The neuromuscular junction appears grossly normal in homozygous third instar larvae; the number of boutons, total synaptic area, average muscle surface area and the bouton number/muscle surface area not altered compared to wild-type controls.
Homozygous third instar larvae have axon commissure defects, with apparent discontinuities in the commissure (all larvae have at least one discontinuity and 89% have 2 or more as assayed by Fas3 immunoreactivity).
Mutant larvae have defects in the patterning of the body-wall muscles. Most frequently, muscles 6 and 7 appear crossed (instead of running parallel as in wild type), appearing to insert improperly at the insertion site of the other. Muscle 5 shows two types of defect; it is either abnormally thin or absent altogether. Branched muscle fibres are also seen at several positions.
Homozygous females lay on average only 1.2 eggs/day. None of the eggs hatch.
Homozygous mothers re unable to lay eggs, except in rare cases. Egg development in mutant mothers in retarded and the lower extremity of each ovary is occluded by shorter than normal eggs displaying deformed egg appendages. The rows of blocked egg chambers remain in the ovaries and later degenerate. Few mature eggs are deposited. They are all shorter and smaller in size than normal, and their dorsal appendages are reduced in length, flattened and frequently fused. Mutant egg chambers exhibit a dumpless phenotype. Homozygous mutant clones in the follicle cells exhibit a wild-type phenotype, but mutant germ-line clones give rise to a dumpless phenotype. Although ring canals in mutant egg chambers reach a diameter similar to wild-type rings they are partially occluded by an apparently loose masses of actin filaments often organised in concentric rings with a small opening in the central area.
In rare cases, homozygous males produce a few offspring when mated with wild-type females. Homozygous male and female adults appear morphologically wild type. Homozygous testes do contain large numbers of elongated sperm bundles, but squashed testes release few, if any, motile sperm and no sperm are observed in the seminal receptacle or spermathecum of wild-type females mated to homozygous males. A large number of spermatids fail to individualise in homozygous testes and remain syncytial. Normal appearing individualisation complexes are seen. The organisation of the sperm axonemes and structure of the minor and major mitochondrial derivatives appear normal. Eggs laid by homozygous females are smaller than normal and appear deflated. Dorsal appendages are missing, fused together or otherwise severely deformed. The chorions are thinner than normal.
