- Genome-wide fingerprinting of the TAMU and IGF BAC libraries has allowed Marco Marra and colleagues at Washington University to build BAC contigs covering ~78 Mb of the Arabidopsis genome. On average, these contigs are 12-fold deep in coverage. Thus, the contigs encounter one BAC approximately every 8 kbp. Different areas of the genome exhibit more or less BAC coverage. Nonetheless, the Arabidopsis physical map database is a valuable resource for viewing BAC contigs and building sequence ready maps. We offer this resource to the community.
- Once you are at the main page of the physical map database, you enter a BAC name and a static ACEDB-style GIF image is returned. At Washington University, TAMU or T BACs are entered as M, and IGF or F BACs are entered as I and leading zeroes are required. For example, enter I005I10 for BAC F5I10 - use capital letters. Returned is the GIF image of BAC contig 19, containing 452 clones including F5I10, from the top arm of chromosome IV. Information about the contig is presented in a blue bar across the top.
- Warning! The data presented here need to be confirmed. We are still editing the contigs and their associated annotation. Some BACs and contigs are ambiguous in their genetic marker assignment. These are being resolved and will change in the next few weeks. In addition, as the editing process continues and contigs are joined, the contig number to which a BAC is assigned may change.
