Key message

• OsFTIP1, RFT1, OsFTIP1-Mediated Regulation of Florigen Transport in Rice Is Negatively Regulated by a Ubiquitin-like Domain Kinase OsUbDKγ4., Here we show that rice FT-INTERACTING PROTEIN 1 (OsFTIP1), a member of the family of multiple C2 domain and transmembrane region proteins (MCTPs) and the closest ortholog of Arabidopsis FTIP1, is required for export of RICE FLOWERING LOCUS T 1 (RFT1) from companion cells to sieve elements
• OsFTIP1, RFT1, OsFTIP1-Mediated Regulation of Florigen Transport in Rice Is Negatively Regulated by a Ubiquitin-like Domain Kinase OsUbDKγ4., We further reveal that a ubiquitin-like domain kinase γ4, OsUbDKγ4, interacts with OsFTIP1, and modulates its degradation in leaves through the 26S proteasome, which in turn affects RFT1 transport to the SAM
• OsFTIP1, RFT1, OsFTIP1-Mediated Regulation of Florigen Transport in Rice Is Negatively Regulated by a Ubiquitin-like Domain Kinase OsUbDKγ4., Thus, dynamic modulation of OsFTIP1 abundance in leaves by a negative regulator OsUbDKγ4 is integral to the role of OsFTIP1 in mediating RFT1 transport in rice, and provide key evidence for a conserved role of FTIP1-like MCTPs in mediating florigen transport in flowering plants
