Figure 4.

Temporal patterns of expression of the 206 enhancer trap-marked gene in the antennae of drop-dead vs. control males at 18°C. (A) Photomicrographs of whole-mount adult antennae reacted with X-Gal. Each is a typical example from over 10 flies at each age. (B) Relative amount of β-gal expressed in the antennae, plotted vs. chronological age. (C) Plotted vs. percent life span. Each animal contained one autosomal copy of the 206 enhancer-trap insertion, with or without drop-dead on the X-chromosome. (Bars = SEM.)
