65% of hemizygous files show no or only weak entrainment to temperature cycles in assays studying locomotor rhythms.
smetunspecified/Df(2L)Rev18 larvae have reduced touch sensitivity compared to wild-type. Locomotion in these larvae is aberrant: compared to controls they are slower and they pause, turn and retreat more often. These defects in locomotion arise at least partially from defective peristaltic motion: stride period and % positive and negative flow are altered compared to wild-type and the larvae spend the majority of a single peristaltic cycle in a retracted position.
nocted07154 ; smetunspecified double mutant flies show more severe defects in entrainment to temperature cycles than either single mutant in assays studying locomotor rhythms, indicating an additive effect.
