Gene Details:

• MSU gene ID: LOC_Os01g69850
• RAPdb gene ID: Os01g0922800
• Gene Symbol: OsMADS51 OsMADS65
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In SDs OsMADS51 null mutants flowered 2 weeks later than normal, whereas in long days loss of OsMADS51 had little effect on flowering.
• Ectopic expression of OsMADS51 caused flowering to occur about 7 d earlier only in SDs.
• These results indicate that OsMADS51 is a flowering promoter, particularly in SDs, and that this gene functions upstream of Ehd1, OsMADS14, and Hd3a.
• In summary, OsMADS51 is a novel flowering promoter that transmits a SD promotion signal from OsGI to Ehd1.
• OsMADS51 is a short-day flowering promoter that functions upstream of Ehd1, OsMADS14, and Hd3a.
• The expression of Hd3a and FTL decreased in these transgenic plants, whereas the expression of Hd1, Early heading date 1 (Ehd1), OsMADS51, and OsMADS50 did not significantly change.
• In rice, the expression of Ehd1 is also controlled by the photoperiodic flowering genes OsGI (a rice ortholog of GI) and OsMADS51.
