Fig. 2. Scanning electron micrographs of sunflower floret primordia at various developmental stages in wild type (WT) (A–D, I–L) and tubular ray flower (turf) mutant (E–H, M–P). (A) Stage 1 of WT ray floret buds (white arrows); at the periphery of the inflorescence, note stage 2 of disc floret primordia (black arrowheads). WT ray floret primordium development at stage 3 (B), stage 5 (C), and stage 6 (D). (E) Stage 1 of turf tubular-like ray floret buds (white arrows). turf tubular-like ray floret bud at stage 3 (F), stage 5 (G), and stage 6 (H). (I–L) Progression of WT disc floret primordia development from stage 1 to stage 4. (M–P) Progression of turf disc floret primordia development from stage 1 to stage 5. The stages of floret development are numbered according to Tähtiharju et al. (2012) (see Supplementary Table S21). Scale bars = 100 µm (A–E, G–P) and 50 µm (F).
