Fig. 6. Induction of UFO expression at different floral stages of ufo-2 35S::UFO_ind. ufo-2 35S::UFO_ind plants were ethanol-induced (A-E) after various durations of floral induction by long day treatment or were not ethanol-induced (F). Ethanol induction after 12 LD has no major effect on floral morphology of the five oldest flowers (A). Induction after 9 LD leads to a majority of type I flowers (B). After 8 LD, ethanol induction leads to a majority of type III flowers (C). Type IV and mutant-type (mt) flowers are observed following induction after 7 LD. (D). Mutant-type flowers develop on treated apices after 5 LD (E) as in non-induced plants (F). nd, flower that could not be classified as a type I-IV or a mutant flower. Bar: 100 µm.
