The present invention relates generally to the field of molecular biology and concerns a method for enhancing various economically important yield-related traits in plants. More specifically, the present invention concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a basic/helix-loop-helix (bHLH) transcription factor. The present invention also concerns plants having modulated expression of a nucleic acid encoding a bHLH transcription factor, which plants have enhanced yield-related traits relative to control plants. The invention also provides constructs useful in the methods of the invention.
