Genetic elements conferring flower petal-specific transgene expression

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.
