Fig. 4

Transient expression analysis of the Bctra putative core promoter. The DsRed gene was used as a reporter. The #1215-Bctra-DsRed injected embryos were investigated. The left column figures (a, c, e, and g) are investigated under bright-field microscopy and the adjacent figures (b, d, f, and h) are the same embryos under epifluorescence. (a) and (b) represent an uninjected embryo. (d), (f), and (h) are the injected embryos at 31 hours after egg-laying and show red fluorescence.
