The present invention relates generally to the field of molecular biology and concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a yield increasing polypeptide selected from the group consisting of:phosphoenolpyruvate carboxylase (PEPC),Class III U-Box protein andPQQC protein. The present invention also concerns plants having modulated expression of a nucleic acid encoding yield increasing polypeptide selected from the group consisting of:phosphoenolpyruvate carboxylase (PEPC),Class III U-Box protein andPQQC protein, which plants have enhanced yield-related traits relative to corresponding wild type plants or other control plants. The invention also provides constructs useful in the methods of the invention.
