摘要： Methods and compositions for modulating plant development are provided. Polynucleotide sequences encoding ZmSNAC polypeptides are provided, as are the amino acid sequences of the encoded polypeptides. The sequences can be used in a variety of methods including modulating root development, modulating floral development, modulating leaf and/or shoot development, modulating senescence, modulating seed size and/or weight, and modulating tolerance of plants to abiotic stress. Transformed plants, plant cells, tissues, and seed are also provided. A stress-inducible ZmSNAC1 promoter is also provided.

摘要： Compositions and methods for suppressing the shade-avoidance response of plants and improving plant yield are provided. Compositions of the invention include an early flowering 3 (ELF3) maize gene, the promoter for this gene, an Arabidopsis basic helix-loop-helix transcription factor (bHLH-041), and fragments and variants thereof. The ELF3 promoter sequence is useful for driving expression of polynucleotides of interest in a plant. The ELF3 and bHLH-041 sequences of the invention, or variants and fragments thereof, are provided in expression cassettes for use in manipulating expression of the ELF3 and bHLH-041 genes. By increasing expression of ELF3 and/or suppressing expression of bHLH-041, the methods of the invention provide for altered response of a plant to light quality and suppression of the high-density-invoked survival mode of development. The invention thus provides methods for growing crop plants at high population densities for yield enhancement. Transformed plants having the altered shade-avoidance phenotype of the invention, and seeds of said plants, are also provided.
