function
OsCOL4, a member of the CONSTANS-like (COL) family in rice.OsCOL4 is a constitutive repressorfunctioning upstream of Ehd1 and functions independently from previously reported flowering pathways. In osphyB mutants, OsCOL4 expression was decreased and osphyB oscol4 double mutants flowered at the same time as the osphyB single mutants,indicating OsCOL4 functions downstream of OsphyB.[1]
Expression
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
Evolution
Plants recognize environmental factors to determine flowering time. CONSTANS (CO) plays a central role in the photoperiod flowering pathway of Arabidopsis, and CO protein stability is modulated by photoreceptors. In the former, GIGANTEA (GI) activates CONSTANS (CO), which promotes Flowering Locus T (FT) expression (Fowler et al.,1999; Park et al., 1999; Samach et al., 2000; Yanovsky and Kay, 2002). The CO gene is a member of a B-box transcription factor family which contains a CCT (CO, CO-like, and TOC1) domain at the C-terminal end (Putterill et al., 1995; Borden, 1998; Robson et al., 2001).In rice, Hd1, an ortholog of CO, acts as a flowering promoter, and phytochromes repress Hd1 expression.The rice genome contains 16 OsCOL genes (Griffiths et al.,2003). Among them, Hd1 was identified first via QTL analyses (Yano et al., 2000). Two groups of rice COL proteins differ from those in Arabidopsis (Griffiths et al., 2003).
