Molecular control of seasonal flowering in rice, arabidopsis and temperate ce…

† Background: Rice (Oryza sativa) and Arabidopsis thaliana have been widely used as model systems to understand howplants controlflowering time in response to photoperiod and cold exposure. Extensive research has resulted in the isolation of several regulatory genes involved in flowering and for them to be organized into a molecular network responsive to environmental cues. When plants are ex…
