FT — Sorghum bicolor

Summary

SORBI_3006G128500 (SbFT) on sorghum chromosome 6 encodes a phosphatidylethanolamine-binding protein (PEBP family) with annotated DNA-binding transcription factor activity, mRNA regulatory element binding translation repressor activity, and protein O-GlcNAc transferase activity. This gene is associated with photoperiodism and flowering time, including response to short-day and long-day photoperiods, vernalization response, and floral whorl development. It has been connected to numerous agronomic traits such as photoperiod-sensitive flowering time, inflorescence development and morphology, spikelet floret size, stem length, shoot axis branching, plant male sterility, and stress responses including drought and temperature stress. Localization evidence links the product to plasmodesmata, plastids, and the ER. Studies of related genes in other species connect the PEBP family to floral transition, inflorescence architecture, and drought escape responses.
