About CGD

This is the home of the Candida Genome Database, a resource for genomic sequence data and gene and protein information for Candida albicans and related species. CGD is based on the Saccharomyces Genome Database and is funded by the National Institute of Dental & Craniofacial Research at the US National Institutes of Health.

CGD Grant Renewal - letters of support

As you know, the CGD grant is up for renewal this year and we are going to submit an application to the NIH this summer. We have previously asked members of the community to complete a User Survey to help us formulate future directions for CGD and we greatly appreciate the massive response we have received, with all the invaluable suggestions. We are now asking our users for letters of support to accompany the application. It is very important to demonstrate unequivocally how crucial the continued existence of CGD is to Candida research and to the community. We will greatly appreciate if you can email your letter of support to by June 15 and if you also encourage your colleagues and students to do the same. We are counting on your support.

CGD Curation News


Issue with contacting CGD

It was brought to our attention that our CGD Suggestions and Questions form, the one with the reCAPTCHA box, was not working properly. There may have been messages that were inadvertently lost. If you recently tried to contact CGD and never received a response, it is most likely because we have not seen your message. We sincerely apologize for this. The problem is now fixed and we also implemented measures to alert us to this kind of issues in the future.

Candida glabrata MLST database accepting submissions

Candida glabrata Multi Locus Sequence Typing (MLST) database at PubMLST.org is accepting submissions again. As of August 2018, the C. glabrata MLST database hosted at pubmlst.org has re-opened its submission pipeline. They welcome submissions of new alleles and sequence types as well as isolate data from ongoing or published studies. Also the submission of genome data is possible to place them into the phylogenetic context of the current MLST scheme.

Please visit pubmlst.org/cglabrata for more information.

C. lusitaniae strain CBS 6936 sequence and BLAST datasets now available at CGD

The sequence and annotation of C. lusitaniae strain CBS 6936, described in Durrens et al. (2017), has been made available at CGD. We provide downloads for sequences, chromosomal features, gff files and protein domain predictions. In addition, C. lusitaniae CBS 6936 is included among the datasets searchable by our multi-species BLAST tool. The sequence and annotation were obtained by CGD from NCBI.

JBrowse Conservation Tracks

CGD has added tracks in JBrowse showing the evolutionary conservation of genomic features for C. albicans SC5314, C. glabrata CBS138, C. dubliniensis CD36, and C. parapsilosis CDC317. Conservation is shown in four optional quantitative tracks, representing increasing levels of evolutionary diversity. In general, the top level (derived from an alignment of 3 closely related species) will show the highest levels of conservation, and include intergenic regions, while the lowest level (derived from an alignment of 12 distantly-related budding yeasts) will show the least conservation, and include only the most highly-conserved genes and features. Conservation scores were produced with the phyloP program (Siepel et al, 2005), based on whole-genome alignments produced by the program TBA (Blanchette et al, 2004).

Conservation scores and their underlying alignments and phylogenetic models are available for download in the CGD downloads directory. Please see our JBrowse Help Page for more information about JBrowse at CGD.

Introducing JBrowse for CGD

CGD has implemented JBrowse, the fast, intuitive, and customizable genome browser developed by the Generic Model Organism Database project (GMOD). JBrowse allows users to quickly view large-scale sequence data in a genomic context, at multiple zoom-levels of resolution, from base pairs in individual sequence reads to read-density summaries across large genomic regions. Initially, we have loaded the following datasets:
  • Gene expression in C. albicans in a variety of experimental conditions from Bruno et al, 2010
  • Gene expression in C. glabrata in a variety of experimental conditions from Linde, Duggan et al, 2015
  • High-throughput genomic sequence of C. albicans SC5314 from Muzzey et al, 2013, that was the basis of Assembly 22
We will be adding additional high-throughput datasets in the coming months.

JBrowse can be launched from any CGD feature's Locus Summary Page by clicking on the JBrowse logo about halfway down the page:

The JBrowse window will be centered upon that feature.

Alternately, mouse-over "JBrowse" on the top menu bar of any CGD page, then select and click your organism of interest in the drop-down menu. The browser window will be centered on an arbitrary location of the genome.

Please see our JBrowse Help Page for more details.

Correction of chromosome 3 haplotype information for C. albicans SC5314 Assembly 22

We have corrected the haplotype assignments on chromosome 3 of C. albicans SC5314, based on comparisons of haplotype data (Legrand et al, 2008; Berman and Forche, 2016) with sequence data (Muzzey et al, 2013) for both the wild-type diploid strain and the strain RBY10-10, which is homozygous for chromosome 3A. This analysis supported the exchange of approximately 845 kbp between chromosome 3A and chromosome 3B of Assembly 22 at CGD, including the entire left arm of the chromosome, and a portion of the right arm extending from CEN3 to within the coding sequence of the gene C3_04040W (orf19.2804). This results in sequence and gene model boundary changes for most chromosome 3 features. (Posted June 22, 2016)

EnsemblFungi gene annotations for Candida strains not curated by CGD

We now provide links on CGD Homology Pages and CGD Multi-Genome BLAST results pages to gene annotations from EnsemblFungi for the seven Candida-related strains for which we provide sequence and gene model downloads, but do not actively curate: C. albicans WO-1, C. guilliermondii ATCC 6260, C. lusitaniae ATCC 42720, C. orthopsilosis Co 90-125, C. tropicalis MYA-3404, D. hansenii CBS767 and L. elongisporus NRLL YB-4239. These replace the links to annotations formerly provided by the Broad Institute Fungal Genome Initiative, which are no longer supported. (Posted June 6, 2016)

Major update of the C. albicans genome sequence at CGD

We have released a major sequence update for C. albicans SC5314 (Assembly 22, version s06-m01-r01). Based on reanalysis by CGD of all available sequence data, the update affects more than 300 features, correcting many ORF translation errors and resolving many sequence ambiguities. The specific sequence changes can be viewed on our Chromosome History pages. (Posted February 2, 2016)
