20140033364 | Modification of Plant Development and Morphology - A method of modifying morphology in a plant by introducing into a plant at least one chimaeric gene having a promoter sequence operably associated with a nucleic acid sequence, the promoter sequence being operable to direct expression in specific cells of the plant and the nucleic acid sequence encoding at least one gene product capable of altering the metabolism of or causing death of the specific cells and/or nearby cells. In particular, the promoter sequence is operable to direct expression in lateral bud or lateral shoot and the nucleic acid encoding at least one gene product capable of disrupting the metabolism of or causing the death of the lateral bud or lateral shoot of nearby cells. Preferably the promoter sequence has the sequence shown as SEQ ID No. 1 or SEQ ID No. 7 or SEQ ID No. 4, or a part thereof capable of regulating expression of a gene, or a sequence having at least 60%, preferably at least 75%, homology to SEQ ID No. 1 or SEQ ID No. 7 or SEQ ID No. 4 and being capable of regulating expression of a gene. | 01-30-2014 |
20120199144 | Transgenic Plants - The invention provides transgenic plants, specifically tobacco plants, which accumulate the amino acid threonine in their leaves. The biosynthetic pathway leading to production of threonine is tightly regulated, and previous attempts to achieve a transgenic plant which overproduces threonine has compromised the fitness of the plants. This invention has overcome these difficulties and found a method of increasing the level of threonine in plant leaves above the corresponding wild type level without compromising plant fitness, comprising altering plant metabolism to achieve increased production of threonine after the initiation of leaf senescence. This invention involves a genetic construct comprising a senescence specific promoter operably linked to a coding sequence encoding a polypeptide having threonine insensitive aspartate kinase activity. | 08-09-2012 |
