+* In rice, '''''phyA''''' suppresses flowering under LD conditions, and the effect does not depend on light quality.

Because daylengths during this cultivation were >13 h, our natural daylength condition was considered equivalent to LD conditions. The phyA mutation delays, the phyB accelerates, and the phyC has no effect on the flowering, but the double mutations caused different responses.
