  • Patent number: 5447858
    Abstract: A plant heat shock promoter has been isolated from soybean, sequenced and shown to induce gene expression in response to a temporary heat shock. This invention utilizes the disclosed plant heat shock promoters for the construction of promoter/structural gene chimeras which are expressible in plant cells in response to heat shock. The reporter gene .beta.-galactosidase was expressed transiently in response to a heat shock signal. Further, this invention permits application of heat shock inducible chimeras as a detection method for successful transformation of plant cells.

  • Patent number: 5439526
    Abstract: Disclosed and claimed is a rapid, simple process for fractionating wheat flour into components comprising protein concentrates and prime starch. The claimed method utilizes minimal water and produces a low waste water load. Flour and liquid are mixed to form a dough. Additional liquid is added to the dough and the dough and liquid are vigorously dispersed. The dispersion is centrifuged and forms distinct fractions-layers that are separated for the recovery of vital gluten and prime starch.

  • Patent number: 5432079
    Abstract: Methods for the isolation of mutant rhizobial strains with improved competition of nodulation (Comp.sup.+) is presented. Mutants are selected for constitutive expression of inducible nod genes (in the absence of inducer) and screened for hyperinduction of nod genes in the presence of inducer. Mutants which are defective in nodulation or in symbiotic nitrogen fixation are eliminated from further testing. Selections for constitutive nod expression and for hyperinduction of nod genes are facilitated by the use of plasmid carrying a selectable marker fused to an inducible nod gene and a plasmid carrying a reporter gene fused downstream of an inducible nod gene. The methods exemplified are particularly useful for the isolation and identification of Comp.sup.+ mutants of Bradyrhizobium japonicum.

  • Patent number: 5427786
    Abstract: The subject invention concerns Bacillus thuringiensis microbes with activity against select coleopteran pests e.g., Diabrotica sp., Hypera sp., and various flea beetles. For example, the B.t. isolates of the invention are active against alfalfa weevils--AW (Hypera brunneipennis), rape flea beetles--RFB (Phyllotreta cruciferae) and corn rootworms--CRW (Diabrotica undecimpunctata undecimpunctata). Thus, these microbes can be used to control these pests. Further, genes encoding toxins active against these pests can be isolated from the B.t. isolates and used to transform other microbes. The transformed microbes then can be used to control susceptible coleopteran pests.
