Gene Details:

• MSU gene ID: LOC_Os04g55510
• RAPdb gene ID: Os04g0648800
• Gene Symbol: OsHIP1 HAF1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The RING-Finger Ubiquitin Ligase HAF1 Mediates Heading date 1 Degradation during Photoperiodic Flowering in Rice.
• The HAF1 mutant exhibits a later flowering heading date under both short-day and long-day conditions.
• In addition, the HAF1 hd1 double mutant headed as late as hd1 plants under short-day conditions but exhibited a heading date similar to HAF1 under long-day conditions, thus indicating that HAF1 may determine heading date mainly through Hd1 under short-day conditions.
• HAF1 Modulates Circadian Accumulation of OsELF3 Controlling Heading Date Under Long-day Conditions in Rice.
• An amino acid variation (L558S) within the interaction domain of OsELF3 with HAF1 greatly contributes to the variation in heading date among japonica rice accessions.
• Taken together, our findings suggest that HAF1 precisely modulates the diurnal rhythm of OsELF3 accumulation to ensure the appropriate heading date in rice.
