Annotated Information
Gene Symbol
- Os10g0463400 <=> Ehd1,OsEhd1
Function
- The rice Early heading date 1 (Ehd1) gene, which confers SD promotion of flowering in the absence of a functional allele of Hd1, encodes a B-type response regulator that might not have an ortholog in the Arabidopsis genome.
- Ehd1 mRNA was induced by 1-wk SD treatment, and Ehd1 may promote flowering by inducing FT-like gene expression only under SD conditions.
- Microarray analysis further revealed a few MADS box genes downstream of Ehd1.
Expression
- In the T65 background, Ehd1-gla exhibited a diurnal expression pattern under SD (9L:15D) condition and a rapid damping of circadian oscillation in subsequent continuous darkness.
