A rice photosensitivity gene Hd1 is successfully isolated by linkage analysis. It is found out that the photosensitivity of a plant can be modified by transferring this gene or controlling the expression thereof. It is further found out that the photosensitivity of a plant can be evaluated by examining the presence/absence of this functional gene.

A blast disease-resistance gene (Pi-b), a functionally equivalent gene thereof and proteins encoded by the genes are provided. The gene is useful for creating a plant resistant to the blast disease and can confer a resistance to a broad range of the rice blast fungi on plants. Therefore, it is useful for controlling the disease and increasing crop yields.
