Abstract: The present invention relates to the identification of single nucleotide polymorphisms (SNPs) in urotensin II (UTS2) and urotensin 2 receptor (UTS2R) genes and their associations with beef marbling score (BMS), ribeye area (REA), amounts of saturated (rSFA) and monounsaturated (rMUFA), and ?9 desaturase activity R2=16:1 to 16:0. The invention further encompasses methods and systems, including network-based processes, to manage the SNP data, haplotype data and other data relating to specific animals and herds of animals, veterinarian care, diagnostic and quality control data and management of livestock which, based on genotyping, have predictable meat quality traits, husbandry conditions, animal welfare, food safety information, audit of existing processes and data from field locations.

Abstract: A rapid and simple method of isolating heat stable proteinase inhibitor proteins from plant tissues such as potato tubers is disclosed. The method comprises three steps. Proteins from potato tubers are extracted in an aqueous/alcohol extraction medium to form an alcohol extract. The alcohol extract is heated to a first temperature then cooled to a second temperature to form an insoluble precipitate phase containing debris and a soluble phase that contains the heat stable proteinase inhibitor proteins. The heat stable proteinase inhibitor proteins are precipitated from the soluble phase by dialysis against a suitable dialysis medium. The precipitated proteins may include a single inhibitor protein, or a mixture thereof.

Abstract: Germacrene C synthase genes from Lycopersicon esculentum have been cloned and sequenced. Transgenic expression of germacrene C synthase in plants can result in beneficial and useful characteristics such as increased host resistance to pathogens and herbivores and altered flavor and odor profiles.
