Gene Details:

• MSU gene ID: LOC_Os09g36910
• RAPdb gene ID: Os09g0540800
• Gene Symbol: OsFD1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Hd3a and OsFD1 negatively regulate rice resistance to Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola.
• In present study, we identified that Hd3a and OsFD1 expression is repressed by Xoo and JA, and validated that Hd3a and OsFD1 negatively regulate resistance to Xanthomonas oryzae pv.
• hd3a and OsFD1 mutants increase resistance to Xoo and Xoc, and activate JA responsive genes expression.
• However, whether Hd3a and OsFD1 play roles in defense is unclear.
• The functional confirmation of Hd3a and OsFD1 in rice defense makes them to be promising targets in molecular rice breeding.
• In rice, Hd3a, GF14 and OsFD1 proteins, forming florigen activation complex, are key components in flowering time regulation.
• The calcineurin B-like-interacting protein kinase, OsCIPK3, directly interacts with OsFD1 and phosphorylates OsFD1, which could facilitate FAC to localize in the nucleus.
• Phosphorylation of OsFD1 by OsCIPK3 Promotes the Formation of RFT1-containing Florigen Activation Complex for Long-day Flowering in Rice.
• We show that RFT1 forms a ternary FAC with 14-3-3 proteins and OsFD1 for flowering under LDs.
• Our results suggest that OsCIPK3 phosphorylates OsFD1 for RFT1-containing FAC formation to initiate flowering in rice under LDs.
