A method for enhancing various economically important yield-related traits in plants by modulating expression of a nucleic acid encoding a flavodoxin polypeptide in plants in a specific way. Provided are plants having the expression of a nucleic acid encoding a flavodoxin polypeptide modulated by a particular type of promoter, which plants have enhanced yield-related traits compared with control plants. Hitherto unknown constructs, which are useful in performing the methods of the invention, are also provided.
