  • Title: A compound from smoke that promotes seed germination.
    Author: Flematti GR, Ghisalberti EL, Dixon KW, Trengove RD.
    Journal: Science; 2004 Aug 13; 305(5686):977. PubMed ID: 15247439.
    Abstract:
    Exposure of seeds to aerosol smoke or crude smoke extracts stimulates the germination of a number of fire-dependent and fire-independent plant species. We now report the identity of a germination-promoting compound present in plant- and cellulose-derived smoke. The structure of this compound, deduced from spectroscopic analysis and confirmed by synthesis, was shown to be that of the butenolide 3-methyl-2H-furo[2,3-c]pyran-2-one (1). Here we show that 1 promotes germination of a number of plant species at a level similar to that observed with plant-derived smoke water.
