Fig. 1. Ethanol-induced restoration of the ufo-2 mutant. Plants were not
induced (A-D) or induced for 5 days by ethanol after 3 weeks culture under
Long Days. (E-H). The apices were observed 18 days after the beginning of the
treatment. No difference in floral morphology was observed between wild type
(A,E) and ufo-2 (B,F) lines whether treated or not treated with
ethanol. Flowers of ufo-2 35S::uidAind transgenics
carrying an inducible GUS construct (C,G) were not modified by ethanol
induction. (D,H) In ufo-2 35S::UFOind ethanol-induced
expression of UFO restored petals and stamens and wild-type flowers
(arrows) could be observed (H).
