The present invention relates generally to the field of molecular biology and concerns a method for enhancing various plant yield-related traits by modulating expression in a plant of a nucleic acid encoding a RHL1 (Root Hairless 1). The present invention also concerns plants having modulated expression of a nucleic acid encoding a RHL1, which plants have enhanced various plant yield-related relative to corresponding wild type plants or other control plants. The invention also provides constructs useful in the methods of the invention.
