<p>A method of transforming a C4 plant; and a method of overexpressing a foreign gene in a C4 plant. More specifically, a method of constructing a C4 plant showing an excellent photosynthesis ability even at a low temperature by overexpressing an enzyme constituting the photosynthesis pathway of the C4 plant. A C4 plant is transformed by using an expression cassette containing a promoter, a C4 plant genomic gene encoding an enzyme constituting the photosynthesis pathway under the regulation by the promoter and a terminator. It is preferable that the C4 plant genomic gene encoding an enzyme constituting the photosynthesis pathway is a C4 plant genome-origin PPDK gene or its variant. The above method is particularly useful in elevating the productivity of a C4 plant carrying PPDK (among all, elevating the productivity of corn under cold conditions).</p> |
