Bovine Genome Project

About the Project

The BCM-HGSC sequenced and analyzed the bovine genome (Bos taurus). The initial bovine genome assembly and analysis and the study of cattle genetic history were published April 24, 2009. Later efforts centered around finishing the Y chromosome. The most recent efforts to improve the genome are using Pacific Biosciences long-read data. We have produced 19-fold coverage of long read sequence data and combined these with the existing genome assembly using the PBJelly2 software. A de novo genome assembly using higher coverage PacBio data is planned in collaboration with Timothy Smith and Juan Medrano.

The source of the BABovineC 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 (for the Sanger data) and spleen (for the PacBio data) 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.

Current improvement efforts are funded by the United States Department of Agriculture National Institute of Food and Agriculture (2013-67015-21228) with support from the National Human Genome Research Institute (NHGRI U54 HG003273), which is part of the National Institutes of Health (NIH). Past funding for this project was also provided by: NHGRI U54 HG003273 as well as the U.S. Department of Agriculture's Agricultural Research Service and Cooperative State Research, Education, and Extension Service (USDA ARS Agreement No. 5 9-0790-3-196 and CSREES Agreement No. 2004-35216-14163); the state of Texas; Genome Canada through Genome British Columbia, The Commonwealth Scientific and Industrial Research Organization of Australia (CSIRO); Agritech Investments Ltd., Dairy Insight, Inc. and AgResearch Ltd., all of New Zealand; the Robert J. Kleberg, Jr. and Helen C. Kleberg Foundation; and the National, Texas and South Dakota Beef Check-off Funds.
