Simplified Schematic Model Representing BBX19 as a Gatekeeper of Evening Complex Formation through Recruitment and COP1-Mediated Degradation of ELF3 Leading to Hypocotyl Elongation.

(A) Model of evening complex (ELF4/ELF3/LUX) repression of PIF4/5 expression and inhibition of hypocotyl elongation modified from Nusinow et al. (2011).

(B) Model of BBX19 depletion/reduction of the ELF3 pool for evening complex formation through recruitment and COP1-dependent degradation of ELF3, enabling PIF4 and PIF5 expression and, consequently, hypocotyl growth.
