  • Patent number: 7868224
    Abstract: Compositions and methods for suppressing the shade-avoidance response of plants and improving plant yield are provided. Compositions of the invention include an early flowering 3 (ELF3) maize gene, the promoter for this gene, an Arabidopsis basic helix-loop-helix transcription factor (bHLH-041), and fragments and variants thereof. The ELF3 promoter sequence is useful for driving expression of polynucleotides of interest in a plant. The ELF3 and bHLH-041 sequences of the invention, or variants and fragments thereof, are provided in expression cassettes for use in manipulating expression of the ELF3 and bHLH-041 genes. By increasing expression of ELF3 and/or suppressing expression of bHLH-041, the methods of the invention provide for altered response of a plant to light quality and suppression of the high-density-invoked survival mode of development. The invention thus provides methods for growing crop plants at high population densities for yield enhancement.

  • Patent number: 7745184
    Abstract: The present invention provides a microorganism useful for biologically producing 1,3-propanediol from a fermentable carbon source at higher yield than was previously known. The complexity of the cofactor requirements necessitates the use of a whole cell catalyst for an industrial process that utilizes this reaction sequence to produce 1,3-propanediol. The invention provides a microorganism with disruptions in specified genes and alterations in the expression levels of specified genes that is useful in a higher yielding process to produce 1,3-propanediol.

  • Publication number: 20090048428
    Abstract: Peptide tags, referred to here as inclusion body tags, are disclosed and are useful for the generation of insoluble fusion peptides. The fusion peptides comprise at least one inclusion body tag operably linked to a peptide of interest. Expression of the fusion peptide in a host cell results in a product that is insoluble and contained within inclusion bodies in the cell and/or cell lysate. The inclusion bodies may then be purified and the protein of interest may be isolated after cleavage from the inclusion body tag.

  • Patent number: 7288607
    Abstract: This invention relates to a primer composition having a low VOC content useful in the manufacture of automobiles and trucks in which the film forming binder contains: a) a cycloaliphatic or polycycloaliphatic epoxy compound; b) an alkoxy silane or silicate reactive diluent; and, c) a curing catalyst to catalyze the reaction between (a) and (b). These primers are characterized in that the curing or crosslinking reaction is presumably based, at least in part, on a ring opening polymerization reaction between the epoxy structures of (a) and silanol groups formed on (b) in the presence of atmospheric moisture and acid. Curing chiefly utilizing a ring opening reaction of the forgoing epoxy structures with the forgoing reactive diluents not only avoids volatile compounds from being generated and released into the atmosphere during the curing process, but also keeps the viscosity low enough for practical application such as by spraying.
