Methods for enhancing various economically important yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a LEJ1 (Loss of timing of ET and JA biosynthesisI) polypeptide, ExbB polypeptide, NMPRT (nicotinamide phosphoribosyltransferase) polypeptide, AP2-26-like polypeptide or HD8-like polypeptide are provided. Plants produced by the methods are also provided, which have enhanced yield-related traits relative to corresponding wild type plants or other control plants. Constructs comprising a nucleic acid encoding a LEJ1, ExbB, NMPRT, AP2-26-like or HD8-like polypeptide and uses thereof are provided.
