Abstract: The present invention provides for selection of bovine animals that will display phenotypes associated with increased rates of growth. These phenotypes include hot carcass weight, average daily gain, shipping weight, end of test rib eye area, and adjusted weaning weight which is a measure of post-natal growth, based on the knowledge of their CRH, POMC and MC4R genotypes. The predictive value comes from the discovery that certain single nucleotide polymorphisms (SNPs) in these genes are linked to higher growth rate phenotypes. Specifically, the phenotypes that correlated with specific SNP's are end-of-test rib-eye area, adjusted weaning weight, average daily gain, shipping weight and hot carcass weight. The invention also provides novel kits that can be used in making the determination of these genotypes.

Abstract: Methods for using cyclin-dependent kinase (CDK) inhibitor genes, or anti-sense constructs complementary to such genes, to modify the growth and development of plant cells and organs are disclosed. Also provided are methods of modifying the development of plant cells and plants by transforming plant cells with nucleic acids encoding cyclin-dependent kinase inhibitor polypeptides, or anti-sense constructs complementary to such nucleic acids, to produce transformed plant cells, and then culturing the plant cells or regenerating a plant under conditions wherein the cyclin-dependent kinase inhibitor, or the anti-sense construct, is expressed. A variety of CDK inhibitor genes, and corresponding anti-sense constructs, are disclosed for use in a variety of plants. The nucleic acid encoding the cyclin-dependent kinase inhibitor may be operably linked to a tissue-specific promoter. Other provided aspects are modified transgenic plants and plant tissues.

Abstract: An apparatus for measuring the displacement of visco-elastoplastic media below a surface thereof comprises an upper plate mounted such that a displacement force exerted on the top surface thereof will move the upper plate a displacement distance downward toward a base. Guides maintain the upper plate and the base in alignment such that movement is along a displacement axis. A calibrated bias element exerts a calibrated bias force resisting movement of the upper plate toward the base. A displacement measuring device measures the displacement distance, and is operative to generate a movement signal corresponding to the displacement distance. A data acquisition system is operative to receive and record the movement signal, and calculate the displacement force exerted on the top surface of the upper plate required to move the upper plate the displacement distance against the calibrated bias force.
