A new release of the RiceGenes database is now available as Version
3.0.3. This version is based on the ACEDB Version 3.0 software.
The next release will include a migration to ACEDB Version 4.0.
The major new category of information contained in this release is a maize map based on over 700 rice, oat, barley, and maize markers. It is an expanded version of the comparative rice-maize map published by Ahn and Tanksley in 1993. The comparative information is stored in two new classes, Chrom_Block (the maize components) and Homoeology (the rice components). We used several special genetic map display mechanisms to present this information.
If you are using the ACEDB interface, you can easily access the data by clicking on the chromosomal region of interest. A window with a description of the interval should then appear. It might help to know that the naming convention we adopted, M8-R1-n (or R1-M8-n), describes a segment in common between maize chromosome 8 and rice chromosome 1. The last digit is just a numerical designation to keep things unique. The maize map and the raw mapping data it is based on are also available as files to download from the RiceGenes gopher.
For World Wide Web users, we have incorporated hot links from the RiceGenes
database into MaizeDB for
locus and probe records.
This will give you access
to the most up-to-date
version of the maize
information. We also have
hot links into Germplasm
Resources Information
Network from various
germplasm records and into
the public sequence
databases for sequence
information.
Volumes 1-9 of the Rice Genetics Newsletter (RGN) are now available in their entirety over gopher and WWW. These summarize much historical genetic information on rice that cannot easily be found elsewhere. If your searches of the RiceGenes database dont return any hits, I would strongly recommend searching the RGNs. The gopher and WWW also include the new maize/rice comparative information.
The UNIX version of the database is available as a compressed .tar file via
anonymous ftp from the
site:
probe.nal.usda.gov, directory pub/rice, file
ricegenes3.0.3.tar.Z
Be sure to get the README.rice file as well.
