Schematic model illustrating a role of the EC in regulating flowering time in maize. ZmELF3.1/3.2 bridge ZmELF4.1/4.2 and ZmLUX1/2 to form ECs, and then the EC directly represses the expression of a set of flowering repressor genes: ZmCCT9, ZmCCT10, ZmCOL3, ZmPRR37a, and ZmPRR73, thereby relieving their suppression on expression of three maize florigen genes (ZCN8, ZCN7, and ZCN12), to promote flowering. Insertion of an LTR/Gypsy and a NonLTR/L1 retrotransposon upstream of ZmELF3.1 enhances the expression of ZmELF3.1, thus promoting flowering. Arrow: activation; Bar: repression.
