    摘要: The present invention provides recombinant promoters that drive tissue-specific expression, and transgenes comprising such recombinant promoters. Specifically, the invention provides transgenes comprising a recombinant promoter that drives tissue-specific expression of a heterologous nucleic acid molecule in a floral organ. The invention also provides methods for using such transgenes to produce a protein in a host cell or transgenic plant. The invention further provides methods for producing a transgenic plant that produces, for example, longer-lasting flowers, better fragrance, or better or longer-lasting color as compared to a wild type plant.

    摘要: The present invention relates to the altering or controlling inhibition of gene expression in a cell using a methodology involving a dsRNA. The use of the method in plants and plant cells has been found to be particularly beneficial. For example the inhibition of a hormone signaling gene in a plant, such as the EIN2 gene, permits the modulating of flower longevity in the selected plant. This is accomplished by using our RNAi technology in inhibiting the expression of an ethylene-modulated gene or an ethylene signaling gene in plants and plant cells. This method provides for the use of RNAi technology in inhibiting the expression of a hormone signaling gene in a plant, particularly in the floral parts of a plant. Thus, one can modulate flower longevity in a plant.
