  • aFlies were kept at 25°C and exposed to 4 d of LD cycles, followed by 7 d of DD.

  • bIndependent transgenic lines are designated by the numbers in parentheses.

  • cPower is a measure of the strength or amplitude of the rhythm in arbitrary units.

  • dPercentage of flies showing locomotor rhythms with a power value of ≥10 and a width value of ≥2.

  • eTotal number of flies that survived until the end of the experimental period.
