Clock mutations alter developmental timing in Drosophila

Heredity (Edinb). 1990 Jun;64 ( Pt 3):395-401. doi: 10.1038/hdy.1990.50.


The developmental time of period mutants in Drosophila melanogaster was monitored under different environmental conditions. We observed that the pers mutants, which have short 19 h circadian cycles, develop faster from eggs to adult than the wild-type: perL mutants, which have long 28 h circadian rhythms, complete development more slowly than the wild-type. These results suggest that endogenous timers may be involved in regulating the development time of D. melanogaster.
