Abstract:

In this review, we focus on the recent progress made in CO/FT regulon and its role in adjusting plant flowering. Flowering is a key process for plant to transfer from vegetative to reproductive development. Photoperiod and temperature play critical roles in controlling flowering time. In Arabidopsis and rice, CONSTANS (CO) and its target gene FLOWERING LOCUS T（FT） play a key role in day-length measurement. The CO/FT regulon has played an important role in photoperiod dependent flowering. At present, CO and FT orthologs have been identified from different plant species, and their roles in plant flowering time control have been studied intensively.

Key words: CO/FT regulon, flowering time, photoperiod, CONSTANS, FLOWERING LOCUS T
