Abstract: The present invention provides a method to directionally clone any linear template DNA molecule into any linearized vector. The vector ends may be generated from any restriction enzyme cleavage. The method does not require a ligation step nor the use of carefully controlled conditions as is required with methods involving specific exonucleases alone. It has been determined that specific DNA polymerases are able to efficiently join one or more linear DNA molecules sharing ends with appropriate complementation.

Abstract: The present invention relates to a nitrogen-regulated GATA transcription factor gene required for sugar sensing and the modulation of the expression of this gene to modulate a characteristic in a plant. The GATA transcription factor of the present invention is involved in regulating sugar sensing in plants and its expression is influenced by nitrogen status. Increased expression of this or substantially similar genes can produce plants with improved nitrogen utilization and increased yield.

Abstract: The present invention relates to the identification of a single nucleotide polymorphism (SNP) within the bovine CAST locus encoding the calpastatin protein, wherein the allelic variation of the SNP is a G/C transversion associated with post-mortem muscle tenderness. The invention further relates to oligonucleotides useful in identifying the genotype of bovines as it relates to the CAST locus polymorphic site. The invention also encompasses computer-assisted methods and systems for improving the production efficiency for livestock having marketably tender meat using multiple data, and in particular the genotype of the animals as it relates to the CAST SNP.

Abstract: Disclosed are prion sensors that may be used as a diagnostic tool to diagnose TSE, or to detect PrPSc molecules, in biological and environmental samples, and methods for using these sensors. The prion sensor may comprise an acoustic sensor, such as a TSM sensor, coated with PrPC molecules, whose resonance characteristics change when contacted with a sample from an animal with TSE, or a sample comprising PrPSc molecules. Alternatively the prion sensor may comprise an optical sensor, such as an SPR sensor, coated with PrPC molecules, whose optical characteristics change when contacted with a sample from an animal with TSE, or a sample comprising PrPSc molecules. These changes provide both rapid detection and a quantitative assay for diagnosing TSE or for detecting PrPSc molecules.

Abstract: The present invention relates to novel inducible genes from alfalfa. These genes are highly induced following mechanical harvesting or wounding of alfalfa. The genes are useful for inducible production of heterologous proteins following harvesting.
Abstract: The present invention relates to a method for the production of a heterologous protein or peptide in a plant or a plant cell. The method involves providing a plant or a plant cell comprising construct comprising a harvest-inducible regulatory element that is operably linked with a heterologous coding sequence of interest, growing the plant or plant cell, and applying ABA or an analog thereof to the plant or plant cell, thereby inducing expression of the heterologous protein or peptide. If a plant is used, then following the application of ABA or an analogue thereof, the plant may be harvested.
