Influence of ethylene signaling on fus3 vegetative phase transition. (A) Mature rosette leaf morphologies of fus3 and fus3 ein2-1 plants. Leaves from 12 plants were dissected, and a representative profile is shown. Scale bar = 1.0 cm. (B) Ratios of blade-to-petiole lengths of mature individual rosette leaves from fus3 and fus3 ein2-1 plants. (C) Percentage of rosettes displaying trichomes on the abaxial surface at each leaf position. (D) Rosette leaf morphology of fus3 germinated for 2 days in minimal medium (MS) in the presence (+) or absence (-) of 100 μM AgNO₃ (Ag) and then transferred to soil. Leaves from ten plants were dissected, and a representative profile is shown. Scale bar = 1.0 cm. (E) Ratios of blade-to-petiole lengths of individual fus3 rosette leaves of plants germinated in MS with (+) or without (-) 100 μM AgNO₃ (Ag).
