Rh5 and Rh6 function independent of norpA: Flies of the indicated genotypes were exposed to shifted LD cycles, followed by release into DD, exactly as described in the legend to Figure 2. Note that flies of the norpAP41; Rh52; Rh61 cryb/+ genotype (top row) served as norpA mutant cry+ controls. They quickly resynchronized to the new LD regime, as previously been reported for norpAP41 single mutants (Emery et al., 2000), despite being homozygous mutant for Rh52. Data were plotted and analyzed exactly as described in the legend to Figure 2 and in Materials and Methods. n for all data plots is indicated next to average actograms.
