摘要:
Genetic constructs capable of manipulating fructan biosynthesis in photosynthetic cells of a plant, said genetic constructs include a promoter operatively linked to a nucleic acid encoding a bacterial FT enzyme. These constructs can be used in modification of fructan biosynthesis in plants and, more particularly, for manipulating fructan biosynthesis in photosynthetic cells. The constructs can also be used for increasing plant biomass and, more particularly, for enhancing biomass yield and/or yield stability, including shoot and/or root growth in a plant, and for enhancing the productivity of biochemical pathways.
摘要:
The novel constructs and methods of this invention improve tolerance in plants to environmental stresses and senescence. Nucleic acids encoding a plant farnesyl transferase are described, as are transgenic plants and seeds incorporating these nucleic acids and proteins. Also provided are inhibitors of naturally-occurring farnesyl transferase which, when expressed, will enhance drought tolerance in the plants, improve resistance to senescence and modify growth habit.
摘要:
The present invention relates to unique strategies and constructs for altering expression of a desired gene by designing a construct designed to specifically target the non-transcribed 5 '-regulatory sequences of that gene.
摘要:
The present invention discloses transgenic plants having an altered level of NAP protein compared to that of a non-transgenic plant, where the transgenic plants display an altered leaf senescence phenotype relative to a non-transgenic plant, as well as mutant plants comprising an inactivated NAP gene, where mutant plants display a delayed leaf senescence phenotype compared to that of a non-mutant plant. The present invention also discloses methods for delaying leaf senescence in a plant, as well as methods of making a mutant plant having a decreased level of NAP protein compared to that of a non-mutant plant, where the mutant plant displays a delayed leaf senescence phenotype relative to a non-mutant plant. Methods for causing precocious leaf senescence or promoting leaf senescence in a plant are also disclosed. Also disclosed are methods of identifying a candidate plant suitable for breeding that displays a delayed leaf senescence and/or enhanced yield phenotype.
摘要:
The present invention provides a non-naturally occurring seed plant that is characterized by delayed seed dispersal due to ectopic expression of a nucleic acid molecule encoding an AGL8-like gene product. Further provided herein is a non-naturally occurring seed plant, such as an agl1 agl5 double mutant, that is characterized by delayed seed dispersal due to suppression of AGL1 and AGL5 expression in the seed plant. The invention also provides a substantially purified dehiscence zone-selective regulatory element, which includes a nucleotide sequence that confers selective expression upon an operatively linked nucleic acid molecule in the valve margin or dehiscence zone of a seed plant. Also provided by the invention are kits for producing a transgenic seed plant characterized by delayed seed dispersal, such kits containing a dehiscence zone-selective regulatory element.
摘要:
The present invention relates to the development of drought-resistant plants. This invention is directed to the preparation of transgenic plants that express a protein involved in cytokinin synthesis under the control of a senescence-inducible promoter.
摘要:
The present invention relates to unique isoforms of eukaryotic initiation Factor 5A ('eIF-5A'): senescence-induced eIF-5A; wounding-induced eIF-5A; and growth eIF-5A, as well as polynucleotides that encode these three factors. The present invention also relates to methods involving modulating the expression of these factors. The present invention also relates to deoxyhypusine synthase ('DHS'), polynucleotides that encode DHS, and methods involving modulating the expression of DHS.
