The present invention relates to a novel plant expression construct. More specifically the present invention provides a DNA construct comprising 5′ regulatory sequences for modulating the expression of operably linked genes in plants.

Plant expression constructs

The invention provides cropping systems for managing weeds in crop environments. The cropping systems comprise, in one embodiment, transgenic plants that display tolerance to an auxin-like herbicide such as dicamba. Method for minimizing the development of herbicide resistant weeds are also provided.

Cropping systems for managing weeds

The invention provides for identification and use of certain chloroplast transit peptides for efficient processing and localization of dicamba monooxygenase (DMO) enzyme in transgenic plants. Methods for producing dicamba tolerant plants, methods for controlling weed growth, and methods for producing food, feed, and other products are also provided, as well as seed that confers tolerance to dicamba when it is applied pre- or post-emergence.

Chloroplast transit peptides for efficient targeting of DMO and uses thereof

Genes encoding Class II EPSPS enzymes are disclosed. The genes are useful in producing transformed bacteria and plants which are tolerant to glyphosate herbicide. Class II EPSPS genes share little homology with known, Class I EPSPS genes, and do not hybridize to probes from Class I EPSPS's. The Class II EPSPS enzymes are characterized by being more kinetically efficient than Class I EPSPS's in the presence of glyphosate. Plants transformed with Class II EPSPS genes are also disclosed as well as a method for selectively controlling weeds in a planted transgenic crop field.

Glyphosate-tolerant 5-enolpyruvylshikimate-3-phosphate synthases

The present invention provides methods and compositions for improving plant health. In particular, application of dicamba or another substrate of DMO, or metabolites thereof including DCSA, to a plant confers tolerance to, or defense against, abiotic or biotic stresses such as oxidative stress including herbicide application, and plant disease, and enhances crop yield. Such application may be in combination with the application of another herbicide such as glyphosate.
