The present invention relates generally to the field of molecular biology and concerns a method for enhancing various economically important yield-related traits in plants. More specifically, the present invention concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a HAB1 (Hypersensitive to ABA1) polypeptide or a KELP polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding a HAB1 polypeptide or a KELP polypeptide, which have enhanced yield-related traits relative to control plants. The invention also provides hitherto unknown HAB1-encoding nucleic acids, and constructs comprising HAB1 or KELP-encoding nucleic acids, useful in performing the methods of the invention.
