  • Title: Genetic modulation of ethylene biosynthesis and signaling in plants.
    Author: Czarny JC, Grichko VP, Glick BR.
    Journal: Biotechnol Adv; 2006; 24(4):410-9. PubMed ID: 16524685.
    Abstract:
    With the isolation and characterization of the key enzymes and proteins, and the corresponding genes, involved in ethylene biosynthesis and sensing it has become possible to manipulate plant ethylene levels and thereby alter a wide range of physiological processes. The phytohormone ethylene is an essential signaling molecule that affects a large number of physiological processes; plants deprived of ethylene do not grow and develop normally. In a search for flexible on-off ethylene control, scientists have used inducible organ- and tissue-specific promoters to drive expression of different transgenes. Here, the various strategies that have been used to genetically engineer plants with decreased ethylene biosynthesis and sensitivity are reviewed and discussed.
