Description

Hyeryung Yoon and four co-authors uncover how rice plants use day length to time their flowering, in this 2025 study. Rice flowers early under short days and holds back under long ones. Genes that block flowering in long days were known, but how the plant disposes of those blockers when days shorten was not.

The team shows that a protein called OsFKF1 grabs a flowering blocker, OsPRR37, and sends it for destruction. With the blocker cleared, a flowering switch gene turns on and the plant heads early under short days. A second protein, Hd1, partners with the blocker to hold flowering back in long days. Tests with double mutants back the scheme. The findings fill in the daily clockwork behind a trait that decides harvest timing.
