PLANTS HAVING ENCHANCED YIELD RELATED TRAITS AND METHOD FOR MAKING THE SAME

摘要

A method for enhancing yield related traits in plants by modulating expression in a plant of a nucleic acid up regulated upon overexpression of a NAC1 or NAC5 encoding gene referred to herein as a NUG or NAC up regulated gene is provided. Plants having modulated expression of a NUG which plants have enhanced yield related traits relative to corresponding wild type plants or other control plants are also provided. A method for conferring abiotic stress tolerance in plants comprising modulating expression of a nucleic acid encoding a NAC1 or NAC5 polypeptide in plants grown under abiotic stress conditions is also provided. Plants expressing a nucleic acid encoding a NAC1 or NAC5 polypeptide aside from having increased abiotic stress tolerance have enhanced yield related traits and/or modified root architecture compared to corresponding wild type plants. Constructs useful in the methods and plants produced by the methods are also provided.
