Summary

ABSTRACT: Clinal variation for repeat number in the Thr-Gly region of the period circadian timing gene in Drosophila melanogaster was described in Europe and has subsequently been used as evidence of thermal selection on period alleles. To test for clinal variation in this gene along the east coast of Australia, the period polymorphism was scored on flies from multiple samples collected repeatedly over a 5-year interval, along with variation at another circadian rhythm locus, clock. For period, there was no consistent evidence of clinal variation in the 17 and/or 20 repeat alleles, although when average allele length was examined a weak consistent clinal pattern was detected. For clock there was no evidence of clinal variation in the two most common alleles or in average repeat size. These data are inconsistent with the reported patterns in Europe and suggest that clinal variation in timing genes needs to be re-examined in this region.

Datasets

  • 48 Weeks et al. 2005, Clock locus

    This data set contains frequencies of the two most common alleles (repeats 31 and 29) of the Gln clock gene for 18 Drosophila melanogaster populations collected in 2004 (Fig. 4). Note longitudes in data are approximate.

  • 49 Weeks et al. 2005, Period locus

    This data set contains frequencies of the (Thr-Gly)17 and (Thr.Gly)20 period allele (Frequency17 and Frequency20) for 18 Drosophila melanogaster populations collected in 2004 and for 16 populations collected 2002 (Fig. 1).

  • 50 Weeks et al. 2005, Thr-Gly locus

    This data set contains mean Thr-Gly repeat length for 18 Drosophila melanogaster populations collected in 2004 and for 20 populations collected 2002 (Fig. 2). Note longitudes in data are approximate.
