Gene Details:

• MSU gene ID: LOC_Os02g40510
• RAPdb gene ID: Os02g0618200
• Gene Symbol: OsPRR1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Flowering genes downstream of OsPRR1 such as OsGI and Hd1 were down regulated in the A654 mutant.
• In addition, OsPIL13 and OsPIL15 colocalize with OsPRR1, an ortholog of the Arabidopsis APRR1 gene that controls photoperiodic flowering response through clock function.
• Together, these results suggest that overexpression of OsLF might repress expression of OsGI and Hd1 by competing with OsPRR1 in interacting with OsPIL13 and OsPIL15 and thus induce late flowering.
