Fig. 7. Histochemical assay for GUS activity in seedlings expressing PFCA::FCAto exon 5:GUS in a Ler or fca-1 background. (A–D) PFCA:: FCAto exon 5:GUS (Ler) at 2 (A), 4 (B), 6 (C) and 10 (D) days after germination. (E–H) PFCA::FCAto exon 5:GUS (fca-1) at 2 (E), 4 (F), 6 (G) and 10 (H) days after germination. All panels show seedlings incubated with X-Gluc for 16 h.
