St. Petersburg, FL — Florida Genetics, LLC, is pleased to announce the issuance of US Patent No. 7,129,343, a new genetic engineering technique for controlling gene expression in plants, animals and many microbes. This patent describes the newly invented Bidirectional Dual Promoter Complex (BDPC), which facilitates genetic engineering by simultaneously coordinating the expression of multiple genes in a single, easily manipulated, genetic unit. The BDPC provides dramatic improvement over mono-directional promoter systems that have been used in all previous eukaryotic genetic engineering systems and is the most efficient method known for up- or down-regulating expression of virtually any targeted gene or genes. Genes of interest can be readily arranged in the BDPC, which is then inserted into a target organism’s chromosomes using standard biotechnological methods. In this way new traits, such as disease resistance or protein production, can be readily created.
