspGD download site.

New "Big 4" ortholog alignment
We have added a new, streamlined, four-species protein alignment to the ortholog cluster pages in our Sybil Comparative Genomics
Viewer. This "Big 4" alignment displays a Clustal protein alignment of the orthologs from A. nidulans FGSC A4, A.
oryzae RIB40, A. fumigatus Af293 and A. niger CBS513.88 (see example). As we continue to add new species into our Sybil
Comparative Genomics Viewer, the number of proteins represented in each multispecies ortholog cluster has grown significantly. We
continue to provide an alignment of all of the orthologs from the full set of species, and now include the "Big 4" alignment in
addition. We hope this feature is helpful, and we welcome your feedback any time.

A. niger annotation updates
The A. niger reference gene set has been updated, based on PASA analysis. 4,123 features were affected: 543 CDSs were
extended and 195 shortened; 30 features were merged into 15 features; 2,907 5-prime UTRs and 2,601 3-prime UTRs were added or
modified; New exons were added to the ends of 270 features, and the internal intron/exon structure was modified for 491 features.
The GBrowse Genome Browser displays the old annotation as a "Historic Track" to facilitate visual comparison, for example, of new UTRs or gene model structure updates, for example, a gene merge. The current and historic reference annotation can be viewed alongside RNA-Seq transcript
data in AspGD JBrowse (zoom in to see spliced reads across intronic regions, including the intron within what was previously
annotated as an intergenic region).

RNA-Seq data used to improve reference annotation for A. fumigatus
We have made significant updates to the structural annotation of the Aspergillus fumigatus Af293 reference genome based on
PASA analysis using RNA-Seq data (from Müller et al. ) to provide experimental support for gene
model modifications. The coordinates of 5,174 features were updated: 1,044 CDSs were extended and 641 shortened; 28 features
were merged into 14 features; 4,524 5-prime UTRs and 3,545 3-prime UTRs were added or modified; New exons were added to the ends
of 1,255 features, and the internal intron/exon structure was modified for 1,133 features.
In addition, we have updated the structural annotation of the Aspergillus fumigatus A1163 (CEA10) strain, which is not the
reference strain, but for which we provide sequence files, protein domain files, and mulispecies BLAST capabilities. The PASA analysis of A. fumigatus A1163 utilized RNA-Seq data
provided by JCVI (SRA project SRP003796).
