-OsCOL4 null mutants ﬂowered early under short or long days. In contrast, OsCOL4 activation-tagging mutants (OsCOL4-D) ﬂowered late in either environment. Transcripts of Ehd1, Hd3a, and RFT1 were increased in the oscol4 mutants, but reduced in the OsCOL4-D mutants. By comparison, levels of Hd1, OsID1, OsMADS50, OsMADS51, and OsMADS56 transcripts were not signiﬁcantly changed in oscol4 or OsCOL4-D.In osphyB mutants, OsCOL4 expression was decreased and osphyB oscol4 double mutants ﬂowered at the same time as the osphyB single mutants<ref name="ref1" />
