Introducing JBrowse for CGD
CGD has implemented JBrowse, the fast, intuitive, and customizable
genome browser developed by the Generic Model Organism Database project
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:
We will be adding additional high-throughput datasets in the coming months.
- 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
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.

CGD Curation News
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
to within the coding sequence of the gene
This results in sequence and gene model boundary changes for most chromosome 3 features.

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.

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.

Updates to C. glabrata genome annotation
Multiple C. glabrata gene models were updated based on gene expression analysis conducted by Linde et al. (2015).
4,994 features were affected: 107 new features
were added, including 49 protein-coding genes and 58 non-coding RNAs; 4 ORFs were deleted; the sequences for 132 features were extended and 10
shortened; 15 features were split to create 35 new features; 2 features were merged to create 1 new feature; 4,819 5-prime UTRs and 4,828 3-prime UTRs
were added; The intron/exon structure was modified for 60 features; splice variants were identified for 16 features. For a list of updates, see

Assembly 22 of the C. albicans genome sequence
We are pleased to announce that Assembly 22 of the C. albicans SC5314 genome sequence has now become available at CGD, fully integrated into the
CGD environment. Assembly 22 (A22) is described in Muzzey D., et
al. (2013) Assembly of a phased, diploid Candida albicans genome facilitates allele-specific measurements and provides a simple model for repeat
and indel structure. Genome Biol. 2013 Sep 11;14(9):R97.
Taking advantage of next-generation sequencing and achieving nearly 700-fold
coverage, this phased, diploid assembly permits more sensitive, allele-specific analysis of the genome structure and funcion. A22 supersedes the
previous Assembly 21 as the default genome sequence for C. albicans SC5314. All the previous assemblies remain available at CGD's download

Introducing GeneXplorer for CGD
We have implemented GeneXplorer, a web tool for browsing and analysis of expression datasets and, so far, we have added microarray datasets from over
30 publications already archived at CGD. Each of those publication is linked via an icon to a GeneXplorer-generated web page that shows a colorimetric image of the clustered expression profiles. These images are
zoomable and clickable (click on any profile to see the expression patterns of the most similarly or dissimilarly expressed genes). The publications
are also linked (via ) to a downloadable data file in the pcl format. We are focusing our efforts on the microarray datasets
and more publications are added to GeneXplorer every week.
