Enhancer activity displayed by the HCNRs in stable transgenesis at 24–48 hpf.

Table summarizing the GFP expression patterns and the enhancer activity found in the study. The “+” symbol in the enhancer activity column symbolizes the strength of the expression patterns according to GFP expression levels regardless of the similarity among founders. The “−” symbol represents the absence of activity. Columns 4–11 refer to the number of founders showing GFP expression on each territory. A CNE was classified as “negative” if at least two founder lines did not show any GFP expression. To annotate the expression pattern of any positive CNE, at least three stable transgenic lines were analysed. “Booster” refers to HCNRs that, when in different stable lines, drive expression in very different patterns, as if boosting the position effects.
