FT — Sorghum bicolor

Summary

SORBI_3004G206600 (SbFT) encodes a phosphatidylethanolamine-binding protein (PEBP family member) with DNA-binding transcription factor activity, mRNA regulatory element binding translation repressor activity, and protein O-GlcNAc transferase activity. SbFT is associated with photoperiodism, particularly response to short-day and long-day photoperiodism for flowering, vernalization response, floral whorl development, meristem determinacy, and secondary shoot formation. The gene has been connected to photoperiod-sensitive flowering time, inflorescence development and morphology, spikelet floret size, node number, stem length, vegetative vigor, plant male sterility, and temperature stress response. Localization evidence links SbFT to the plasmodesmata, endoplasmic reticulum, plastid, and cytosol. Studies of related genes in other species link the family to photoperiodic flowering, floral transition, and inflorescence architecture, as well as days to tassel.
