It is intended to provide a plant having an elevated glutamate:gluoxylate aminotransferase (GGT) activity; a method of constructing the same; and seed s of this plant. It is also intended to provide a plant having an elevated ami no acid content, in particular, elevated content(s) of one or more amino acids selected from the group consisting of serine, arginine, glutamine and asparagine, compared with a wild type of the same plant grown under the same conditions; a method of constructing the same; and seeds of this plant. Namely, a plant having an elevated GGT activity is constructed by mutagenesi s, transfer of a nucleic acid molecule, etc. A genetic construct capable of enhancing the expression of a GGT gene, in particular, a genetic construct capable of enhancing the expression of a GGT gene and/or a genetic construct capable of increasing the expression dose of a gene having endogenous GGT activity are transferred into a plant.
