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.
Mutant embryos have slightly smaller salivary glands than normal.
Homozygous embryos have defects in the longitudinal axon tracts, and EL neurons are missing.
The defect in attraction to sucrose of the shakB2 mutation is fully complemented by rununspecified.
