Gene Details:

• MSU gene ID: LOC_Os08g01420
• RAPdb gene ID: Os08g0105000
• Gene Symbol: Ehd3
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Transcript levels of OsGI, phytochrome genes, and Early heading date3 (Ehd3), which function upstream of Ghd7, were unchanged in the mutant.
• We report here that an early heading date 3 (Ehd3) mutant flowered later than wild-type plants, particularly under LD conditions, regardless of the Hd1-deficient background.
• To identify the role of Ehd3 within the gene regulatory network for rice flowering, we compared the transcript levels of genes related to rice flowering in wild-type plants and Ehd3 mutants.
• Furthermore, Ehd3 ghd7 plants flowered earlier and show higher Ehd1 transcript levels than Ehd3 ghd7 plants, suggesting a Ghd7-independent role of Ehd3 in the upregulation of Ehd1.
• Our results demonstrate that the PHD-finger gene Ehd3 acts as a promoter in the unique genetic pathway responsible for photoperiodic flowering in rice.
• Ehd3, encoding a plant homeodomain finger-containing protein, is a critical promoter of rice flowering.
• Increased transcription of Ghd7 under LD conditions and reduced transcription of downstream Ehd1 and FT-like genes in the Ehd3 mutants suggested that Ehd3 normally functions as an LD downregulator of Ghd7 in floral induction.
