The Arabidopsis thaliana Database (AtDB) project at Stanford University is
pleased to announce that the latest YAC contig physical-map of chromosome
4 of Arabidopsis produced by Renate Schmidt, Caroline Dean and co-workers
is now available from our World Wide Web (WWW) server. 

The detailed arrangement of 563 YAC clones comprising four contigs
covering ~17Mbp of chromosome 4 is presented both as images of the maps
and as raw-data files. The information can be viewed, using your Web
browser (such as Netscape), either directly or as downloadable files. 
These allow you to view the complete image files at your leisure and sort
and search the original data-files using a spreadsheet, such as Excel. 

The chromosome 4 YAC-conting data relate to the paper: Renate Schmidt,
Joanne West, Gerda Cnops, Karina Love, Alma Balestrazzi, & Caroline Dean
(1996). Detailed description of four YAC contigs representing 17Mb of
chromosome 4 of Arabidopsis thaliana ecotype Columbia. The Plant Journal,
In Press. 

Also available on the Web are images of the Minimum Tiling Path for
Chromosome 4 and the Comparison of the YAC contig and RFLP map published
last year (Schmidt et al. (1995) Physical map and organization of
Arabidopsis thaliana chromosome 4. Science, 270, 480-483) and originally
prepared for WWW display by Mary Anderson at the Nottingham Arabidopsis
Stock Centre (NASC). 

In the near future, the data from Schmidt et al. for YAC Contigs on
Chromosome 5 will also be made available through the AtDB and NASC Web

To view or download the images of the YAC contigs or the raw data, either
point your Web browser to AtDB at URL: 


or, to NASC, where the same Web pages are mirrored at URL:


This latter site will probably provide quicker access for users in Europe
and elsewhere outside the US. 

The raw-data and complete-image files can also be obtained via anonymous
ftp from either: 


in the directory /arabidopsis/JIC-contigs 

or from nasc.nott.ac.uk

in the directory /pub/JIC-contigs .
