    Abstract: An improved method of purifying bean extract alpha-amylase material is disclosed. The materials purified by this process provide significantly more amylase inhibition than materials purified by other processes. In this process: (a) bean extract alpha-amylase material is suspended in an aqueous solution at a solution pH of from about 3.0 to about 3.5; (b) a preservative is added to the solution; (c) the solution is heated to about 175 F to about 195 F for from about 10 to about 120 seconds; (d) the solution is cooled to a temperature of from about 65 to about 85 F, and the solution is allowed to sit, under static non-agitated conditions, at a temperature with that defined range for from about 3 to about 24 hours to allow bean extract particles to settle out of solution; and (e) the particles are separated from the supernatant.

  • Patent number: 8614367
    Abstract: Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Promoter sequences and their essential regions are also identified. The nucleotide sequences are useful in mediating male fertility in plants. In one such method, the homozygous recessive condition of male sterility causing alleles is maintained after crossing with a second plant, where the second plant contains a restoring transgene construct having a nucleotide sequence which reverses the homozygous condition. The restoring sequence is linked with a hemizygous sequence encoding a product inhibiting formation or function of male gametes. The maintainer plant produces only viable male gametes which do not contain the restoring transgene construct. Increase of the maintainer plant is also provided by self-fertilization, and selection for seed or plants which contain the construct.

  • Patent number: 7759543
    Abstract: Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Promoter sequences and their essential regions are also identified. The nucleotide sequences are useful in mediating male fertility in plants. In one such method, the homozygous recessive condition of male sterility causing alleles is maintained after crossing with a second plant, where the second plant contains a restoring transgene construct having a nucleotide sequence which reverses the homozygous condition. The restoring sequence is linked with a hemizygous sequence encoding a product inhibiting formation or function of male gametes. The maintainer plant produces only viable male gametes which do not contain the restoring transgene construct. Increase of the maintainer plant is also provided by self-fertilization, and selection for seed or plants which contain the construct.

  • Patent number: 7557262
    Abstract: The invention provides polynucleotides, preferably synthetic polynucleotides, which encode processing enzymes that are optimized for expression in plants. The polynucleotides encode mesophilic, thermophilic, or hyperthermophilic processing enzymes, which are activated under suitable activating conditions to act upon the desired substrate. Also provided are “self-processing” transgenic plants, and plant parts, e.g., grain, which express one or more of these enzymes and have an altered composition that facilitates plant and grain processing. Methods for making and using these plants, e.g., to produce food products having improved taste and to produce fermentable substrates for the production of ethanol and fermented beverages are also provided.

  • Patent number: 7495152
    Abstract: SHE, a Starch Hydrolytic Enzyme active in maize endosperm (Zea mays), and the cDNA sequence encoding SHE are disclosed. The specificity of native, purified SHE is similar, in general terms, to previously known alpha-amylases. However, the activity of SHE toward amylopectin results in hydrolysis products that are distinctly different from those of other alpha-amylases. SHE, and its homologous equivalents in other plants such as rice, Arabidopsis, apple and potato, can be used in starch processing for generating different, e.g., larger sized, alpha-limit dextrins for industrial use, as compared to those generated by previously known alpha-amylases or other starch hydrolytic enzymes. In addition, modification of the expression of this enzyme in transgenic maize plants or in other transgenic organisms (including bacteria, yeast, and other plant species) can be useful for the generation of novel starch forms or altered starch metabolism.
