Significance Plants know the exact time of flowering by sensing the photoperiod. Flowering time is an important agronomic trait in crops. In order to ensure that crops maintain high yields in different latitudes, cultivars need to accurately adjust the flowering time of plants according to local photoperiod and environmental conditions. In many plants, phytochromes have been found to be involved in photoperiodic flowering, but the molecular mechanisms of how they control photoperiod flowering are not fully understood. Through a series of biochemical, molecular, and genetic analyses of soybean phytochrome A, we reveal a photoperiod flowering mechanism in plants by which the phytochrome A regulates LUX and E1 activity.
