Mutants die at the late embryo/early first larval instar; a small minority of mutant larvae (less than 10%) hatch from the egg case but they all die during early to mid 1st instar. No gross morphological abnormalities are seen; the body plan appears fully differentiated and there are no defects in epidermal segmentation or patterning. The gut, tracheal system, musculature and nervous system appear fully differentiated with no detectable morphological abnormalities. Mutant neuromuscular junctions appear well differentiated with normally sized boutons and terminal size and number of boutons appears normal. Mutants show severe sluggishness, reduced endogenous locomotory movements and a lack of response to nose-touch. At a basal stimulation level, mean EJC amplitude at the embryonic neuromuscular junction (NMJ) is reduced by about 50% compared to controls.
CadpsBD has lethal | recessive phenotype, suppressible by Rnor\CadpsUAS.cRa/Scer\GAL4e22c
CadpsBD, Rnor\CadpsUAS.cRa, Scer\GAL4e22c has viable phenotype
CadpsBD, Rnor\CadpsUAS.cRa, Scer\GAL4e22c has wild-type phenotype
CapsBD flies expressing Rnor\CAPSScer\UAS.cRa under the control of Scer\GAL4e22c have no detectable morphological or behavioural defects.
Selected as: mutation that is lethal over Ts(1Lt;4Lt)scH.
