Breakpoint from FlyBase's release 5 sequence location of progenitor insertion.
The size and frequency of miniature excitatory junction potentials (mEJPs) from muscle 6 of Df(1)Exel9051/Y mutants does not differ from that of wild-type. However, the size of excitatory junction potentials (EJPs) is reduced in Df(1)Exel9051/Y mutants compared with wild-type.
Under dim light conditions, the distance travelled by mutant third instar larvae in one minute at 20-22[o]C is not significantly different from wild type. The frequency of peristaltic contractions under these conditions is normal in the mutant larvae. However, under bright light at 27-30[o]C (stress conditions) the mutant larvae travel significantly less far than wild type in one minute. Under these conditions, the frequency of peristaltic contractions is reduced in the mutant larvae compared to wild type.
FlyBase curator comment: The aberration chromosome previously referred to as "Df(1)Exel9054" is in fact identical to Df(1)Exel9051 (generated using the same progenitor insertions), and thus the two entries have been merged in the database.
