The present invention relates generally to the field of molecular biology and concerns a method for enhancing various yield related-traits by modulating expression in a plant of a nucleic acid encoding a YEF1(Yield Enhancing Factor 1). The present invention also concerns plants having modulated expression of a nucleic acid encoding a YEF1, 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.
