Abstract: FLOWERING LOCUS C (FLC) is an important repressor of plant flowering. It mainly represses flowering by binding to the promoters of two downstream key floral promoting genes, FLOWERING LOCUS T (FT) and SUPPRESSOR OF OVEREXPRESSION OF CO 1 (SOC1). It also regulates flowering time by binding to other regulatory genes. While the detailed molecular mechanisms of FLC in the regulation of flowering still need to be deeply investigated. This review summarizes the new research progresses of FLC in recent years in the 8 genetic pathways of flowering regulation, and give an outlook for the future study in this field.

Key words: FLC, flowering regulation pathway, flowering time
