Figure 5.

Sb-like bristle generated by expression of the S737A transgene. Confocal image (negative image) of phalloidin-stained bristles dissected from pupae at 37 hr AP following heat shocks at 25, 27, 29, and 31 hr AP. (Left) An Sb-like bristle from an S737A transgene-carrying pupa [S737A/S737A; Df(3R)sbd¹⁰⁵/+]. (Right) A normal bristle from a wild-type control pupa (wt) also subjected to the same heat-shock regimen. The tip of the much longer wild-type bristle cannot be seen in this view. The entire S737A bristle is shown. Bars, 5 μm.
