EARLY FLOWERING 5 (ELF5) is a single-copy gene involved in flowering time regulation in Arabidopsis. ELF5 encodes a nuclear-targeted protein that is related to the human nuclear protein containing a WW domain (Npw)38-binding protein (NpwBP). Lesions in ELF5 cause early flowering in both long days and short days. elf5 mutations partially suppress the late flowering of both autonomous-pathway mutants and FRIGIDA (FRI)-containing lines by reducing the expression of FLOWERING LOCUS C (FLC), a floral repressor upon which many of the flowering pathways converge. elf5 mutations also partially suppress photoperiod-pathway mutants, and this, along with the ability of elf5 mutations to cause early flowering in short days, indicates that ELF5 also affects flowering independently of FLC.
