Gene Symbol
- Os06g0142600 <=> Hd17, EF7, Ef7, OsELF3-1, OsELF3
Function
- Heading date 17 (Hd17) is a gene that encodes a homolog of Arabidopsis EARLY FLOWERING 3 (ELF3),which plays important roles in maintaining circadian rhythms, and that the QTL lies within the pathway responsible for rice’s photoperiodic flowering through the modulation of the transcription level of a flowering repressor, Grain number, plant height and heading date7(Ghd7).
- 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[1].
Expression
Os06g1042600 is the Hd17 gene, and that the SNP in Os06g0142600 caused the flowering time difference between ‘Nipponbare’ and NIL-Hd17. Nevertheless, the nucleotide change in Hd17 does not appear to affect its transcription level.The nucleotide change in Hd17 did not seem to affect Hd1 expression; however, its effect on flowering time disappeared in a background with a defective Hd1 allele[1].Hd17 promotes flowering under long and short day conditions by negatively regulating the flowering repressor Ghd7, and consequently upregulating levels of Ehd1 and FT-like gene expression[1].
