  • Patent number: 5451514
    Abstract: The synthesis of lignin by plants is controlled by transformation of the plant genome with a recombinant gene construct which contains the gene specifying an enzyme critical to the synthesis of a lignin precursor, which gene may be in antisense orientation so that it is transcribed to mRNA having a sequence complementary to the equivalent mRNA transcribed from the endogenous gene thus leading to suppression of lignin synthesis. If the recombinant gene has the lignin enzyme gene in normal, or "sense" orientation, increased production of the enzyme may occur when the insert is the full length DNA but suppression may occur if only a partial sequence is employed.

  • Patent number: 5449764
    Abstract: DNA clones, e.g. P13-B, comprising at least part of a gene derived from peach that encodes ethylene-forming enzyme. Such clones may comprise DNA constructs including plant promoters capable of expressing RNA in plant cells. Such constructs may be used to inhibit production of ethylene-forming enzyme in transformed plants, and thereby to produce slower-ripening fruit, particularly peaches. The clones may be obtained by PCR using specific oligo-nucleotide primers.

  • Patent number: 5449658
    Abstract: The growth of algae, fungi and pathogenic organisms in commercial and recreational waters, such as cooling towers, swimming pools and spas, may be controlled by adding to the water a primary sanitizing agent, preferably poly(hexamethylene biguanide) ("PHMB"), and a potentiating adjuvant comprising a calcium ion-chelating agent, preferably ethylenediamine tetraacetic acid ("EDTA"), in amounts such that the adjuvant renders the composition algicidal and fungicidal in water. The water may be further treated with a peroxy salt as a backup agent, preferably sodium perborate, or the calcium ion-chelating agent and peroxy salt may be combined as a shock treatment to water being treated with the primary sanitizing agent.
