Dear Editor,Recently,it was reported that the florigenic FT protein bound to a 3 egion of the potent floral repressor FLC (FLOWERING LOCUS C) to activate the expression of long noncoding antisense RNAs known as COOLAIR and consequently repress FLC expression to control flowering time and seed dormancy in Arabidopsis (Chen and Penfield,2018).Here,we show that FT represses FLC expression through a 5promoter region,but not COOLAIR.
