Abstract: Flowering transformation from vegetative growth to reproductive growth is the key link for plants to adapt to the external environments and ensure their reproduction, which is mainly influenced by internal regulation and external environmental factors. Photoperiod is an important factor that affects plant flowering, and the researches on molecular mechanism of photoperiod-regulation flowering were relatively in-depth. In this paper, the molecular mechanism underlying photoperiod-regulation flowering in Arabidopsis, rice, sorghum and foxtail millet was summarized combined with the latest research achievements in recent years. Furthermore, a gene family containing CCT motif that played a key role in photoperiod-regulation flowering pathway was introduced, and the functions of different members of this family in each crop were generalized, to provide theoretical reference for further study on the function of CCT motif-containing gene family and molecular breeding of traits related to photoperiod-regulated flowering.

Key words: photoperiod, flowering, molecular mechanism, CCT gene family
