Fig. 2. Colocalization of GFP spots and lac operator FISH signals in Dex-treated 2C leaf nuclei of homozygous EL702L plants. (A) Percentage of nuclei with one to four GFP spots compared to FISH signals. Fewer GFP spots than FISH signals may occur in one nucleus. (B) Examples of nuclei with 1, 2, 3 or 4 GFP spots coinciding with lac operator FISH signals. Bars, 3 µm.
