Mycorrhizal colonization of roots treated with ethephon. Wild-type and ein2 mutants were treated with 0 (control) or 10 μg of ethephon applied to the leaf fortnightly. Plants were grown for 6 weeks in pot culture with Rhizophagus irregularis under low phosphate (0.05mM NaH2PO4) and scored for the percentage of roots possessing arbuscules or any internal fungal structures (hyphae, arbuscules, and/or vesicles). Values are mean±SE (n=6). Within a parameter, values with different letters above the bars indicate differences at P<0.05.
