Functional Descriptions:

  • Moreover, OsELF3-1 suppresses a flowering repressor grain number, plant height and heading date 7 (Ghd7) to indirectly accelerate flowering under long-day (LD) conditions.
  • Identification of a novel gene Ef7 conferring an extremely long basic vegetative growth phase in rice.
  • In addition, OsELF3-1 is involved in blue light signaling by activating early heading date 1 (Ehd1) expression to promote rice flowering under short-day (SD) conditions.
  • We previously identified a quantitative trait locus, Heading date 17 (Hd17), that is associated with a difference in flowering time between Japanese rice (Oryza sativa L.
  • Our results demonstrate that natural variation in Hd17 may change the transcription level of a flowering repressor, Grain number, plant height and heading date 7 (Ghd7), suggesting that Hd17 is part of rice’s photoperiodic flowering pathway.
  • Expression analyses of flowering time-related genes demonstrated that Ef7 negatively regulates the expression of Ghd7, which is a repressor of the photoperiodic control of rice flowering, and consequently up-regulates the expression of the downstream Ehd1 and FT-like genes under both SD and LD conditions.
  • Taken together, our results indicate OsELF3-1 is essential for circadian regulation and photoperiodic flowering in rice.
  • OsELF3-1, an ortholog of Arabidopsis early flowering 3, regulates rice circadian rhythm and photoperiodic flowering.
  • Natural variation in Hd17, a homolog of Arabidopsis ELF3 that is involved in rice photoperiodic flowering.
  • Thus, our results show that Ef7 functions as a floral promoter by repressing Ghd7 expression under both SD and LD conditions.
  • Ef7 encodes an ELF3-like protein and promotes rice flowering by negatively regulating the floral repressor gene Ghd7 under both short- and long-day conditions.
  • In this study, we identified and characterized the Ef7 gene, one of the rice orthologs of Arabidopsis EARLY FLOWERING 3 (ELF3).
  • The Ef7 mutant HS276, which was induced by gamma-irradiation of the japonica rice cultivar ‘Gimbozu’, flowers late under both SD and LD conditions.
  • Genetic analyses with a non-functional Ghd7 allele provided further evidence that the delayed flowering of Ef7 is mediated through the Ghd7 pathway.
  • HAF1 Modulates Circadian Accumulation of OsELF3 Controlling Heading Date Under Long-day Conditions in Rice.
  • An amino acid variation (L558S) within the interaction domain of OsELF3 with HAF1 greatly contributes to the variation in heading date among japonica rice accessions.
  • Taken together, our findings suggest that HAF1 precisely modulates the diurnal rhythm of OsELF3 accumulation to ensure the appropriate heading date in rice.
  • Previous studies have suggested that OsELF3-1 has a predominant role in controlling rice photoperiodic flowering, while also contributing to the transcriptional regulation of rice floral regulators expressed in the morning.
  • OsELF3-1 contributes to the translocation of OsLUX to the nucleus, and a compromised flowering phenotype results upon mutation of any component of the OsEC complex.
