The present invention relates generally to the field of molecular biology and concerns a method for altering the ratio of roots to shoots in plants by modulating expression in a plant of a nucleic acid encoding a Sister of FT protein or a homologue thereof. The present invention also concerns plants having modulated expression of a nucleic acid encoding a Sister of FT protein or a homologue thereof, which plants have altered root to shoot ratio relative to corresponding wild type plants or other control plants. The invention also provides constructs useful in the methods of the invention.
