Genbank accession number
- Key message
- Here we show that osfkf1 mutants flower late under SD, LD, and natural LD conditions
- Transcriptional analysis revealed that OsFKF1 up-regulates expression of the floral activator Ehd2 and down-regulates expression of the floral repressor Ghd7; these regulators up- and down-regulate Ehd1 expression, respectively
- In contrast to the LD-specific floral activator Arabidopsis FKF1, OsFKF1 likely acts as an autonomous floral activator because it promotes flowering independent of photoperiod, probably via its distinct roles in controlling expression of rice-specific genes including Ehd2, Ghd7, and Ehd1

- FKF1~OsFKF1, OsDof12~OsCDF1, Rice FLAVIN-BINDING, KELCH REPEAT, F-BOX 1 OsFKF1 promotes flowering independent of photoperiod., Like Arabidopsis FKF1, which interacts with GI and CDF1, OsFKF1 also interacts with OsGI and OsCDF1 (also termed OsDOF12)
- FKF1~OsFKF1, OsGI, Rice FLAVIN-BINDING, KELCH REPEAT, F-BOX 1 OsFKF1 promotes flowering independent of photoperiod., Like Arabidopsis FKF1, which interacts with GI and CDF1, OsFKF1 also interacts with OsGI and OsCDF1 (also termed OsDOF12)
- FKF1~OsFKF1, OsHUB2~FRRP1, OsHUB2 inhibits function of OsTrx1 in heading date in rice., The expression of Hd3a, RFT1, and Ehd1 was induced and the transcript levels of Hd1, Ghd7, OsCCA1, OsGI, OsFKF1, and OsTOC1 were reduced under long-day conditions, whereas RFT1 and Ehd1 expression was induced in oshub2 mutants under short-day conditions
- FKF1~OsFKF1, OsFBO10, OsCRY2 and OsFBO10 co-regulate photomorphogenesis and photoperiodic flowering in indica rice., Novel interactions were confirmed between OsCRY2 and members of ZEITLUPE family of blue/ultraviolet-A light photoreceptors, encoded by OsFBO8, OsFBO9 and OsFBO10 which are orthologous to ZEITLUPE (ZTL), LOV KELCH PROTEIN2 (LKP2) and FLAVIN BINDING, KELCH REPEAT F-BOX1 (FKF1), respectively, of Arabidopsis thaliana
- FKF1~OsFKF1, OsFBO10, OsCRY2 and OsFBO10 co-regulate photomorphogenesis and photoperiodic flowering in indica rice., Since FKF1 is known to play a role in regulating photoperiodic flowering, OsFBO10 was chosen for further studies
