| 摘要 |
The present invention concerns a method for improving plant growth characteristics by modulating expression of a nucleic acid encoding a PRE-like (Paclobutrazol REsistance) polypeptide. The invention further concerns a method for enhancing yield-related traits by modulating expression of a nucleic acid encoding an SCE1 (SUMO Conjugating Enzyme 1), a YEF1 (Yield Enhancing Factor 1), or a subgroup III glutaredoxin (Grx). The invention also concerns a method for altering the ratio of roots to shoots in plants by modulating expression of a nucleic acid encoding a Sister of FT protein or a homologue thereof. Plants having modulated expression of a PRE-like polypeptide, an SCE1, a YEF1, a subgroup III Grx, or Sister of FT protein and improved growth characteristics, enhanced yield-related traits, or altered root to shoot ratio relative to a corresponding wild type or control plant are also provided. Further provided are constructs useful in the methods of the invention. |
