Involvement of elements in the crosstalk between ethylene and light signaling in hypocotyl growth. COP1 and PIF3 are suppressed by light via phyB but activated by ethylene via EBF1/2-EIN3. In turn, ethylene-promoted EIN3 is inhibited by light via COP1 and phyB. Blue and dark indicates ethylene and light signaling, respectively.
