  • Plant promoter
    Publication number: 20040101841
    Abstract: Promoter sequences identified in the genomic clone of PHSacc49 provide technology by which expression of a sense or antisense genes may be driven in transgenic plants. Sense and introduced antisense genes expression can be regulated by the same endogenous promoter to the same extent. Moreover, as a promoter native to geranium, its activity will be influenced by endogenous and exogenous signals in the same fashion and regulation of ethylene levels in plants would represent a condition that is natural to the plant.

  • Partial gene sequence from pelargonium to control ethylene levels in geraniums
    Patent number: 6723839
    Abstract: A novel ACC synthase gene in geranium PHSacc-25. PHSacc-25 was identified by amplifying isolated mRNA using polymerase chain reaction, the resulting cDNAs were cloned into a plasmid, positive clones were isolated, and the cDNA insert was partially sequenced. A portion of the DNA sequence encoding for the enzyme ACC synthase in geranium plants (specifically from Pelargonium hortorum cv Sincerity) was identified. The cDNA sequence corresponds to a gene which may be important in the control of ethylene production.

  • 1-aminocyclopropane-1-carboxylate synthase gene from Rosa to control ethylene levels in roses
    Publication number: 20020083484
    Abstract: A gene which encodes an ACC synthase is identified for the rose plants, specifically Rosa (cardinal red). This gene is shown as modified to achieve a transgenic plant which resists wilting and the like as a result of reduced ethylene production. This alteration is reproduced by the transformed plant. Isolation of high quality mRNA is achieved through use and adaptation of a 2-butoxyethanol precipitation technique using large amount of initial tissue in order to achieve critical mass for precipitation.

  • 1-Aminocyclopropane-1-carboxylate synthase genes from rosa to control ethylene levels in roses
    Patent number: 6184449
    Abstract: A gene which encodes an ACC synthase is isolated from rose plants, specifically Rosa (cardinal red). This gene is modified for expression in transgenic plants. Isolation of high quality mRNA for gene isolation is achieved through use and adaptation of a 2-butoxyethanol precipitation technique using large amount of initial tissue in order to achieve critical mass for precipitation.

  • 1-aminocyclopropane-1-carboxylate synthase genes from pelargonium
    Patent number: 5824875
    Abstract: Genes which encode ACC synthase are identified for the geranium plant, specifically Pelargonium x hortorum cv sincerity. These genes are shown as modified to achieve a transgenic plant which resists wilting and the like as a result of reduced ethylene production. This alteration is reproduced by the transformed plant. Isolation of high quality mRNA is achieved through use and adaptation of a 2-butoxyethanol precipitation technique using large amount of initial tissue in order to achieve critical mass for precipitation.
