There are many different types of sustainable pest and weed control practices. 14.6 Alternatives to Conventional Agriculture They are guided by some general principles that include: Keeping insecticide, herbicide, fungicide, and fertilizer use to a minimum. Conserving soil and water resources. Staying ...
Glyphosate (Roundup) is a broad-spectrum, nonselective, systemic herbicide used to control annual and perennial plants.14.3 Agricultural Chemical Use Fungicides are used to protect 29、 agricultural crops from spoilage, to prevent the spread of disease, and to protect seeds from rotting in the ...
Seed stock designation Nbg-45 and Nbg-43 (both from initial sialic acid transgenic plant Nb88266-11) were surface sterilized using ethanol and sodium hypochlorite then plated onto Murashige and Skoog media plus Gamborg's vitamins plates supplemented with the herbicide Phosphinothricin. Phosphinothricin ...
One method of selection disclosed employs the Streptomyces bar gene introduced by microprojectile bombardment into embryogenic maize cells which were grown in suspension cultures, followed by exposure to the herbicide bialaphos. The methods of achieving stables transformation disclosed herein include tissue ...
29. A method of introducing a desired trait into the apomictic soybean plant of claim 22, said method comprising introducing a transgene conferring the desired trait, wherein the desired trait is selected from the group consisting of male sterility, herbicide tolerance, insect or pest resistance, ...
In particular embodiments, the host cell is a plant cell and the second exogenous nucleic acid sequence alters an agronomically useful phenotype selected from the group consisting of: a selectable or screenable marker, herbicide tolerance, increased yield, modified lignin content, altered cellulose or...
2. Description of the Related Art Recent advances in molecular biology have dramatically enhanced the ability of scientists to manipulate the germplasm of animals and plants. Genes controlling specific phenotypes, for example, particular polypeptides that lend insect, antibiotic and herbicide resistance, ...
Chemical-inducible promoters are known in the art and include, but are not limited to, the maize In2-2 promoter, which is activated by benzene sulfonamide herbicide safeners; the maize GST promoter, which is activated by hydrophobic electrophilic compounds that are used as pre-emergent herbicides...
Such genes may encode either a selectable or screenable marker, depending on whether the marker confers a trait which one can “select” for by chemical means, i.e., through the use of a selective agent (e.g., a herbicide, antibiotic, or the like), or whether it is simply a trait ...
The polynucleotides of the present disclosure can also be stacked with traits desirable for disease or herbicide resistance (e.g., fumonisin detoxification genes (U.S. Pat. No. 5,792,931); avirulence and disease resistance genes (Jones et al. (1994) Science 266:789; Martin et al. (1993...
