Abstract:
1. A plant transformed by introducing a polynucleotide encoding a plant-derived γ-glutamylcysteine synthetase, the polynucleotide producing a translated product having no chloroplast targeting signal peptide, the plant being further increased in biomass quantity per unit area or seed yield per unit area in comparison with a parent plant thereof by being cultivated at a planting density higher than that which allows increases in the biomass quantity per unit area and in the seed yield per unit area wherein the polynucleotide encoding the γ-glutamylcysteine synthetase is selected from the group consisting of the following (a) to (d): (a) a polynucleotide encoding a polypeptide having the amino-acid sequence comprising SEQ ID NO: 3; (b) a polynucleotide encoding a polypeptide having an amino-acid sequence in which not more than 10 amino acids of which are deleted, substituted, or added from/in/to the amino-acid sequence comprising SEQ ID NO: 3; (c) a polynucleotide having the base sequence comprising SEQ ID NO: 4; and (d) a polynucleotide that hybridizes, under stringent conditions, with the polynucleotide having the base sequence comprising SEQ ID NO: 4.
