Fig. 4. — Delayed leaf senescence of ore14/arf2 mutants during dark-induced senescence. (A) Phenotypes of wild-type and ore14 mutant leaves. The third and fourth rosette leaves were detached at the age of 12 d and incubated in darkness; DAT, days after treatment. (B–D) Chlorophyll content (B), photochemical efficiency (F_v/F_m) of PSII (C), and membrane ion leakage (D) were examined every 2 d after dark treatment. Error bars indicate SD (n=24). (E) Expression of SEN4. Total cellular RNAs were isolated from wild-type and ore14-1/arf2-10 mutant leaves at the days indicated.
