A detailed linkage analysis of the Ehd1 region was performed with a large segregating population, essential for map-based cloning. As a result, the Ehd1 gene promoting rice heading (flowering) was successfully isolated. Rice heading time was also found to be altered upon introduction of this gene. Based on these facts, the newly isolated and identified Ehd1 gene is expected to be useful in promoting plant flowering.

Ehd1 gene promoting plant flowering, and utilization thereof

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.
