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 clones induced in larval imaginal discs grow poorly compared to their wild-type sibling clones when raised on reduced yeast levels (20% yeast compared to standard food medium). Mutant flies are more susceptible to paraquat feeding than control flies.
