2081319 9116417 PCTABS00008 Novel compositions and methods are provided for modifying the ethylene levels of plant tissues of interest, including petal, leaf and various fruit tissues. The methods involve transforming a plant cell of interest with an expression cassette functional in a plant cell comprising a transcriptional and translational initiation regulatory region, joined in reading frame 5' to a DNA sequence encoding an enzyme capable of modulating the production of ethylene, and translational and transcriptional termination regions. Expression of the enzyme provides for a decrease in ethylene production as a result of altered concentrations of substrate for enzyme involved in ethylene biosynthesis. Of particular interest is the selective control of ethylene production in plant tissues such as flowers, fruit and leaves, especially to inhibit dramatic increases in ethylene production related to fruit and tissue senescence, abscission and/or ripening.
