Plants having enhanced yield-related traits and a method for making the same

摘要

The present invention relates generally to the field of molecular biology and concerns a method for enhancing yield-related traits and/or improving various plant growth characteristics by modulating expression in a plant of a nucleic acid encoding a GRP (Growth Regulating Protein). The GRP is selected from a LOB-domain comprising protein (LOB: Lateral Organ Boundaries), herein abbreviated as LBD polypeptide, a JMJC (JUMONJI-C) polypeptide, a CKI 10 (Casein Kinase I) polypeptide, a bHLH11-like (basic Helix-Loop-Helix 11) protein, a plant homeodomain finger-homeodomain (PHDf-HD) polypeptide, an ASR (abscisic acid-, stress-, and ripening-induced) polypeptide and/or a Squamosa promoter binding protein-like (SPL11) transcription factor polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding a GRP, which plants have improved growth characteristics relative to corresponding wild type plants or other control plants. The invention also provides novel GRP nucleic acids and GRP polypeptides as well as constructs useful in the methods of the invention.
