摘要:
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.
摘要:
The present invention provides compositions and methods for regulating expression of nucleotide sequences in a plant. Compositions comprise novel nucleic acid sequences encoding a transcription factor 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.
