- Title: "A whole-genome assembly of the cow, Bos taurus"
- Authors:
Steven Salzberg Aleksey Zimin Arthur Delcher Liliana Florea David Kelley Finian Hanrahan Guillaume Marcais Geo Pertea Michael Roberts Michael Schatz Curt Van Tassell James Yorke Poorani S.
- Assembler:
Celera Assembler and UMD Overlapper.
- Sequencing Center :
Baylor College of Medicine.
- Source of DNA used for sequencing:
The source of the BAC library DNA was Hereford bull L1 Domino 99375, registration number 41170496. Dr. Michael MacNeil's laboratory, USDA-ARS, Miles City, MT provided the blood. The DNA for the whole genome shotgun sequences was provided by Dr. Timothy Smith's laboratory, U.S. Meat Animal Research Center, Clay Center, NE from white blood cells from L1 Dominette 01449, American Hereford Association registration number 42190680 (a daughter of L1 Domino 99375). A skin cell fibroblast cell line from the same animal is available from Dr. Carol Chitko-McKown's laboratory, although there is no sequence from that cell line.

Problems:
1: Vectors
- Q: Which vectors are the most frequent?
- A: align UMD2 vctor contaminants to UniVec_core:
- 28051(29113 maxmatch) out of 33540 align : UniVec_Core-UMD2.vector.ref_hits
- pBR322, Ecoli_lac*, pSacBII ...
- pBACe3.6 (U80929.2:11415-11517): CONTAINED
- 5489(4427 maxmatch) out of 33540 don't align (4373 are 100+bnp, 11 are 500+bp) ; some aligned by megablast to 100 NCBI mostly vector sequences Bos_taurus.UMD2.vector.no_UniVec_Core.no_Ecoli.all.blastn_hits
2: Ecoli
- There are 22 Ecoli strains * 3 Ecoli K12 substarins
- MG1655 is the 1st one completed, DH10B and W3110 have been recently(?) completed
- Contain unique seqs as long as 28K

- out of 746 UMD2 Ecoli seqs, 636(723 maxmatch) aligned to Ecoli.all
3: Other
- contaminants: 289 ; mostly Ecoli
- phage: 16 ; 1 aligns to Ecoli, all <1108bp
- IS: 398; all <1711 bp; 14 align to Ecoli.all & 1 to UniVec_Core; few were NCBI blasted aligned to mammals !!!
