Syngenta tomato UHD Map • ~ 2,000 genetic markers mapped to single a bin • ~6,000 genes mapped to a single bin
Syngenta Tomato Physical Map Coverage 1 2 3 4 5 6 7 8 9 10 11 12 = FPC Coverage
The Data • FPC Contig Number – From AGI Build • Zamir Introgression Line bin position • Chromosome • cM location (if possible) on EXPEN 2000 genetic map • All BACs in anchored FPC contig
Some Physical Map Stats • Number of clones in contigs: 64,918 • Number of contigs:6,794 • Number of anchored contigs: 763 • Number of clones in anchored contigs: 14,256 • Average insert size: 117KB • Genome size: 950MB • Genome coverage of clones in contigs: 8X • Megabases of tomato genome in anchored contigs: 208 = 26%
We can do more…. • Manual gap filling • Add our internal SSRs to and anchor more BAC contigs. • Hybridize arrayed BAC filters with our markers?
Questions we don’t know the answers to: • How are BACs chosen for sequencing? • BACs that are directly linked to markers (hybridization, BAC ends) • Are minimum tilling paths chosen from fingerprint overlaps? • How are neighboring FPC contigs chosen? • Looks like the Sanger Center has fingerprinted a Mbo1 BAC library and and done an FPC build with clones from both libraries. • Are other sequncing groups using this build or the AGI build? • Were the Mbo1 clones hybridized to markers? • Was BAC end sequencindone on the Mbo1 library?
