Abstract
The present invention relates generally to the field of molecular biology and concerns a method for enhancing various economically important yield-related traits in plants. More specifically, the present invention concerns a method for enhancing yield-related traits in plants grown under nutrient deficient conditions, comprising modulating expression in a plant of a nucleic acid encoding a GGAT polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding a GGAT, which plants have enhanced yield-related traits relative to control plants.
Claims14
A method for increasing biomass and seed yield in a plant grown under nitrogen deficient conditions, said method comprising the steps of:
- (a) transforming plant cells with a polynucleotide comprising a nucleic acid sequence encoding a Glutamate:Glyoxylate aminotransferase (GGAT) polypeptide having an amino acid sequence that is at least 98% identical to the amino acid sequence set forth in SEQ ID NO:
- 2, and wherein the nucleic acid sequence is operably linked to a promoter;
- (b) regenerating transgenic plants from said transformed plant cells;
- and
- (c) selecting a transformed plant from said transgenic plants which exhibits increase in biomass and seed yield as compared to an untransformed plant of the same species grown under said nitrogen deficient conditions, and wherein said increase in biomass and seed yield is due to the expression of said GGAT polypeptide in said selected transformed plant.
A method for producing a plant having increased biomass and seed yield under nitrogen deficient conditions, said method comprising the steps of:
- (a) transforming plant cells with a genetic construct comprising a nucleic acid sequence encoding a Glutamate:Glyoxylate aminotransferase (GGAT) polypeptide having an amino acid sequence that is at least 98% identical to the amino acid sequence set forth in SEQ ID NO:
- 2, and wherein the nucleic acid sequence is operably linked to a promoter;
- (b) regenerating transgenic plants from said transformed plant cells;
- and
- (c) selecting a transformed plant from said transgenic plants which exhibits increase in biomass and seed yield as compared to an untransformed plant of the same species grown under said nitrogen deficient conditions, and wherein said increase in biomass and seed yield is due to the expression of said GGAT polypeptide in said selected transformed plant.
