A method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a FB013 (F-box and other domain containing protein) polypeptide is provided. Plants having modulated expression of a nucleic acid encoding a FB013 polypeptide, which plants have enhanced yield-related traits relative to control plants, hitherto unknown FB013-encoding nucleic acids, and constructs comprising the same, which are useful in performing the methods, are also provided.
