Detailed Description
Statement
Reference

The electroretinograms (ERGs) of flies in which the eyes are composed of homozygous tissue are abnormal; they lack the on and off transients, but depolarisation is normal.

Mutant photoreceptors in flies in which the eyes are composed of homozygous tissue have a regular display of terminals in the medulla and show no obvious defects in axonal targeting. Ultrastructural analysis of the photoreceptor synapses in the lamina shows that capitate projections are often shallow in mutants compared with controls.

Third larval instar neuromuscular junctions (NMJs) have normal morphology in Hip142/Df(3L)brm11 mutants. Ultrastructural analysis of the NMJ boutons indicate that synaptic vesicle morphology and density, T-bar morphology, active zone length and the structure of the subsynaptic reticulum are all normal in the mutants.

Hip142/Df(3L)brm11 mutant third larval instar NMJs take up less dye than controls in an assay of vesicle cycling.

Hip142/Df(3L)brm11 mutant third larval instar NMJs have similar miniature excitatory junctional potential (EJP) amplitude and frequency compared to controls. However, the evoked EJP amplitude is reduced compared to controls at 23oC and severely reduced compared to controls at 30oC.

Expression of Csp::n-sybTMD.Scer\UAS under the control of Scer\GAL4elav-C155 partially rescues the reduced amplitude of the excitatory junctional potential at the Hip142/Df(3L)brm11 neuromuscular junction at 23oC.

Expression of Csp::n-sybTMD.Scer\UAS under the control of Scer\GAL4elav-C155 partially rescues the reduced amplitude of the excitatory junctional potential at the Hip141/Hip142 neuromuscular junction at 30oC.

Expression of Csp2.Scer\UAS under the control of Scer\GAL4elav-C155 does not rescue the reduced amplitude of the excitatory junctional potential at the Hip142/Df(3L)brm11 neuromuscular junction at 23oC.

Associated with: a separable lethal mutation on the chromosome; homozygotes show third larval instar lethality in comparison to the late pupal lethality of hemizygotes with Df(3L)brm11, and the homozygous lethality is not rescued by Hip14+t6.5 (whereas the hemizygous lethality is rescued by Hip14+t6.5).
