Protein function
Encodes a repressor of UV-B photomorphogenesis.
Phenotype
Overexpressor: EFO1 overexpressor is early flowering under both SD and LD conditions.
[Wang et al., 2011] Multiple mutant: efo1;
efo2 multiple mutant shows additive effects on multiple developmental aspects (rosette size, hypocotyl length, etc.).
efo1;
efo2 multiple mutant flowers later than
efo2 single mutant.
[Wang et al., 2011] Function:Functions in association with RUP2 as repressor of UV-B-induced photomorphogenesis mediated by UVR8 and HY5. Plays a crucial negative feedback regulatory role downstream of UVR8-COP1 to inhibit UVR8 function, balance UV-B-specific responses and ensure normal plant growth. Is involved in the regulation of photoperiodic flowering and vegetative development.
