Figure 4. Expression of ebony+ in glia is sufficient to rescue the rhythm phenotype of the e1 mutant. Overexpression of ebony+ in a wild-type background has no obvious effects.

Figure 4

(A) Actograms for representative control flies, e1 mutants, rescued mutants, and individuals overexpressing Ebony in an e+ background. Data are from the DD portions of the records starting with the first day after lights-off. The horizontal bars beneath records indicate subjective day and night. The overexpression of Ebony in an e1 mutant background, using a glial cell driver (repo-Gal4), rescued circadian behavior. Overexpression of Ebony in a wild-type background had no effect on rhythmicity. All flies were in a w1118 genetic background. Repo > ebony+ = w1118; repo-Gal4, e1/UAS-ebony+, e1. (B) Body color phenotypes of various genotypes. i) w1118. ii) w1118; e1/e1. iii) w1118; actin-Gal4/+; UAS-ebony+, e1/e1. iv) w1118; repo-Gal4, e1/UAS-ebony+, e1.
