  • Publication number: 20160024513
    Abstract: A truncated stress-responsive transcription factor can be overexpressed without causing unfavorable pleiotropic effects. The truncation may result in deletion of a nuclear localization signal. The truncation may result in deletion of one or more regulatory motifs. The truncated transcription factor may be expressed under the control of a constitutive or tissue-preferred promoter. The transcription factor may be from maize.

  • Publication number: 20140298544
    Abstract: Variant phosphoenolpyruvate carboxylase (PEPC) genes are described. The encoded PEPC variants contain amino acid substitutions and have altered kinetic and/or regulatory properties with respect to wild-type PEPC. A variant PEPC gene may be expressed in a plant to improve one or more traits such as CO2 assimilation rate, water use efficiency, and yield.

  • Patent number: 6218600
    Abstract: The gene encoding a biotin carboxylase subunit of heteromeric ACCase has been isolated and sequenced. The cDNA sequence and deduced amino acid sequence is set forth in FIG. 1 and has been accorded GenBank Accession No. L38260. By controlling expression of the gene of the present invention, carboxylation of acetyl-CoA to produce malonyl-CoA may be controlled. Thus, by introducing constructs of the gene of the present invention in sense or anti-sense orientation, carboxylation of acetyl-CoA to produce malonyl-CoA may be increased or decreased. Consequently, fatty acid synthesis in plants and seeds which depends on malonyl-CoA in the plastid may also be controlled.
