wEST-SQL Database
The links below connect to a relational database containing EST, Contig, and Mapping information,
including data of the NSF DBI-9975989 project efforts.
This along with other tools has been developed to assist tracking of ESTs being used as probes for mapping to the wheat genome.
Other queries may be obtained from the GrainGenes database at the
GG2 Quick Queries Page, or at the
GG2 Advanced Query Pages.
GrainGenes Database and Companion Resources
BLAST Databases
These databases are maintained locally and serve local research activities. Custom databases
are set up to screen against Triticeae sequences, Assemblies, cDNA libraries, and other
specialty formatted databases.
The wEST resource is a USDA-ARS sponsored server of nucleic acid sequence data for
Triticeae-associated research projects located at the USDA-ARS Western Regional Research Center,
Albany, California. Other associated projects which use resources located at this site are:
wEST Tracefile Server
This location holds the sequencing records for many of the ESTs maintained in the wEST
database. Listed are the sequencing dates, plate numer (which is important
for library identification), and the quality of the sequencing run. Since
many of these samples were run on the ABI 3700 and CEQ 2000 automated
sequencers, results are shown for 96-member lots. Also available here are
the FASTA and Quality files for the run (this is untrimmed data).

Development Projects
Many of the new tools added to the databases are first tested at the development machine
located at Cornell University, Ithaca, NY. As new ideas and requests for viewing
data are suggested, they are developed and tested here.
Ongoing Projects
Wheat mapping via chromosome deletions, tool unique to wheat.

GrainGenes Probe Repository
A collection of mapped probes annotated in the GrainGenes Database Project are available for distribution.
Many of these probes are cDNAs from cereals which have been sequenced and added to the EST database. For more
