Detailed Description

Statement

Reference

Expression of Csp^2.Scer\UAS under the control of Scer\GAL4^elav-C155 in a wild-type background has no significant effect on evoked excitatory junction potential amplitude at the neuromuscular junction in larvae. Features of spontaneous release are also normal in these larvae. Expression of Csp^2.Scer\UAS under the control of Scer\GAL4^elav-C155 or Scer\GAL4^hs.PB results in temperature-sensitive lethality, with the animals dying during the third larval instar stage at 29^oC. The lethality caused by expression of Csp^2.Scer\UAS under the control of Scer\GAL4^hs.PB is more severe in male than in female flies. Adult escapers carrying Csp^2.Scer\UAS expressed under the control of Scer\GAL4^elav-C155 have a shorter life span than normal at 25^oC. The flies are extremely sluggish, show severely uncoordinated movements, and slip frequently. Body size is severely reduced and wing inflation is impaired, so that the wings appear severely crumpled. The regular ommatidial pattern is disrupted so that the eye appears rough. The eye is slightly elliptical in shape and some bristles are lost. Fusion of several ommatidial units is occasionally seen.

Additional Comments

Genetic Interactions

Statement

Reference

Expression of Csp^2.Scer\UAS under the control of Scer\GAL4^elav-C155 does not rescue the reduced amplitude of the excitatory junctional potential at the Hip14²/Df(3L)brm11 neuromuscular junction at 23^oC.

Expression of Csp^2.Scer\UAS under the control of Scer\GAL4^elav-C155 does not rescue the reduced amplitude of the excitatory junctional potential at the Hip14¹/Hip14² neuromuscular junction at 30^oC.

(Ohyama et al., 2007)

The crumpled wing and rough eye phenotype of adult escapers carrying Csp^2.Scer\UAS expressed under the control of Scer\GAL4^elav-C155 is partially suppressed by Syx1A^hs.PW at 25^oC and completely suppressed by daily heat shocks during late larval and pupal development in these flies (which increase expression of Syx1A^hs.PW). The mean evoked excitatory junction potential (EJP) amplitude at the neuromuscular junction is reduced by about 34% compared to wild type in larvae expressing Syx1A^hs.PW at 25^oC. The EJP amplitude is normal if the larvae are also expressing Csp^2.Scer\UAS under the control of Scer\GAL4^elav-C155.

Comments

Expression of Csp^2.Scer\UAS under the control of Scer\GAL4^elav-C155 has no effect on spontaneous miniature excitatory junction potentials at the neuromuscular junction of Csp^R1 third instar larvae, but does rescue the evoked excitatory junction potential at the neuromuscular junction.
