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.

Abstract:
An herbicidal composition containing (a) a pyridine or pyrimidine carboxylic acid component and (b) a second cereal or rice herbicide component provides synergistic control of selected weeds.
Abstract:
The subject invention provides novel plants that are not only resistant to 2,4-D, but also to a pyridyloxyacetate herbicide. 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-13 (AryloxyAlkanoate Dioxygenase). This highly novel discovery is the basis of significant herbicide tolerant crop trait and selectable marker opportunities.
Abstract:
Provided herein are herbicidal compositions comprising a mixture comprising (a) the choline salt of 2,4-dichlorophenoxyacetic acid (2,4-D-choline), (b) a salt of N-(phosphonomethyl)glycine (glyphosate), and (c) a salt of 2-amino-4-(hydroxymethylphosphinyl)-butanoic acid (glufosinate). The compositions provide synergistic weed control of undesirable vegetation and improved crop tolerance in 2,4-D-, glyphosate- and glufosinate-tolerant soybeans, corn, or cotton The compositions also provide synergistic weed control of undesirable vegetation in areas including, but not limited to, non-crop, perennial crop, fruiting crop, and plantation crop areas.

Abstract:
A system for high temporal and high spatial resolution monitoring of a field of plants is disclosed. Illustratively, the system includes a plurality of ground based reference objects, a balloon adapted to be positioned above the field of plants, and a balloon positioning system coupled to the balloon and configured to position the balloon relative to the field of plants. An imaging system is supported by the balloon and includes a location system, at least one camera, and at least one gimbal configured to orient the at least one camera. The imaging system captures at least one image of the field of plants including the plurality of ground based reference objects in the at least one image.

Abstract:
The present disclosure relates to the use of a grass-active herbicide postemergently applied to AAD1-transformed turfgrasses to selectively control grass weeds in a turf grass crop. Also described is the use of AAD1 as a selectable marker in the production of transgenic turfgrass.
