Abstract:
Provided are constructs and methods for expressing multiple genes in plant cells and/or plant tissues. The constructs provided comprise at least one bidirectional promoter link to multiple gene expression cassettes. In some embodiments, the constructs and methods provided employ a bidirectional promoter based on a minimal core promoter element from a Zea mays Ubiquitin-1 aerie or a functional equivalent thereof. In some embodiments, the constructs and methods provided allow expression of genes between three and twenty.

Provided are constructs and methods for expressing multiple genes in plant cells and/or plant tissues. The constructs provided comprise at least one bi-directional promoter linked to multiple gene expression cassettes, wherein the bi-directional promoter comprises a functional promoter nucleotide sequence from Sugar Cane Bacilliform Virus promoter. In some embodiments, the constructs and methods provided employs a bi-directional promoter based on a minimal core promoter element from a Zea mays Ubiquitin-1 gene, or a functional equivalent thereof, and nucleotide sequence elements from a Sugar Cane Bacilliform Virus promoter. In some embodiments, the constructs and methods provided allow expression of genes between three and twenty.
Abstract:
Provided herein are herbicidal compositions comprising a mixture comprising (a) a 2,4-D-choline salt and (b) a salt of N-(phosphonomethyl)glycine (glyphosate). The compositions provide synergistic weed control of undesirable vegetation in areas including, but not limited to, non-crop, fallow-bed, perennial crops, tree, vine and fruit orchards, and plantation crops.
Abstract:
The subject invention provides novel plants that are not only resistant to 2,4-D, but also to pyridyloxyacetate herbicides. Heretofore, there was no expectation or suggestion that a plant with both of these advantageous properties could be produced by the introduction of a single gene. The subject invention also includes plants that produce one or more enzymes of the subject invention “stacked” together with one or more other herbicide resistance genes. The subject invention enables novel combinations of herbicides to be used in new ways. Furthermore, the subject invention provides novel methods of preventing the development of, and controlling, strains of weeds that are resistant to one or more herbicides such as glyphosate. The preferred enzyme and gene for use according to the subject invention are referred to herein as AAD-12 (AryloxyAlkanoate Dioxygenase). This highly novel discovery is the basis of significant herbicide tolerant crop trait and selectable marker opportunities.
Abstract:
An apparatus and method for determining the number of kernels on a sample cob are provided. In one embodiment, an image including a front region of the sample cob, and a back region of the sample cob displayed in at least one reflective surface are provided to an image processor that identifies the presence of kernels in the image and determines the number of kernels based on the identified presence of kernels in the image.
Abstract:
The Zea mays c.v. B73 Ubiquitin-1 (Z. mays c.v. B73 Ubi-1) promoter drives high levels of constitutive transgene expression in plants. Repeated use of the same Z. mays c.v. B73 Ubi-1 promoter in multi-gene constructs may also lead to gene silencing, thereby making transgenic products less efficacious. Provided are gene regulatory promoter elements, constructs, and methods for expressing a transgene in plant cells and/or plant tissues using gene regulatory elements from the Ubi-1 promoter of a different Zea species, Z. luxurians v1.
