FT — Solanum lycopersicum

Summary

SOLYC05G053850.3 (SP5G/FT) encodes a phosphatidylethanolamine-binding protein (PEBP family) on tomato chromosome 5. The gene product is associated with DNA binding transcription factor activity, sequence-specific DNA binding, and protein homodimerization activity, and has been linked to mRNA regulatory element binding translation repressor activity and peptide-O-fucosyltransferase activity. In tomato, SP5G is associated with growth habit, photoperiod sensitivity, and heat tolerance. The gene is associated with flower formation, floral whorl development, meristem determinacy, response to short-day conditions, and maintenance of floral meristem identity. Associations also include yield, fruit set, inflorescence branching, leaflet shape, and vegetative vigor. Localization evidence links the protein to the plasmodesma, ER, Golgi, plastid, and cytosol. Studies of related genes in other species connect the family to tuber formation, photoperiod response, inflorescence architecture, and endosperm development.
