The present invention is directed to a transgenic plant and a method for producing the same. In particular, the present invention is directed to a transgenic plant or a plant cell in which a nucleic acid molecule encoding an m.sup.6A demethylase is introduced, wherein said m.sup.6A demethylase has the following two domains: i) N-terminal domain (NTD) having the function of AlkB oxidation demethylase; and ii) C-terminal domain (CTD). The present invention is also directed to a method for producing said plant, comprising introducing a nucleic acid molecule encoding an m.sup.6A demethylase into a regenerable plant cell, and regenerating a transgenic plant from the regenerable plant cell.

The present invention provides recombinant DNA constructs, vectors and molecules comprising a polynucleotide sequence encoding a florigenic FT protein operably linked to a vegetative stage promoter, which may also be a meristem-preferred or meristem-specific promoter. Transgenic plants, plant cells and tissues, and plant parts are further provided comprising a polynucleotide sequence encoding a florigenic FT protein. Transgenic plants comprising a florigenic FT transgene may produce more bolls, siliques, fruits, nuts, or pods per node on the transgenic plant, particularly on the main stem of the plant, relative to a control or wild type plant. Methods are further provided for introducing a florigenic FT transgene into a plant, and planting transgenic FT plants in the field including at higher densities. Transgenic plants of the present invention may thus provide greater yield potential than wild type plants and may be planted at a higher density due to their altered plant architecture.

A method of producing a stably transformed corn plant in a single container is demonstrated. This method allows for the automation of the transformation process and reduces labor, material, and ergonomic costs associated with traditional plant tissue culture systems.

Methods and materials for modulating low light and/or shade tolerance, and red light specific responses in plants are disclosed. For example, nucleic acids encoding low light and/or SD+EODFR-tolerance polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased low light and/or SD+EODFR tolerance. In addition, methods and materials involved in increasing UV-B tolerance in plants and methods and materials involved in modulating biomass levels in plants are provided.

Transgenic plants having enhanced yield and having enhanced seed yield are disclosed. The transgenic plants are transformed with a transgenic polynucleotide encoding one or more metabolic enzymes. The metabolic enzymes can be from any biological source. The transgenic polynucleotide(s) comprises a nucleic acid sequences encoding the metabolic enzymes under the control of functional plant promoters, the one or more metabolic enzymes are targeted to the plastids by the addition of plastid targeting signals. Optionally the functional plant promoters are seed specific promoters and the metabolic enzymes are targeted to the plastids by the addition of plastid targeting peptide heterologous to the metabolic enzymes. Methods of making the transgenic plants and transgenic polynucleotides are disclosed. The magnitude of the increases in seed yield achieved with these transgenic plants are simply unprecedented.

This disclosure provides tobacco plants that exhibit altered photosynthesis as well as methods of making and using such plants.

The invention relates to methods of producing a desired phenotype in a plant by manipulation of gene expression within the plant. The method relates to means which inhibit the level of PK220 gene expression or activity, wherein a desired phenotype such as increased water use efficiency relative to a wild type control plant. The invention also relates to nucleic acid sequences and constructs useful such methods and methods of generating and isolating plants having decreased PK220 expression or activity.

The present disclosure includes methods and compositions for improving leaf quality in low-alkaloid tobacco plants, e.g., by combining inducible promoters and non-coding RNAs for suppression of an ornithine decarboxylase (ODC) gene. Also provided are low alkaloid tobacco plants with normal, suppressed, or otherwise altered polyamine levels. Further provided are tobacco plants with altered total alkaloid, nicotine levels, commercially acceptable leaf grade, their development via breeding or transgenic approaches, and production of tobacco products from these tobacco plants.
