Abstract
The present invention relates generally to the field of molecular biology and concerns a method for enhancing various yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a TCP1 transcription factor. The present invention also concerns plants having modulated expression of a nucleic acid encoding a TCP1 polypeptide, which plants have enhanced yield-related traits relative to corresponding wild type plants or other control plants. The invention also provides constructs useful in the methods of the invention.
Claims24
A method for enhancing yield-related traits in a plant relative to a control plant, said method comprises modulating expression of a nucleic acid encoding a TCP 1 polypeptide in a plant, and selecting a plant having enhanced yield-related traits on the basis of said plant showing enhanced yield-related traits relative to a control plant, wherein said TCP 1 polypeptide comprises an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
- 2.
A construct comprising:
- (i) a nucleic acid sequence encoding a TCP 1 polypeptide;
- (ii) one or more control sequences capable of driving expression of the nucleic acid sequence of (i);
- and optionally
- (iii) a transcription termination sequence,
- wherein said TCP 1 polypeptide comprises an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
- 2.
A method for the production of a transgenic plant having increased seed yield relative to a control plant, comprising:
- introducing and expressing in a plant or plant cell a nucleic acid encoding a TCP 1 polypeptide;
- (ii) cultivating the plant or plant cell under conditions promoting plant growth and development;
- and
- (iii) selecting a plant having increased seed yield on the basis of said plant showing increased seed yield relative to a control plant,
- wherein said TCP1 polypeptide comprises an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
- 2.
A transgenic plant having increased yield or increased seed yield relative to a control plant resulting from increased expression of a nucleic acid encoding a TCP1 polypeptide, or a transgenic plant cell or progeny derived from said transgenic plant, wherein said transgenic plant cell or progeny comprises the nucleic acid encoding the TCP1 polypeptide, and wherein said TCP 1 polypeptide comprises an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
- 2.
