Fig. 3. Phenotypes of jag-5D mutants. (A-C) Inflorescences of wild-type (A), jag-5D heterozygous (B), and jag-5D homozygous plants (C). White arrow points to flower subtended by a bract, black arrow points to a bractless flower. (D) Examples of bract development on the inflorescence of jag-5D heterozygous mutants including filamentous, (top left), and large laminar bracts (bottom center). Note jagged edges and pointed tips of bracts, and lack of defined petioles. (E) SEM of stipules at the base of a bract of a jag-5D homozygous mutant (arrows). (F) Example of suppression of floral identity in a jag-5D homozygote. Arrow points to a leafy shoot. (G) Example of ectopic co-florescence in jag-5D heterozygote (arrow). (H) Wild-type rosette leaf with typical paddle shape. Bracket marks petiole. (I) In jag-5D mutants, blade tissue develops ectopically on petiole. (J) Ectopic blade tissue on the stem of shoots that develop in the axils of rosette leaves (bracket marks ectopic blade). (K) SEM of a wild-type inflorescence apex. (L) SEM of a jag-5D heterozygote. Arrowhead points to a bract primordium (br). Scale bar: 100 µm (E,K,L).
