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.
