FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
mew[+]/mewunspecified is a non-enhancer of abnormal neuroanatomy | embryonic stage phenotype of Scer\GAL4P52, Sema1aUAS.cYa, Sema1ak13702
mew[+]/mewunspecified is a non-suppressor of abnormal neuroanatomy | embryonic stage phenotype of Scer\GAL4P52, Sema1aUAS.cYa, Sema1ak13702
mewunspecified is an enhancer of muscle attachment site & basal lamina phenotype of ifB4
mew[+]/mewunspecified is a non-enhancer of larval posterior commissure | embryonic stage phenotype of Scer\GAL4P52, Sema1aUAS.cYa, Sema1ak13702
mew[+]/mewunspecified is a non-suppressor of larval posterior commissure | embryonic stage phenotype of Scer\GAL4P52, Sema1aUAS.cYa, Sema1ak13702
ifB4, mewunspecified has muscle attachment site phenotype
The commissural axon phenotype (failure to cross the midline) seen in embryos expressing Sema-1aScer\UAS.cYa under the control of Scer\GAL4P52 in a Sema-1ak13702 null background is not affected if the embryos are also heterozygous for mewunspecified.
ifB4 mewunspecified double mutant embryos have a more severe muscle detachment phenotype than ifB4 single mutant embryos. The basement membrane detaches or fails to assemble in epidermal HAJs in these embryos.
