Pseudomonas syringae pv. tomato str. DC3000
Data
Originally sequenced and finished at TIGR: published Sept 2003
NCBI
AA: no assembly TA 80,959 reads Genome Project Taxonomy TaxId=223283
Chromosome + 2 plasmids:

Little similarity between the chromosome and plasmids. The 2 plasmids share a significant amount of DNA; see /fs/szasmg2/Bacteria/Pseudomonas_syringae/Data/nucmer/NC_004633-NC_004632.png

* Solexa 3 lanes;
* 454 shotgun 1/4 Plate (250bp read);
* 454 paired ends 1/4 Plate :
* contain a 44 bp linker in the middle
* the linker sequence is: GTTGGAACCGAAAGGGTTTGAATTCAAACCCTTTCGGTTCCAAC
* there are some (not many) 454 paired end sequences that contain multiple instances of the linker (tandem): Example EUEIEUN01ANUGL_length=128_xy=0154_1891
Quality values are missing for all data sets!!!
I assigned default qual=3 to all the base (.frg & .afg files)
UNC sequence data: (not avail any more?)
http://biology622.dhcp.unc.edu/~labweb/DCData/
UNC (e-mail):
* Theoretical minimum number of contigs we can obtain is 268 (our reads fail to cover 269 nucleotides). * Our de novo assembly spans the genome in 853 contigs totaling 6,313,026 bp. * 98.7% of the genome is covered by a contig; * 84% of the genome is covered by contigs 10,000 bp or greater. * The average gap size between contigs is 98 bp; * average contig size 7401 bp. * The N50 = 37,444 bp. * Our largest BAMBUS "scaffold" is 2,565,761 bp
