  • Publication number: 20210002657
    Abstract: Methods of detecting the impacts on plant health attributable to the presence of one or more agronomically important polypeptides of interest in a transgenic plant are disclosed. The methods involve transforming plants or plant cells with nucleic acid sequences encoding proteins of agronomically important traits. The transformed plants or plant cells expressing the nucleic acid sequences encoding the proteins of agronomically important traits are compared to transformed plants or plant cells expressing a neutral control gene to detect the impacts on plant health attributable to the presence of the one or more agronomically important polypeptides of interest.

  • Patent number: 8022275
    Abstract: The present disclosure provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions include a novel nucleotide sequence for a tissue-preferred maize promoter. A method for expressing a heterologous nucleotide sequence in a plant using the promoter sequence disclosed herein is provided. The method comprises stably incorporating into the genome of a plant cell a nucleotide sequence operably linked to the tissue-preferred promoter of the present invention and regenerating a stably transformed plant that expresses the nucleotide sequence.
