What's new at GDR?
1. GDR Renewal Proposal Submitted to NSF Plant Genome Program
In November 2005, a multi-institution proposal was submitted to the National
Science Foundation Plant Genome Program to renew funding support
for GDR through August 2009. The proposal if funded will significantly
enhance the functionality and usefulness of GDR for the rosaceae
community. If you would like more information on this proposal please contact Dorrie
Main.
2. New EST libraries are available.
The diploid strawberry species, Fragaria vesca, a putative genome donor to the octoploid, cultivated species (Fragaria x ananassa) is being been developed as a model system for genetic and genomic research in strawberry. Tom Davis at the University of New Hampshire, USA, has provided 2717 ESTs
from the unopened flower buds of diploid strawberries. A full analysis
results of his library can be viewed/downloaded from the
project page and the ESTs can be queried at the
EST search site.
Peach (Prunus persica) represents a model species for prunus and a reference
species for Rosaceae. To develop an extensive Prunus EST database for
identification and cloning of genes important to fruit and tree development, Bert Abbott at Clemson University, USA, generated 8832 high-quality expressed sequence tags (ESTs) from a peach cDNA
library of shoot tissue. After assembly and annotation, a putative peach unigene
set consisting of 5381 ESTs was defined. A full analysis
results of his library can be viewed/downloaded from the project page and the ESTs can be queried at the EST search site.
3. Rosaceae Unigene v2 with enhanced
annotation available.
A second version of the Rosaceae family unigene is now available. A
new assembly process is being utilized; the ESTs are assembled using
CAP3 within each genera (Fragaria, Malus, Prunus, Pyrus, and Rosa),
and these assemblies are compiled and re-assembled together to produce
the family-wide unigene. The new Rosaceae Unigene contains 72114
unigenes. Putative function has been assigned using the arabidopsis protein database and will be further expanded using the swissprot and NCBI nr protein
databases. The unigenes have been analyzed for microsatellites and the results including suggested primers can be downloaded. Please see each project page (Fragaria, Malus, Prunus, Rosa and Rosaceae) to view/download all the GDR unigene data.
4. Prunus bin map is available
in CMap and marker search engine.
A Prunus
bin map (Howad
et al., 2005), is now available in GDR. CMap displays
the prunus bin map with bin names and the first/ last markers of
each bin, and the bin-mapped markers are displayed in each bin page.
For
example,
all
the bin mapped
markers of the first bin in G1 are shown in bin
1:14 page. All the markers in the prunus bin map can be queried
through the GDR
marker search page.
5. Enhanced SSR server now available with primer generating option.
The online SSR
server at GDR has been enhanced to include an option to have
primers generated for the sequences that users wish to data mine
for microsatellites.
6. More databases
are available for BLAST/FASTA sequence
similarity search.
The databases available for blast/fasta sequence similarity search
includes the following: peach ESTs, unigenes and ESTs with SSR's,
BAC anchored peach ESTs, mapped peach ESTs, almond
ESTs
and unigenes (Abbott, Clemson U); peach ESTs and unigenes,
peach ESTs with SSR's (Vendramin,
CRA
ISF); octoploid strawberry ESTs, unigenes, and ESTs with SSRs (Folta,
U of Florida); diploid strawberry ESTs and unigenes (Davis, U of
New Hampshire); ESTs of Fragaria, Malus, Prunus, Pyrus, Rosa, and
entire Rosaceae family from NCBI dbEST; NCBI Rosaceae genomic sequences;
NCBI Rosaceae protein sequences; Arabidopsis protein sequences from
TAIR. A detailed description
of the databases is available in
each search engine. The blast/fasta sequence servers return the output
of the searches in both a parsed excel file and as a raw output file
with visual alignments.
7. Data available for the three
peach BACs that are completely sequenced.
Anchored ESTs/markers and the sequences for the
three BACs (082I18,
028F08 and
pPn31C7) can be accessed from BAC
search site. An online annotation pipeline is currently under development
by the GDR team.
8. New Rosaceae Executive Committee web page created to provide a communication portal for information and reports generated by the committee.
9. The GDR publications database now contains 242 papers relevant to Rosaceae genetics/genomics. New publications since our last newsletter are listed below:
