Provided is a method for enhancing yield-related traits in plants by modulating expression of a nucleic acid encoding a PtMYB12L polypeptide in a plant. Also provided are plants having modulated expression of a nucleic acid encoding a PtMYB12L polypeptide, which plants have enhanced yield-related traits compared with control plants. Also provided are PtMYB12L-encoding nucleic acids, and constructs comprising the same, useful in enhancing yield-related traits in plants.
