Reversal of etiolation
Etiolated plants are those that have been grown in the dark, light stimulates increased [cytokinin] which stimulates cell division and greening.
increases [GA] which presumably stimulates IAA oxidase production to get rid of excess IAA that causes the long spindly growth.
IAA stimulates ethylene synthesis which maintains the apical hook, treating the apical hook with red light + ethylene maintains the hook.
