    摘要: 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.
