Divergence of the genetic contribution of FRIGIDA homologues in regulating the flowering time in Brassica rapa ssp. rapa

•Two BrrFRI homologues from turnip were identified which showed differences in the coiled-coil domains.•BrrFRIa protein effectively activated the promoter of BrrFLC2.•BrrFRIa had stronger effects on the repression of flowering time than BrrFRIb in Arabidopsis.•BrrFRIa was significantly enriched in t...

Description
Summary:•Two BrrFRI homologues from turnip were identified which showed differences in the coiled-coil domains.•BrrFRIa protein effectively activated the promoter of BrrFLC2.•BrrFRIa had stronger effects on the repression of flowering time than BrrFRIb in Arabidopsis.•BrrFRIa was significantly enriched in the region around the TSS of AtFLC chromatin.•BrrFRIa-OE lines needed a longer period of vernalization to flower than the BrrFRIb-OE lines.
