Plant hormones (also known as phytohormones) are signal molecules produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of growth and development, from embryogenesis, the regulation of organ size, pathogen defense, stress tolerance and through to reproductive development. Unlike in animals (in which hormone production is restricted to specialized glands) each plant cell is capable of producing hormones. The term 'phytohormone' was coined by Went and Thimann and used in the title of their book in 1937.
Materials and methods for tissue-specific targeting of ethylene insensitivity in transgenic plants
The subject invention concerns materials and methods for controlling agricultural traits in plants that are mediated by the plant hormone ethylene. One aspect of the invention concerns a polynucleotide that comprises a sequence encoding a mutant ethylene receptor that is operably linked to a regulatory sequence that drives expression of the mutant receptor in a tissue-specific manner. In an exemplified embodiment, the mutant receptor sequence is an etr1-1 sequence, or a functional fragment or variant thereof, and the regulatory sequence is a promoter sequence from a cotton chitinase gene that can promote expression of the mutant ethylene receptor in abscission zone tissue of a plant. The subject invention also concerns plants and plant tissue transformed with the polynucleotide of the subject invention. Plants expressing the polynucleotide of the subject invention do not drop their flowers in response to exposure to ethylene.
