Maize ethylene signaling genes and modulation of same for improved stress tolerance in plants

The present invention provides polynucleotides and related polypeptides of the ZmERECTA gene family. The invention provides nucleic acid sequences for the Zm ERECTA genes. ZmERECTA is responsible for controlling plant growth, organ size and yield in crop plants.

Maize ERECTA genes for improving plant growth, transpiration, efficiency and drought tolerance in crop plants

The present invention provides compositions and methods for regulating expression of nucleotide sequences in a plant. Compositions comprise novel nucleic acid sequences encoding a transcriptional activator involved in modulating gene expression in response to abiotic stress such as cold or drought. Methods for expressing the nucleic acid sequence in a plant and improving cold and/or drought tolerance of plants are also provided.

NAC transcriptional activators involved in abiotic stress tolerance

The invention provides isolated maize EIN3, ERF3, EBF1, EBF2, EIN5 nucleic acids which are associated with ethylene signaling in plants and their encoded proteins. The present invention provides methods and compositions relating to altering ethylene sensitivity in plants. The invention further provides recombinant expression cassettes, host cells, transgenic plants and antibody compositions.

Methods and compositions for modulating plant response, development and yield under varying environmental conditions are provided. Methods employing MAPKKK are provided. The MAPKKK sequences are used in a variety of methods including modulating root development, modulating leaf and/or shoot development, modulating tolerance under abiotic stress and modulating yield. Transformed plants, plant cell, tissues, seed and expression vectors are also provided.

Compositions and methods of use of mitogen-activated protein kinase kinase kinase

Compositions and methods for regulating expression of heterologous polynucleotide sequences in a plant are provided. Compositions are novel nucleotide sequences comprising an isolated stress-induced promoter natively linked to the maize CBF1 or CBF2 coding region. A method for expressing a heterologous polynucleotide sequence in a plant using the regulatory sequences disclosed herein is provided. The method comprises transforming a plant cell to comprise a heterologous polynucleotide sequence operably linked to one or more of the regulatory sequences of the present invention and regenerating a stably transformed plant from the transformed plant cell.

Regulatory elements associated with CBF transcription factors of maize

The present invention provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions are novel nucleotide sequences for a stress-induced promoter endogenously associated with the rye CBF31 coding region. A method for expressing a heterologous nucleotide sequence in a plant or plant cell using the regulatory sequences disclosed herein is provided. The method comprises transforming a plant cell to comprise a heterologous nucleotide sequence operably linked to a regulatory sequence of the present invention and optionally regenerating a stably transformed plant from the transformed plant cell.
