  • Title: Stimulation by Erwinia carotovora of the synthesis of ethylene in cauliflower tissue.
    Author: Lund BM, Mapson LW.
    Journal: Biochem J; 1970 Sep; 119(2):251-63. PubMed ID: 5488914.
    Abstract:
    The synthesis of ethylene by cauliflower floret tissue was increased when the tissue was inoculated with the soft-rot bacterium Erwinia carotovora. This effect was clearly associated with the production of pectic enzymes by the micro-organism. These enzymes, acting together with the plant enzymes, stimulated the production of ethylene from methionine. The increased synthetic activity was due to the release and increased activity of a glucose oxidase enzyme apparently attached to plant cell-wall material and liberated by the action of pectic enzymes of the bacterium.
