Mutations in EVR rescue organ separation in nev flowers. (A) Wild-type flower after abscission (stage 17). (B) nev mutant flowers (stage 17) retain their floral organs indefinitely. (C) Organ shedding is rescued in nev evr flowers (stage 17). (D) evr flower after abscission (stage 17). (E-H) Longitudinal sections of wild-type (E), nev (F), nev evr (G) and evr (H) flowers (stage 16) stained with Toluidine Blue. In nev evr flowers (G), the remaining abscission zone (AZ) cells expand to a greater extent than do those of wild type (E). The sepal (se) and petal (pe) AZ regions are indicated, as are the nectaries (n). Scale bars: 50 μm.
