20090183280 | Transgenic Plants Modified for Reduced Cadmium Transport, Derivative Products, and Related Methods - Various embodiments are directed to transgenic plants, including transgenic tobacco plants and derivative seeds, genetically modified to impede the transport of Cadmium (Cd) from the root system to aerial portions of transgenic plants by reducing the expression levels of HMA-related transporters. Various embodiments are directed to transgenic tobacco plants genetically modified to stably express a RNAi construct encoding RNAi polynucleotides that enable the degradation of endogenous NtHMA RNA variants. Reduced expression of NtHMA transporters in transgenic plants results in substantially reduced content of Cadmium (Cd) in the leaf lamina. Various consumable products that are substantially free or substantially reduced in Cd content can be produced by incorporating leaves derived from transgenic tobacco plants modified to reduce the expression of NtHMA transporters. | 07-16-2009 |

20140283165 | DEVELOPMENT OF TOBACCO VARIETIES WITH NO OR SIGNIFICANTLY REDUCED ANATABINE CONTENT - A process for producing a reduced tobacco-specific nitrosamine (TSNA) tobacco plant comprising reducing and/or eliminating anatabine biosynthesis in wild-type tobacco plant. In addition, use of such plants for discovery of molecular markers that are closely linked with genes required for anatabine biosynthesis and for discovery of genes required for anatabine biosynthesis. In addition, a smoking composition, a smoking article and a smokeless tobacco oral delivery product contain the tobacco material. | 09-18-2014 |
