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

This invention relates to isolated polynucleotides encoding WUS polypeptides. The invention further provides isolated WUS polypeptides. The invention also provides methods of using the polynucleotides to modulate the level of WUS, improve transformation efficiency, to stimulate plant cell growth, including stem cells, to stimulate organogenesis, to stimulate somatic embryogenesis, to induce apomixis, and to provide a positive selection for cells comprising the polynucleotide. The invention also relates to cells, plants and seeds comprising the polynucleotides of the invention or produced by the methods of the invention.

Methods and compositions for modulating development and/or developmental pathways are provided. The compositions of the present invention comprise nucleic acid and amino acid sequences. Particularly, the nucleotide sequence (SEQ ID NO:1, 3, 4 or 7) and amino acid sequence (SEQ ID NO:2 or 8) for a maize CLAVATA3-like (CLV3-like) polypeptide are provided. Methods are provided for the expression of the CLV3-like sequences in a host plant or plant cell to modulate plant development and/or developmental pathways. The methods of the invention find use in controlling or modulating cell division, differentiation and development. In particular, the sequences of the present invention find use in modulating meristem development. Transformed plants, plant cells, tissues, and seed are also provided.
