COMPOSITIONS AND METHODS OF USE OF MITOGEN-ACTIVATED PROTEIN KINASE KINASE KINASE

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.
