  • Patent number: 8168860
    Abstract: A gene expression system for controllable expression of ethylene response in a plant cell includes an activation cassette comprising a DNA-binding domain that recognizes a response element; an ecdysone receptor ligand binding domain; and an activation domain; and a target cassette comprising an inducible promoter, which comprises, in operative association, the response element and a minimal promoter responsive to the activation domain. The inducible promoter controls the expression of a nucleic acid sequence that encodes a selected protein that modifies sensitivity to ethylene in the plant. Interaction among the components of the activation cassette and target cassette, when in a plant cell, in the presence of an inducing composition, modulates expression of the selected protein and selectively modulates ethylene sensitivity in the plant cell. This modulation in the expression of the protein is controlled by the timing, the concentration and the duration of the application of the inducing composition.

  • Patent number: 6971410
    Abstract: A portable drum dosing system includes an outer mast assembly extending generally horizontally from the main frame and includes a pair of legs disposed at an angle with respect to each other so that the legs may straddle and dispose the main frame near a drum. An upstanding post assembly extends upwardly from the main frame at the outer mast assembly. The post assembly includes a fixed guide post. An upper clamping mechanism is movably mounted to the fixed post for engaging the chime of a drum. A lifting mechanism controls the vertical movement of the upper clamping mechanism and of the stabilizing mechanism to permit a drum to be engaged by the transporter and then lifted and then conveyed from one location to another. An optional weight measuring device is movably mounted to the fixed post to permit the weight of the drum to be accurately determined.
