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.
Homozygous embryos show no overt defects in the salivary gland. Homozygous larvae show no overt cuticle defects. The lethal phase of Aats-trp homozygotes is either during the larval stage or the larval-pupal transition, depending on the mutant allele used. Females carrying homozygous germline clones do not produce any eggs, indicating that Aats-trp is required during oogenesis.
