    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.
