Letter from Chancellor Ronnie D. Green

Ronnie D. Green

This fall, the university is entering the home stretch of a three-year process to reaffirm its accreditation. Now, we’re asking you to help bring this effort across the finish line. In the coming weeks we are hosting forums open to faculty, staff …

The Genome Sequence of Taurine Cattle: A Window to Ruminant Biology and Evolution

Christine G. Elsik, Ross L. Tellam, Kim C. Worley, Richard A. Gibbs et autres

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are …

Genome-Wide Survey of SNP Variation Uncovers the Genetic Structure of Cattle Breeds

Richard A. Gibbs, Jeremy F. Taylor, Curtis P. Van Tassell, W. Barendse et autres

The imprints of domestication and breed development on the genomes of livestock likely differ from those of companion animals. A deep draft sequence assembly of shotgun reads from a single Hereford female and comparative sequences sampled from six additional breeds were used …

A physical map of the bovine genome

W. M. Snelling, Readman Chiu, Jacqueline E. Schein, Matthew Hobbs et autres

BACKGROUND: Cattle are important agriculturally and relevant as a model organism. Previously described genetic and radiation hybrid (RH) maps of the bovine genome have been used to identify genomic regions and genes affecting specific traits. Application of these maps to identify influential …

Transmitochondrial differences and varying levels of heteroplasmy in nuclear transfer cloned cattle

Stefan Hiendleder, S. M. Schmutz, G. Erhardt, Ronnie D. Green et autres

To assess the extent of cytoplasmic genetic variability in cloned cattle produced by nuclear transplantation procedures, we investigated 29 individuals of seven male cattle clones (sizes 2-6) from two different commercial sources. Restriction enzyme and direct sequence analysis of mitochondrial DNA (mtDNA) …

Just How Important Are Carcass EPDs

Ronnie D. Green

The National Beef Quality Audit, conducted by Colorado State, Texas A&M and Texas Tech Universities in 1992, was a "wake-up" call to the beef cattle industry. The results of the audit of the slaughter cattle population, conducted in 28 plants from across …
