ELF3 — Brachypodium distachyon

Summary

Brachypodium distachyon gene ELF3 (BRADI_2G14290V3) encodes an ELF3-like protein with multiple annotated molecular functions including receptor tyrosine kinase binding, phytochromobilin:ferredoxin oxidoreductase activity, histone kinase activity, auxin receptor activity, and phosphatidylethanolamine binding. It is associated with upregulation of short-day photoperiodism and flowering, positive regulation of thermomorphogenesis, photoentrainment of the circadian clock, chloroplast-nucleus signaling, and regulation of auxin biosynthesis. The gene is linked to numerous traits including drought stress response, photoperiod sensitivity, leaf area, panicle number, inflorescence length, chlorophyll ratio, spot blotch, and glyphosate sensitivity. It localizes to chromatin, nuclear speck, the SCF complex, and plasmodesmatal ER. Studies of related genes in other species link the ELF3 family to circadian regulation, photoperiod sensitivity, drought stress resistance, and heading time.
